Description

201039339 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to the field of framing n used for striking chord music synthesis (APHAMS), which simulates emulation and sub-media through physical layout The steeipan instrument senses the melody pattern and uses MIDI technology to synthesize a range of tone production. [Prior Art] According to its development with the apparatus of the present invention and the development of the apparatus of the present invention, an internal synthesis using internal electronic components and/or an externally synthesized drum of a jMID1 agreement, a steel drum and - General strike devices are known in the prior art. Regarding the apparatus of the present invention, conventional sound steel drum musical instruments suffer from several drawbacks and significant drawbacks, regardless of their novelty and appeal. First, as evidenced by the need to implement a number of discrepancies on multiple drums, it is virtually impossible to fabricate a steel drum that can cover the widest range of possible musical ranges from bass to P-range on a single drum. This limitation is imposed by the physical size of the notes and the size of the drum in use. In particular, due to the fact that the size of the note is dramatically increased due to the decrease in the scale, the arrangement of the notes of the music cycle of the = and fifth notes is only used in a single drum to achieve the sub-range of the most musical range. Steel drums are available on the drum. One of the direct results of this limitation is that the instrument is not easily portable except for the higher range of up to two or three drums. In addition, the obvious disadvantage is caused by the difficulty of retuning the instrument, because the tuning spectrum may be tuned by an expert using W after extensive use, playing or changing the temperature of the instrument. It is highly desirable to produce a steel drum that delivers true and self-sounding range and does not need to be tailored to the need to optimize the sound and continue to maintain the instrument as a tuned. ° Finally 'Although the instrument has introduced a new performance style, the player can produce a melody sound by hitting a note on a single metal surface, but the king is removed by the change in the way the note is used. In addition to the subtle changes in the tone of the jade, traditional instruments do not have the flexibility to allow rapid changes in the tone or voice. Because it has been associated with the continual evolution of the apparatus of the present invention or has an impact on the forward evolution of the apparatus of the present invention, there are various musical instruments, including electronic drums that utilize the universal MIDI standard. The electronic keyboard percussion instrument of U.S. Patent No. 4,892,023 issued to Takeuehi et al. uses one of the plates configured in a manner similar to a standard keyboard. The instrument is played like a xylophone. The output of the sensor attached to the boards is used to trigger the generation of a synthesized tone corresponding to the specified note. The design also facilitates a wired connection to a MIDI network to extend the range of voices that can be accessed. However, the above-mentioned electronic keyboard percussion instrument does not support four-degree and fifth-degree note configurations, which does not allow for other changes in the note configuration. In addition, it does not support ten (10) notes of polyphonic music, and the physical configuration of the board does not promote finger performance. Finally, the instrument does not promote wireless capability without external components. Electronic drum instruments (such as U.S. Patent No. 140,180, doc to U.S. Patent No. 4,039, 339, issued to U.S. Patent No. 4, s, issued to U.S. Pat. U.S. Patent No. 5,434,350, issued to U.S. Patent No. 5,061,131 issued to Patterson, utilizes a pressure sensitive pad array and electronic components to produce a MIDI output for tone generation or for direct internal sound synthesis. These electronic drum instruments have been designed for the main purpose of synthesizing sound drums. Similarly, the number of pads available is typically limited to only twelve (12), i.e., a single octave. Moreover, as a result of the original design intent for drum synthesis, the size, configuration, and other physical attributes of the pads do not promote an ergonomic, musical intuition note configuration for the performance of the melody music. The use of electronic drums is well known in the prior art because it relates to the apparatus of the present invention. For example, U.S. Patent No. 4'7, issued to B. Z., et al., discloses an electronic drum having a plurality of sound sources having rapidly detachable striking elements and piezoelectric sensors. However, the invention of the above patent does not utilize an electronic synthesizer to deliver the natural sound of the steel drum. In addition, the patent does not reveal a mixture of other instruments with the sound of steel drums. U.S. Patent No. 4,679,479, issued toK. However, the invention of this patent does not use an electronic synthesizer to deliver the natural sound of a steel drum. Moreover, this patent does not disclose a mixture of other instruments having the sound of a steel drum. In addition, the US patent design D3 19 65 issued to Hart. No. Reveals the design of the electronic drum. However, it is claimed herein that the present invention has 140180.doc 201039339 early hitting the surface and does not use an electronic synthesizer to deliver the natural sound of a steel drum. Moreover, this patent does not disclose a mixture of other musical instruments having the sound of a steel drum. In the end, U.S. Patent No. 5, 502, 274, issued to I. The instrument of construction and design. An electronic musical instrument for playing along with pre-recorded music is disclosed in U.S. Patent No. 5,502,274 issued to I. However, this instrument does not focus on producing the true and natural sound of the drum drum. U.S. Patent No. 6,212,772 to Whitmyre discloses a Caribbean steel drum. However, this instrument does not reveal a device that uses electronic components to simulate a conventional steel drum. A portable drum and carrier are disclosed in U.S. Patent No. 5,973,247, issued to Matthews. Again, in this article, the instrument does not reveal devices that use electronic components to simulate conventional acoustic steel drums. U.S. Patent No. 7, 3, 3, 5, B1, issued to Cupid, uses a matrix of pressure sensitive pads in an ergonomic frame modeled along the line of conventional sound steel drums. However, while the above invention caters to the electronic simulation of all existing sound steel drum ranges from low to high midrange, the above invention does not allow the pressure sensitive pad matrix to be arbitrarily configured. Similarly, although the design captures the true analog of all existing sound steel drum ranges from bass to high midrange by copying the physical form of these instruments, the invention requires the use of two, three Or even six separate playing surfaces and the invention does not facilitate full simulation of the steel drum by producing a timbre change when hitting different portions of the pressure sensitive pads. In particular, although the above invention supports four- and five-degree note configurations, the invention does not facilitate any variation in note configuration, and there is neither support for ten (1 〇) note-repeated music, entities of such pads The design also does not promote finger performance. Moreover, the above invention does not promote wireless MIDI capability without external devices, nor does it allow control of devices on a MIDU. The above invention allows only the synthesis of various ranges of steel drums, does not emphasize the synthesis of various voices of a wider range, and supports only twenty-eight (28) notes. Thus, in summary, the aforementioned invention does not support the simultaneous synthesis of multiple speeches and it does not facilitate full simulation of the steel drum instrument by creating a timbre change when striking different portions of the pressure sensitive pad. The apparatus of the present invention provides for the disadvantages of the above-described examples of conventional-like acoustic steel drums, electronically synthesized steel drums, electronic keyboard percussion instruments, and other known types of similar instruments that are present in prior art t. : Appropriately innovative melody devices that overcome the above disadvantages and further disadvantages, with the given drawbacks previously stated in the prior art. Similarly, the general purpose of the invention, which will be described in more detail hereinafter, is to provide a new and improved melody device which has the advantages of the prior art described above and many other novel features which are not A melody device is contemplated by the prior art, either alone or in combination with any of the following, resulting in an apparent, suggestive or even implicit suggestion.

Referring now to Figure 1, there is shown a top level overview of the apparatus of the present invention. 140180.doc 14 201039339 The highest level schematic of Figure 1 is a conceptual model of the apparatus of the present invention, f providing a template for the design of the device for use in the present invention. As a rain-rain level overview, it is not explicitly referenced to hardware or software subsystem implementations, but is limited to the conceptual procedures required for the functionality of the present invention. The schematic uses the Gane-Sarson convention, and thus represents the input and output interfaces by means of a closed rectangle representing the data storage area by a rectangular shape representing a-beauty conversion program. The information movement is indicated by an arrow. 'Division of the main diagram 1 into two main sections: playing surface input section 2, X, C including the notes required by the 'student to generate and modulate a performance and are the most visible on the invention The entire interface of the user interface object is an additional face section 4 that incorporates all other interfaces required for further interaction with the user and the external environment; and finally, the main operating program section 3, the 纟 link playing surface input section 2 to the additional interface section 4 and thus incorporate all the programs needed to transform the input data to produce all the required outputs. It should be noted that different embodiments of the apparatus of the present invention can implement the primary operating procedure 3 of this overview entirely in hardware, entirely in software, or a combination of both. In this regard, the same reference numerals are referenced in the other figures in the figures referring to the hardware or software perspective of the same entity. The input encased in the performance surface input section 2 includes a note pad 18 that is struck by the player to produce a note containing the performance item; a preset pad 19 that can be set to quickly select the instrument and foot A pre-programmed configuration of pedals 2, 21 that facilitates the modulation of any of the currently played notes. 140180.doc -15· 201039339 Furthermore, the present invention selects a user input from the control and display console 23 and from various sources of the 1/〇埠 interface 5 in the additional interface section 4 in the figure. Configuration data and commands. The I/O interface 5 facilitates Mmi input, configuration data, and commands from remote sources. Such remote sources include wired or wireless river network devices such as MIDI controllers and wired or wireless business computer networks. The μι〇ι and wireless MIDI systems are included in all embodiments. In the apparatus of the present invention, each of the notes 18 has a light-emitting device that is closely adjacent to or directly attached to the note pad 18, and has a light-emitting device for each given note pad 18. The collection of light-emitting devices is hereinafter referred to as LEDA 22', which is an abbreviation for a light-emitting device array. In order to facilitate the reference in all figures, the LEDA 22 and the light-emitting device will have the same reference characters below. LEDA 22 is used to provide an indication of a note in a user selected MIDI command stream, either directly from note pad 18, from an external source, or from a source stored in the present invention. MIm song file. Leda Μ Therefore, the device of the present invention is used to promote music education. The system interface output system of the present invention is also referred to in the drawings as "Ο埠 interface 5 and includes control and display for displaying system status and configuration data, main console 23, LEDA 22, and internal sound module. 7. The external system output of the present invention is directed through a 1/() interface 5 for connection to a remote source, such as a wired or wireless midi network device, such as a MIDI sound module and a wired or wireless business computer network.

The characteristics of all of the instruments of the present invention are din standard MIDI ports for 140180.doc 16 201039339 supporting standard MIDI serial transmission protocols. However, preferred embodiments also include USB and Ethernet ports for MIDI and general interface requirements. In the main function mode, the data from the playing surface is input to section 2 and transmitted to the main operating program section 3, where the data is packaged to conform to the general MIDI specifications. This information is then transmitted to at least one of the internal sound module 7 components of 1/〇埠5, LEDA 22 or additional interface section 4 for output. The input from the note pad 18 is directed to the start note pad verification, ID and level detection procedure 9. This is a dedicated program that detects, identifies, and verifies the current note pad that has been hit by the user. The note pad 2 is identified by a unique assigned ID number as shown, for example, in Table 1. Verification including threshold detection and debounce ensures that the system is not forced to respond to counterfeit and erroneous inputs. Level detection is provided to reflect the intensity of the hitting of the note pads 18 by force or velocity sensing. The inputs from the pedals 20, 21 and the preset touchpad 19 are respectively directed to the start pedal verification and ID program 8 and to initiate the preset verification and ID program 1〇. These are dedicated programs that detect, identify, and verify actual pedals or preset inputs that have been initiated by the user. The pedal and preset input recognition is assigned to a pedal or a preset unique ID number. Includes (special) threshold detection and bounce proof. The system is not forced to respond to forgery and erroneous input. 0 Start pedal verification and ID program 8. Start preset verification and 1〇 program 1〇 and start the note pad verification. The output of the ID and level detection program 9 is transmitted to 140180.doc -17. 201039339 MIDI string builder program u. This procedure is responsible for packaging the received data into a stream of data that conforms to the general midi agreement reflecting the values and attributes of the notes that have been struck. The data stream is then transferred to the system control and configuration program 12, which routes the output to the output in the UO module 5 or to the internal synthesis program (1) to the recording and playback program 14. The user can configure the system control and configuration program 12 to route the data stream to any or all of the identified paths. The internal synthesis program 13 provides an interface between the system control and configuration program 12 and the internal sound module 7. In this regard, it is also used to manage and access the sampled sounds in the tone library 17. The mIDI data recording and playback program 14 facilitates the capture, storage and replay of MIDI sequences generated by the player. In this regard, the data recording and playing program 14 accesses the songs in the song library 15 and includes a metronome to facilitate the performance timing. Further, the present invention allows the player to download the MIDI audit file through the I/O interface 5 for storage in the song library 15. The song library 15 and the tone library 17 are divided into internal fixed memory and external removable 5 memory, which can be implemented in any of standard formats including secure digital, smart media or usb memory keys. The computer software packaged by the present invention allows the player to store the m j d j file and the tone library 17 sound file from a computer on the removable memory device. The system control and configuration program 12 is also used to set up other configurations for the present invention from the remote source including the computer network via user interaction with the control and display console 23 or via the 1/〇埠 interface 5. parameter. The system control and configuration program 12 stores these parameters in the configuration storage memory of the present invention. 140180.doc -18- 201039339 Configuration parameters include (special) musical performance parameters such as physical layout of notes on the playing surface 25, note pad 18 note configuration, note voice, APHAMS MIDI address, external device MIDI channel and plug-in Line number, ι/〇埠 selection, internal composition 13 activation, MIDI data recording and playback program 14 activation, selection of current songs in song library 15, selection of tones in internal synthesized tone library, and control and display console 23 characteristic. The midi output command stream generated by the MIDI string organizer 11 in response to a hit on a single note pad 18 is typically formed by a MIDI note open command followed by a note off command, by one of the excess methods. The MIDI note velocity data included in the MIDI note open command is determined. The preferred method uses the note pad 18 to trigger the level, which is measured as an indicator of the speed lookup table. The software implementing most of the structure of Fig. 1 also enables a large range of capabilities in the creation of sound by providing a range of algorithms used by the MIDI string builder 11. For example, 'To implement the post-touch features described in the standard midi protocol, the MIDI command stream will consist of a MIDI note-on command, which will then be followed by a MIDI post-touch command, which will usually be for each The regular interval of 100 ms is repeated 'until the crowbar or stick pressure on the note pad 18 is removed. A MIDI note off command will then be transmitted. The MIDI Post Touch command continues to communicate with the note and note velocity while the note is playing. This ability thus enhances the musical performance by allowing the player to modify the intensity of a note by changing the pressure of the stick on the note pad 18 during a stroke. 140180.doc 19 201039339 Furthermore, the apparatus of the present invention is easily implemented by enabling the large body of the structure of Fig. i to perform a single-stick and sound characteristic, and thus the selected note :^: is transmitted by multiple of the same voice or multi-speech capabilities The selection of the note composition and the generation of the sound 'and thus the selected note pad 18 triggers the generation of multiple speech in the same note. The design of the 塾 塾 18 facilitates the generation of subtle variations in pitch, thereby enhancing the second and third chords by striking different sections of the associated note pad 18. This design promotes similar features on a conventional steel drum instrument with chord tuning. Simulation 1 allows the player to emphasize the first or second overtone by striking the edges of the note area. Each of the note pads 18 is required to be provided with three individual sensors for triggering three separate MIDI commands, each corresponding to the respective notes, with each of the note pads 18 being struck by the MIDI string builder 11. Its first: with the second chord. More details of this design are explained below. The preferred embodiment of the monthly sf must satisfy a key performance goal. It must have the lowest feasible performance delay, which is defined as the primary function of the beginning of the generation of an output turbulence at the selected 1/〇璋 in response to the _trigger generated by the hit of a slap mat 18 The maximum delay. This ensures that the device of the present invention does not significantly contribute to degradation in the instant performance by adding delays present in the internal sound module 7 and to any of the external devices of the present invention. A preferred embodiment of the apparatus of the present invention as illustrated achieves the lowest feasible delay while at the same time dividing the program identified in the diagram into hardware or software implementation and interfacing the interrupt driver Maximum segmentation flexibility and user characteristics. 140180.doc -20· 201039339 Clearly, the preset verification and ID procedure is initiated because it provides the player's interface with respect to the main performance functions that require immediate detection, verification, and measurement of the hitting action on the note pad 18. 10. The start of the note pad verification, the ID and level detection procedure 9 and the start pedal verification and ID program 8 are all implemented largely by analog and digital hardware. All other programs required to generate MIDI data streams in software. Generally, then, when the player hits the note pad 18, the above-described hardware component recognizes the note pad 18, verifies the signal to eradicate the possibility of an error due to the forgery input and measures the strength of the hit. The software component is then alerted to the occurrence of a hit event by using an interrupt facility on the processing device that implements the software. These software components then input data from the hardware module to identify the hit mat and the strength of the hit. In addition to the hints of the processing device used in the apparatus of the present invention and the required timing functions, the note pad 18 and the preset pad 19 are placed with the highest priority, thus ensuring the fastest possible response to a hit event. The computational power required to implement all software programs can be implemented from an embedded processor, one of which is part of a separate hardware or FPGA or ASIC core. Digital hardware components can also be implemented on an FPGA or ASIC core. Prototypes constructed using XILINX Spartan 3 FPGAs and PIC18F6520 embedded processors have achieved latency of less than 500 ps. Depending on the full MIDI 1.0 specification published by the MIDI Manufacturers Association, the MIDI system can achieve a total MIDI delay of 3 ms or less. It is randomly learned that typical commercial MIDI controllers and composite devices have a delay of only about 5 ms, and when used with these commercial devices, the use of the pad-and-pad actually corresponds to when it is used with the 140180.doc-21 · 201039339 sample. The delay between the sonars of the present invention is a total delay of only 5.5 ms, which is substantially less than the one recommended by the full msι ms maximum of 1 cell. Now refer to Figures 2, 3, and 4 And 5, i provide a description of the physical form of the preferred embodiment of the present invention. VIII. In particular, referring to FIG. 2, which is a schematic diagram of an inner level, a preferred embodiment of the apparatus of the present invention is: ... a main physical component, U) a main assembly 24; (b) control And displaying the main console 23; and (c) mounting the bracket 27. The main assembly 24 of the device is constructed of a playing surface 25 mounted to the chassis (i.e., the main assembly chassis 26). The playing surface 25 is composed of an array of musical notes pads 18 arranged in a solid two concentric rings, each having twelve note pads 18 and having three (3) or four (sentences of rings) per array. Each note pad 18 has 2 is shown in close proximity to the note pad "or the light-emitting device 22 attached thereto, and each of the note pads 18 has a light-emitting device 22. These light-emitting devices thus constitute the LED A 22. The main assembly 24 is also used. Encapsulating the electronic circuit from the note pad _ column, the foot pedals 20, 21, the external input, and the control and display console to obtain the input and use the inputs to output the MIm output signal for the LEDA 22 and the control and display main The console 23 displays the control signal for the signal. The primary assembly 24 is also packaged - a rechargeable battery that facilitates the full 140180.doc • 22-201039339 portability of the present invention. Referring again to Figure 2, the start pedal of the present invention includes The foot pedals 20, 21 can be used to modulate the generated sound.

For this purpose, the dimensions not shown in Figure 2 are based on the ergonomic considerations of the user's height, the range, and access to the control features of the present invention (e.g., note pad 18 and control and display console 23). factor. In addition, the height of the playing surface 25 mounted on the main assembly 24 can be adjusted by minimal effort using the rotating mounting bracket to determine the (4) main assembly on the hinge 30. In addition, under the given height adjustment, the rocker/gesture lock assembly 29 shown in Fig. 4 can be used to adjust the attitude of the main assembly μ. The rocker/gesture lock assembly 29 includes a rocker arm support 34 for attaching the attitude lock 36 to the main assembly 24 through a rocker arm 45 that is packaged in the rocker/gesture lock assembly 29. The rocker arm 45 is attached to the rocker bearing 35 attached to the attitude lock main body 42, so that once the rocker arm/posture lock assembly μ is in an unlocked position, the free rotation of the main assembly 24 is promoted. The attitude lock 36 is comprised of a ratchet 37 and a pawl 38 held in a locked position by a spring 39. The support pin 40 is for attaching the spring 39 to the center of rotation of the rocker arm 41 and the attitude lock handle 43.

This allows the spring 39 to pull the pawl 38 back into its locked position against the ratchet 37. This design minimizes use during the performance The risk of accidentally releasing the locking mechanism is because the illustrated mechanism can only be unlocked by the powerful upward movement of the attitude lock handle 43. A counterweight 41 is placed on the main assembly chassis 26 closest to the player. a point to ensure that the main assembly is rotated toward the player by a preset when the rocker/gesture lock assembly 29 is released. In addition to the spring 39, this further ensures that the ratchet 37 when the mechanism is in the locked position The pawl 38 is fully engaged, thus substantially eliminating the possibility of the main assembly 24 accidentally rotating toward the player. Furthermore, although the main assembly 24 can be pushed away from the player's furthest "Hai main assembly 24" Partially rotated away from the player, but the weight 41 is reduced by ensuring that the force required is greater than the force experienced when hitting the note pad 8 positioned farthest from the player during a normal performance.

The note pad sensor 59 will also measure the impact of the hand j & The details of the note design and layout are illustrated in Figures 6 and 7. Soil; Convenient @ and based on the clarity of communication, the note pad ring is laid out and numbered from 0 to W as shown in Figure 6, where the number of tethers is. In a preferred embodiment, Nr = 3, the outermost ring is designated as the third ring 46, the inner ring is designated as the first 1% 47 of the horn, and the inner ring is designated as the second ring 48 〇 in addition to the 'notes Pad 18 carries the identification code of form Rxx, where r is the number of rings and XX is a decimal integer in the range of the two-digit digital code 'which is zero to ten (1)). In a preferred embodiment of the invention, the numbers in the digital code are sequentially incremented in a counterclockwise direction; however, the sequence can be inverted such that the code numbers increase in a counterclockwise direction. The identification number is therefore 100 to 1 U on the 0th ring 46 on the 1st ring 47 and 200 to 211 on the 2140180.doc -30-201039339 ring 48.

It should be noted that a wide range of various note pads 18 shapes and contours are possible. Figure 7a provides a top view 49 of a preferred embodiment of a note pad 18 having a curved surface contoured surface. Figures 7b and 7c respectively provide an exploded front view 50 and a bottom view 51 of the preferred embodiment. 140180.doc -31 - 201039339 The note 塾 18 is an electronic sensor 59 called a note pad sensor 59 attached to a contoured housing and uses sheets, panels, plates or thin metal blocks, plastic, others A solid composition, glass, wood or any other musical note shell 53 made of such a solid material. The note cassette housing 53 is covered on the top by the impact filter pad 54 and attached to a frame, i.e., the note pad frame 52, on the bottom. The note pad housing 53 is sufficiently thin and rigid enough to allow sufficient energy to be imparted thereto for transmission to the note pad sensor 59, which generates a trigger signal for use by the processing circuitry of the present invention described later. There is a wide range of note pad housing 53 materials and geometry and sensor technology that ensure proper and reliable triggering of the note pad sensor 59. It has been quite successful to assign 〇63 coffee/〇 25 in PVC material to the note housing 53 and to use the ceramic (four) electrical sensor for the prototype embodiment of the note pad sensor 59. A top surface of the note pad 18 is covered by a impact filter pad 54 made of a foam or rubber or another suitable compliant material. In a preferred embodiment, the material will have a Sh〇re A hardness in the range of 70 to 9 Torr and should have a thickness of only cm63 cm/〇25. The top surface will be struck with a solid crowbar to produce a portion of the note pad 18 of the tone. The manufactured impact filter pad 54 can be omitted as needed. When omitted, the tip of the playing stick or the crowbar should be covered with a suitable compliant material to minimize impact noise and damage to the surface of the note pad 18. In a preferred embodiment, the compliant material will have a Shore A hardness of between 70 and 90. Although not necessary, omitting the impact filter pad w causes 140180.doc -32-201039339 to make the invention more sensitive and particularly useful where the player wishes to play the device of the invention with a hand or finger. ❹

In a preferred embodiment of the invention, the note pad housing 53 is attached to a frame, i.e., a note pad frame 52. These frames will reinforce the note pad 18' thus increasing its resistance to deflection from sound stimuli, thus reducing the likelihood that the sensor will be inadvertently triggered in an environment with extremely high sound pressure levels. The structure of the note pad 18 and the material used for its construction must be such that the note 塾 18 when exposed to a maximum of 丨 2 〇 dBSPL (by accepting the maximum sound pressure level generally acceptable to humans) and at 15 Hz The sound level at the top edge of the device in the frequency range up to 15 Hz (typical range found in musical performances) is not triggered by external sound. The note pad frame 52 also increases the resistance of the note pad 18 to the vibrations propagated by the playing surface structure. This reduces the likelihood of crosstalk, thus inadvertently triggering the note pad 18 when striking another note 塾 or when inadvertently hitting the playing surface 25. The resistance of the note pad to structural vibration of the playing surface 25 is further reduced by using the vibration absorbing mount 55 to attach the note frame 52 to the note pad recess 33. Figure 7c also shows the note 塾 sensing (4) attached to the bottom surface of the note (4). Each of the note pads 18 can carry one or more sensors. The note pad sensors 59, such as those used on the pads, can take a variety of forms that allow for the measurement of impact force and force. Types of sensors that can be used for this purpose include eraser, Hall (HaU), strain gauges, and resistance sensors. When the (4) pressure (4) is on the note pad 18, the frequency of Hertz (DC) is returned to Kang. The 丨吴# ‘lower to 〇 The neck of the neck should be used to promote the note-lasting effect. These 140180.doc -33- 201039339 include sensors such as Hall effect sensors, strain gauge sensors, and flexible resistor sensors. These sensors have the disadvantage of requiring a DC power supply for their operation and the consequent increase in power consumption and wiring. The piezoelectric inductive detector does not respond as low as zero hertz' but has the advantage of being able to produce a high output level without the need for a DC power supply for its operation. It also has the advantage of being more responsive to fast transient effects and therefore generally better suited to speculating the impact characteristics of the strike performance. Figure 7c also shows the note pad interface electronic circuit board 6A, which is mounted to the note pad frame 52 in a preferred embodiment. The functionality of the electronic circuit interfaces the speaker pad sensors 59 to the remainder of the electronic components of the present invention to provide impedance buffering, filtering and amplification functions as needed. The design and complexity of the electronic circuit of the optional note pad 18 on the note pad interface electronic circuit board 6 will vary depending on the type of sensor used. However, the design and manufacture of such interface circuits is well known to those skilled in the art of designing electronic systems. For example, a preferred embodiment of the present invention utilizes a piezoelectric inductive detector having a note pad interface electronic circuit 60, each of which implements a field effect transistor source follower circuit for making the sensor extremely high impedance (typically up to 1 mega ohm or four) matches the low impedance input impedance of the processing circuit of the present invention described later. The source-coupling design is well known to those skilled in the art of designing electronic systems and is therefore not an inventive step. 'However, for the sake of completeness, the present circuit as shown in Figure 7d will now be described. Figure 7d shows an embodiment of a portion of the note pad interface electronic circuit 6A, a note pad sensor 59 is connected to the circuit 140180.doc-34-201039339 at the input 6〇3 and 6〇1) to the terminal Buffered output is produced at 60f and 60g. The circuit uses a single-low steam leak (four) 6 〇e, such as 4117 swollen τ, in the source configuration. The open-pole resistor 60d biases the gate at the ground potential, and the quiescent current flowing through the source resistor 6〇e biases the source above the ground, thereby establishing the reverse gate source bias required for linear operation. Pressure. The voltage fluctuations at the input terminals 60a and 6G are shown at the same level at the output terminals 60*> and 60§, thus giving a circuit gain. However, since the source resistor 6〇e has a value of typically only a few thousand 〇 35 ohms, much less than the resistance of the gate resistor 60d which would normally be in the range of 20 mega ohms to 100 mega ohms, the output The impedance system is much smaller than the typical values specified for piezoelectric sensors. The circuit is powered by a positive DC supply applied to terminal 60h. Referring now again to Figure -, there is shown a top view of a preferred embodiment of the mattress 18 as seen by the player. The note pad 18 incorporates an array of hit zones to create a more practical effect, and when the different portions of the note 塾 18 are struck, the timbre of the note produced by the timbre pad 18 is slightly altered. In a preferred embodiment of the invention, three hit zones are used to implement this variable timbre characteristic. Figure 7a shows the location of the striking zones 56 57, 58 on a preferred embodiment of a note pad 18. It should be noted that in the apparatus of the present invention, the striking area is not clearly visible and the area in Figure 7a is labeled only for purposes of discussion. The sensor system in the primary hitting zone 56 is placed at the center of the note pad 18. The remaining hit zones are referred to as secondary hit zones 57, 58 which are comprised of circumferential strike zones 57 and U strike zones 58. The sensor on the circumferential hit zone is along the extreme placement of 140180.doc -35-201039339 = 垫 cushion 18 which is closest to concentric circles that limit the magnetic domain in which the note pad 18 is placed. Sensing on the radial striking zone 58: is placed along the extremes of the note 塾 18, which is closest to the radial line that limits the annular magnetic field in which the note pad 18 is placed. The present invention is by hitting The note pad 18 is characterized in that the main hit _, the circumferential hit area 57 and the radial hit area 58 are regarded as a separate note of a three-note polyphonic performance, and a variable timbre characteristic is implemented. The change in tone experienced in the drum, the sensor in the primary hit zone 56 is used to trigger the note assigned to the note 18 and the sensor in the circumferential hit zone 57 is used to trigger the assignment. A note of one octave above the note of the note 并且 18 and the sensor in the radial hit zone 58 is used to trigger a note assigned to the octave above the fifth note above the note of the note pad U. The note that is assigned an octave above the fifth note above the note of the note 塾18 The fundamental frequency corresponds to the third chord assigned to the note of the note 塾 18. The variable timbre option affects the design of the note pad interface electronic circuit 6 . In particular, the note pad interface electronic circuit 6 〇 must now and Into the three separate sub-circuits as shown in Figure ,, a separate sub-circuit is used for each of the hitting zones 56, 57, 58. The circuit shown in Figure 现在 will now be connected at the wheels 60a and 60b. One of the note pad interface electronic circuits 60 in parallel to one of the note pad sensors 59 or one of the note pad sensors 59 in a single hit zone 56, 57, 58 to produce a portion corresponding to the terminal 6 Three independent buffered outputs of 〇f and 6〇g. The configuration and implementation of the illustrated embodiment are triggered by the sensors in the circumferential hitting zone 57 and the sensors in the radial striking zone 58. The level of each of the notes 140180.doc • 36- 201039339 will vary depending on the actual position of the hit on the associated note pad 18. However, the essence of the sound triggered by the primary sensor 27 is always dominated by To hit the sound of the sensor in zones 28, 29. The remaining method poems are up to the primary sensor 27 by appropriate installation, or by the attenuation of the resulting electronic signals, including the sensors in the secondary hit zones 28, 29. The entity in the sensitivity is reduced. In a more advanced embodiment, the actual hit position can be estimated from the output of the various sensors on the note pad 18 and this information is used to determine the note. The relative level of the polyphonic music component triggered by pad 18. The fuzzy logic algorithm can be used to facilitate embodiments of the method. In a preferred embodiment of the apparatus of the present invention, two uses are implemented by the operating software. Adjust the parameters to get the dominance of the sonar triggered by the main sense (four). The first parameter is the Secondary Sensor Attenuation Factor (SSAF), which is applied to the king domain variable of the trigger level measured from the sensors in the secondary hit zones 57,58. The second parameter is the maximum secondary sensor velocity (Mssv), Ο which specifies the maximum of the octave and the third chord note triggered by the sensor in the secondary hit zones 57, 58]^11) 1 note Speed, as a small part of the midi note strength of the notes produced by the main hit zone %. The operating software in the apparatus of the present invention measures the output of two sets of sensors in the secondary hitting zones 57,58. If the sensor output levels of the two zones are within ten to thirty of each other, the storage variables corresponding to each of the sensor output values are zeroed and thus valid The variable timbre effect is suppressed. Otherwise, the storage variable corresponding to the sensor with the smaller output value is zeroed. This method ensures that if the secondary sensors receive a roughly equal amount of energy from the stick impact of 140180.doc -37· 201039339, the localized variable timbre effect is immediately adjacent to the 'human hit zone 57, 58'. 'Does not play any of the notes triggered by the two sets of sensors. It also ensures that only one of the notes triggered by the two sets of sensors in the secondary hit zones 57, 58 is generated. The secondary sensor output value is then multiplied by the SSAF and the corresponding MIDI speed determined. At the same time, the MIDI strength of the notes produced by the main hit zone 56 sensor is determined. If the MIDI strength of any of the notes triggered by the secondary hit zone 57, 58 sensor is greater than the MSSV multiplied by the strength of the suffix of the lx by the main hit zone 56, then it is automatically limited to borrow The value obtained by multiplying the MSSV by the force of the main hit zone 56 sensor. The variable timbre characteristics are automatically deactivated for all note pads assigned to percussion speech (eg, drums and cymbals) and for effects. Although the variable timbre characteristics are aimed at more advanced users, they are also beneficial to all players because the pitch changes create a more natural environment by more closely simulating the feel of a traditional acoustic steel pan. When the speech other than the steel drum is selected, the contents of the various hitting zones 56, 57, 58 also improve the natural characteristics of a performance. The note pads 18 can be of any size, shape or color. However, for the reasons explained below, preferred embodiments of the present invention assign physical attributes of size, shape and color to assist the player in distinguishing the notes on the playing surface 25. In this regard, it should be noted that since the linear configuration of the notes on a music keyboard (eg, a piano) allows easy distinguishing and recognition of notes, this is not a concentric circular approach obtained with the current device as in 140180.doc • 38· 201039339. The situation when placing notes. If the beginning or end of a particular ring cannot be quickly distinguished, the circular layout makes it difficult to quickly identify the note. Moreover, as seen in Figure 6, the circumference of the ring decreases as one note moves toward the center of the playing surface 25, thereby forcing the size of the note pad 18 to advance from the second ring 46 through the first ring 47 with a note. It decreases to the inner ring second ring 48. All of the note pads 18 used on the device of the present invention may be of the same size; however, preferred embodiments use variations in the combination of shape, color and size of the note pads 18 to provide visual cues to eliminate when a steel The drum player must quickly recognize the confusion that occurs when the notes are laid out in a circular manner. As is found on conventional acoustic steel drums, variations in the surface area of the note pads 18 in accordance with the pitch of the notes are used to provide visual indication of the assigned notes to the player. Thus, the note pads 18 associated with the lower frequency notes are greater in size than the note pads assigned to the higher frequency notes. Due to the electronic features of the present invention, it is not necessary to accurately calculate the note size of the note pads 18, which is the case with conventional steel drums. Furthermore, by dividing one octave into an integer of one of the different semitone stacks, the number of size changes can be substantially reduced, thereby reducing manufacturing costs. For the purposes of this document, the tone stack is defined as a group of notes that form an adjacent subset of one of the chromatic scales. A single note size can then be assigned to each semitone stack. The number of semitone stacks required for efficient application of the provision of visual cues for note recognition depends on the actual note layout used. The half note layouts that need to be assigned to the semitone adjacent notes should also be 140180.doc -39· 201039339 The physical proximity 'except at the beginning and end of each ring with the digital code zero (00) and eleven ( 11) other than the note pad 18. As such, the semitone layout absolutely requires a minimum of twelve different note pads 18 size. In practice, you will need up to twenty-six different sizes to implement all three octaves. On the other hand, 'tests have shown that a layout based on a loop of four (3) semitone stacks of four (4) notes using a fourth and fifth notes of music (preset on the current invention) can be effectively used. Less than three (3) notes pad 丨 8 size. The effectiveness of this method is due to the fact that the two adjacent musical note pads 18 will not have the same size. In this regard, on any given ring, all of the note pads 18 assigned to the notes C, C#, D, and Eb are assigned a maximum size, and the note pads 18 assigned to the notes E, F, F, and G will have a common comparison. Small size, and the note pads assigned to notes G#, A, Bb, and B "will have a common minimum size. The physical shape of the note pads 18 can be changed to further increase the size change strategy to assist in day 4 recognition. On the one hand, the successful application of the strategy would require that two adjacent notes 塾 18 in the same ring would not have the same shape. More than twelve (12) different shapes would then be used for this purpose. Then, a smaller number of differences could be used A note recognition of the same degree of shape thus promotes a k ^ column at a lower cost. For example, two (7) different shapes can alternate as a note advances around a given ring. Or, as illustrated by the strategy for size changes A unique shape can be assigned to each semitone stack, resulting in exactly three different shapes for each ring as shown in Figure 6. In addition, 'can be used by a barbaric & / 匕 color /shadow The scheme is to increase the size change and shape change strategy for the notes 140180.doc •40· 201039339. The most logical color scheme will take advantage of the higher pitch of the notes. A unique color/shadow combination. This method can be applied to the full 邛 character on APHAMS, in which case requires a minimum of 36 color/shadow combinations; or applied to a single ring with a color pattern repeated over all rings, In this case only twelve color/shadow combinations will be required. The alternative would need to assign a unique color to any given semitone.

All the notes in the heap, rather than individual notes, resulting in a minimum of three colors in the case of repeating the same color scheme on all rings and applying different color schemes to each of the three rings of the preferred implementation Up to nine different colors. The preferred embodiment of the present invention utilizes the note 实体 18 entity attribute to provide a prompt for note differentiation on the view, as explained below and as shown in Figures 6 and 2. Use a #四度& fifth note 4 circle to assign notes to the stomach and other notes 塾 is. The notes are grouped in three semitone stacks identified as cco, CC1, and cc2 based on convenience. In each ring, 'four notes c, c#, 〇 and 0 are assigned to CC0, and the next four notes E, 卜 and 〇 are assigned to (10) ^ 4 t @ t | (four) notes 'A, ^ and transfer assignment To CC2. These notes are assigned to notes (4) as detailed in Table 2. The same semitone stack identifier is applied to all rings. The same unique entity properties of shape and color are applied—given a semitone stack CC0, CC1, or CC2, regardless of the actual ring position. In addition, all four note pads (4) associated with a note in any given semitone stack have the same unique entity properties as the shape, size, and color associated with the 140180.doc -41 - 201039339 semitone stack. However, on any given ring, each semitone stack has its unique and different size attributes' size monotonically decreasing from CC0 through CC1 to CC2. Moreover, for any given semitone stack, the size monotonically decreases from the second loop 46 to the second loop 48.

These pictures are movable, thus facilitating the user to assign the percussion instrument to the sound (4) 18 The flexibility of the preferred embodiment of the main assembly electronic circuit 3! of the device of the present invention is now described with reference to Figure 8'. Representing data transformation procedures, The edge rectangle represents the data storage area and is closed and rectangular by the input and output interfaces. The Ge table indicates the data movement by the arrow. Because Figure 8 is a high-level representation of an electronic circuit, it also represents the critical control information. In this regard, The figure is slightly less than the Gane-Sarson convention. Although Figure 8 is somewhat unfamiliar in its explanation of an electronic circuit, 140180.doc -43- 201039339 provides an electronic hard of the present invention that is far less confusing than conventional electronic circuit diagrams. The disclosure of the various blocks in Figure 8 is not representative of the inventive steps and is known to those skilled in the art. The main assembly electronic circuit 31 provides the following functions: (1) 塾 signal chopping to eliminate the note pad 18 Array and the wrong output of pedals 2, 21, (2) Instantly identify the pad number of the note pad 18 that was hit, ("immediately measure the force used to hit the identified pad, (4) instant mapping The pad number of the activated note pad ^ to the user-programmable feature associated with the identified pad - list '(5) is required for the output (4) to stream, ("transfer milk to flow, (?) 0 activates LEDA 22, (8) interfaces with control and display console 23, and (9) functions for proper operation of the overall system management function of the apparatus of the present invention. The main assembly electronic circuit 31 of the present invention is mainly The assembly interface circuit 63, the main assembly embedded processor 68, the system memory 71, the internal synthesizer 69, and the internal synthesizer 69, all of the memory elements required for system operation except the tone library memory 7 are at the highest level. SUMMARY OF THE INVENTION The tone library memory 7A of the tone library s-recovery module 17 and the external interface module 72 are fully realized in Fig. 1. The main assembly interface circuit 63 provides the tone for the self-playing surface 25. The input adjustment signal of pad 18, preset pad 19 and pedals 2, 21 and provides the resulting adjustment signal as input to main assembly embedded processor 68. The above signal adjustment function will be described in more detail below. The main assembly hin-in processor 68 also takes input from the MIDI wireless and cable and control and display consoles 23 to generate MIDI wireless and wired output signals, visual feedback system signals to LEDA 22, and control and display masters. Console 23 shows 140180.doc -44 - 201039339 signal. The output of the note pad interface electronic circuit (9) positioned on each of the note pads 18 is directly connected to the main assembly electronics 31 using a removable connector, thereby facilitating replacement and repair of the individual note pads 18. The connection is made directly to the peak detector and trigger module 33 of the main assembly electronics circuit 31. The peak detector and flip-flop circuit 61 takes input from the sensor on the note pad 8 and outputs: a trigger pulse that is fed to the bounce and blanking logic module 62 trigger pulse to indicate that The associated pad; 〇 and the peak of the signal level are input to an analog to digital converter array (ADC array) 64 to provide an indication of the impact force of the hit on the associated note pad 18. There are three peak detector and flip-flop circuits 61 for each of the note pads 18, one for each of the primary hitting zone 56, the circumferential hitting zone 57, and the radial hitting zone 58. Each group of sensors. Figure 9 shows a schematic diagram of a circuit that can be used to implement a peak detector and flip-flop circuit 6i, which is designed and operated by those skilled in the electronics arts. One of the three outputs of the note pad interface electronic circuit 60 positioned on each of the note pads 18 is coupled to the input terminal 61a, 611^ and the positive voltage across the note pad interface electronic circuit 60 is transmitted through the diode. 61 g of charging capacitor 611. The diode 61g ensures that the charge thus stored in the capacitor 61i does not flow in the opposite direction when the voltage on the input source drops to the voltage on the capacitor 61i, i.e., flows back to the input source. Or it ensures that the negative voltage generated by the note pad does not discharge the capacitor 6U. Diode and Power 140180.doc -45- 201039339 The series combination of the bar 611 thus ensures that the capacitor is charged to the peak input voltage. Resistor 61h ensures that the capacitor is discharged by a blow below the note. The value of this resistor is chosen such that the capacitor is fully discharged within 50 ms, thus allowing the detector to intercept the peak value of the hit occurring at a rate of up to 2 hits per second, which is known as It is larger than the faster measurement speed that the drummer can roll. The 5 〇 ms period also allows for sufficient time to convert the analog peak value to its number (four) effect. This peak value is output across the terminals 61c, 61d. Therefore, it should be understood that in the normal performance (4) t, (10) the heart hits the note 四 (4) The appliance is lifted immediately after the impact, and the note 塾 18 will produce a damped echo response to a single hit. This output can also be generated by the natural tendency of the appliance to bounce on the surface of the note (4) immediately after the first impact. The money understands that (4) in the (4) material, the money user will try to keep the performance instrument against the note pad 18 after the first impact. In this case, the output response will be a single-transient pulse. ^ The minimum delay between the (4)-impact and the generation of the peak force representing the peak detection and the impact at the output of the flip-flop circuit , is connected to the peak Detector with the sensor Μ on the HI (four) note pad 18. Measure and touch circuit 61 to ensure that the first peak in the round-trip response is always positive = pure. In the specific embodiment, the material and structure of the note 塾u must be only 25 milliseconds after a stick impact In addition, the output return value of the pair-single-striking should be separated by only 2 〇 milliseconds. Select this as specified; time two 140I80.doc -46 - 201039339 to protect the player 20 times per second Each hit is measured at the rate of the hit or at a rate below it, and the rate is known to exceed the maximum measured scroll rate by the professional drummer. Capacitor 6K and Series Resistance The device 61j forms a high-pass chopper that emphasizes a significant transient phenomenon in the input signal caused by the striking on the note pad 18. The filtered signal is input to one of the arms of a comparator 61m, which will be borrowed. A spacer formed by a resistor 61LA61k A reference voltage generated by the chain exerts a force on the other input. The money is compared with the 11 output, so a positive pulse is generated when the chop input value exceeds the reference value. The trigger pulse is output across the terminals 61e and 61d. Both the flip-flop and the peak detection sub-circuit of the flip-flop circuit 61 are used for the sensors in the main hitting area 56. For the sensors in the secondary hitting areas 57, 58, no peak detection is used. The flip-flop circuit of the flip-flop circuit w. However, the peak detector circuit of the peak detector and flip-flop circuit 61 is used to indicate the excitation of the output of the sensor when the note pad 18 is struck. The anti-bounce and blanking logic module 62 is used to verify the occurrence of a hit by eliminating the above-mentioned parasitic effects of the plurality of pulses generated by the sensor in response to a single hit. In the absence of bounce and blanking logic 62, these multiple pulses can be easily interpreted erroneously as a multi-hit by the fast processing electronics in the main assembly electronics 31. This module is not a sensor Required (such as Hall effect sensors), etc. The intrinsic characteristics of the sensor are anti-bounce capability but will still function if this switching technique is used. The output of the bounce and blanking logic 62 is fed to the encoder logic module 66' which encodes the associated pad number to Input to the main assembly embedded processor 140180.doc -47- 201039339 68 〇In the 塾 number encoding, the output is triggered by the bounce and blanking logic 62 - triggering the physics U to the ADC selection and trigger logic module 65. The module outputs a signal to begin the data conversion process in the ADC array 64. The array contains - ADC 'which will be selected by the bounce and blanking logic Q to convert the analog value of the height of the bee to a digit. The information is encoded in the data output of the ADC in the ADC array 64 to be input to the main | accessory embedded in the 68 〇 interrupt generator logic 67 monitors all analogy to digital conversion in the ADC array 64 to complete its individual The data conversion loop and sends a key to the main assembly sink 68 to access the _ code of the note pad 18 struck from the output of the encoder logic module and from the analog to analog conversion of the ADC array Reads the corresponding digital word represents the strength of the value of hitting. The t-break generator logic 67 takes the output flag from the analog-to-digital converter of the ADC array to the output flag and generates an interrupt request for the main assembly embedded in the 2 processor 68. The processor is programmed to identify the mat 18, the preset pad 19 or the activated pedals 2, n and read the value corresponding to the note value of the note pad 18 or the pedal 2 (), as needed, 2] The data value of the output. After the main assembly embedded processor 68 reads the selected analog output in the ADC array 64, the output of the digital converter, it transmits an acknowledgment to the interrupt generator logic 67, which then clears the analog to digital bits in the ADC array material. The conversion of the converter ends with the input of the dj flag. It then passes through the transmissive interface module 72 to relay MIDI commands to the appropriately configured MIDI device connected to the ί/O埠 interface 5. 140180.doc -48- 201039339 In a preferred embodiment of the device of the present month, the interface 5 will implement a wired MIDI output port and a MIDI wireless port. The Mim stream can also be directed to an internal synthesis module 69 by means of a titanium quasi-removable memory (such as a Secure Digital (SD) or Smart Media (SM) card) or in a USB The implementation of the tone library memory on the memory key is promoted. The 1/0埠5 of the present invention supports the connection of external devices using standard MIDI, USB, Firewire 'Ethernet protocols. There are also wireless MIDI features. These intrinsic features not only allow the milk to have the best flexibility in communication, but also facilitate the downloading of performance materials including MIDI sequences and tone libraries, software for the tour performers and upgrades. In particular, the latter facility allows the device of the present invention to be adapted to a new MIDI^ as it is disclosed by the Association of Manufacturers. In addition to minor changes, the main assembly is embedded in the processor _ class (4) The manner of the note pad 18 is operated on the input from the pedals 2, 21. In particular, for pedals 20, 21 having a continuous analog output, the outputs are directly routed to an analog to digital converter in ADC array 64. This will be applied, for example, to a pedal 20 ' 2 that is capable of such a round trip and configured as a volume control. In addition, the peak detector and flip-flop module 61 are replaced by a non-inverting single gain buffer. A peak predator circuit designed to be known to those skilled in the art of electronic design. The output of this buffer is coupled to whip array 64 to provide an indication of pedal activation when pedals 2, 21 are used as volume control or - pitch wheels. The trigger circuit of the peak_device and flip-flop module 61 140180.doc -49- 201039339 provides a trigger readout that is sent when the pedal edge passes through its predetermined reference point. This point is determined by the reference value set by the network of the resolver formed by the resistors 6ik, 6u in Fig. 9. In addition to the change, the main assembly embedded processor is operated on the preset (6) 9 in the manner of the notes (4). There is neither a connection of the prison array 64 nor a peak (four) detector and trigger. Except for the module μ peak programming circuit. Only the flip-flop circuit of the peak price detector and the flip-flop mode (4) is utilized to indicate the occurrence of a predetermined pad 19 hit. The LEDa 22 is driven by the LEDA control module 73, which will treat the _m data stream as its input by the main assembly embedded processor 68. The note information from the MIDI stream and the mapping of these notes! The user-programmed configuration of the note pads 18 of the 8 to notes determines the selection of a particular light-emitting device in the LEDA 22 to be activated. The source of the secondary source can be internal, such as by the note pad 18 when in the diagnostic mode; or external, such as when in the teach mode, by another MIDI device on the wired or wireless Mim network. produce. The logic modules in the main assembly interface circuit 63 can be implemented using any available digital electronics technology, including field programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), or embedded processors.

The highest level of Fig. 1 is 140180.doc • 51 · 201039339 The tone library memory i 7 and the song library memory 丨 5 shown in Fig. 1 are directly implemented in the assembly embedded processor software DFD 46 of Fig. 10. The tone library memory 70 and the song library memory 82. The performance surface interrupt handler program 75 is initiated by the interrupt generator logic 67 in the main assembly electronics circuit 31. This is the availability of new information from the note pads 18 or preset pads 19 on the playing surface 25. When receiving the interrupt, the performance surface interrupt handler program 75 uses the material presented by the encoder logic 66 to identify the source of the interrupt as the preset pad 19 or the note pad 18. The use of interrupts facilitates rapid and reliable capture and handling of pad hitting events. If the source of the interrupt is identified as the preset pad 9, the number of the pad to be activated is obtained from the preset number data output from the encoder 38. If the source of the interruption is identified as the note pad 18, the performance surface interrupt processor 75 identifies the note struck by reading the note pad number data output from the encoder logic 66 in the main assembly electronic circuit 3A. . It then samples the note level by reading the output of the ADC array 64. It then obtains the number of any of the pedals 2, 21 depressed by the numbering of the pedals 20, 21 output from the encoder 38 in the main assembly electronics 31. Finally, it reads the output of the secondary sensor in the associated note pad 18 corresponding to the circumferential striking zone 57 and the radial striking zone 58. This - all of the material is then communicated to the [11] 1 command generator program 79. The MIDI command generator 79 constructs the MIDI command data stream based on the information received from the performance surface interrupt processor 75 using the current configuration data in the note pad configuration memory 78. The data in this area is configured as a programmable moment 140180.doc -52- 201039339 array, which maps each note pad 18 to the user-specified assignment of note properties, including (special) notes, speech, MIDI channels, SSAF and MSSV. The capabilities such as variable timbre, chord and multi-speech settings are also accommodated in MIDI command generator 79. The note pad configuration storage memory 78 accepts data from the preset loader program 77 or the system control program 86. The system control program 86 stores the data in the note pad configuration storage memory 78 based on user input from the control and display console. It also populates the preset configuration memory 76 with preset configuration data for each number as determined by the user. The preset loader program 77 is responsible for capturing the note pad 18 data stored in the preset configuration memory 76 corresponding to the preset number information transmitted from the performance surface interrupt processor 75 and writing the data to the note pad set. State memory 78. This facilitates automatic and dynamic reconfiguration of the system. The MIDI command data stream is then forwarded to the I/O interface program 87, which transmits the MIDI commands through one or more channels in the I/O interface 5. The role of the I/O interface program 87 is to format the MIDI stream for transmission through any output channel selected by the user. The MIDI output from the I/O interface program 87 can also be directed to the internal synthesis program 88, or the LEDA controller program 84. The I/O interface program 87 uses the I/O port configuration memory 83 to identify the MIDI input and MIDI output channel number selected by the user and to determine whether the internal synthesizer 69 and/or LEDA 22 will be deactivated. The LEDA controller 84 program is responsible for controlling the on/off state of each of the light emitting devices 22 on the playing surface 25. It accepts input from the playing surface 25 or from the current MIDI input port through the I/O interface program 87. The LEDA control 140180.doc -53- 201039339 obtains its operational status from the system setting memory 85. This status includes the status of the direct action, on or off, whether it is in the teach or diagnostic mode, and the source of the MIDI stream as an internal or external source via tMim埠. The system control program 86 uses the control console menu manager' to input and display the current configuration settings of the present invention. The control console menu manager program 89 controls the interactive display and user input on the control and display console 23. In a preferred embodiment of the invention, the user interface implements a page-based menu structure, as explained below. The recording and playing program 81 stores the stream of the stream when it is started by the user together with the time stamp information of the MIDI timer program 80 in the song library 82. The songs stored in the song library 82 can be retrieved by the recording and playback program 81 for playback by the I/O interface program 87. The 1/〇 interface program 87 can also mix the playback MIDn4 of the self-recording and playback program 81 with the new stream data generated by the user from the note pad 18 on the performance surface 25. This allows the performer to drop, for example, a tap track that can then be re-played as a accompaniment. The MIDI Timer Program 8 is also used to implement the metronome feature through the internal synthesis program 88. The record and play program 81 is also used to retrieve the rhythm midi sequence from the song library 82. In this regard, the song library 82 is divided into four segments (a) a user-programmable song store that facilitates storage of user-generated or user-downloaded sequences as described above; (b) user-programmable a rhythm storage device that similarly operates as a user-programmable song storage section but is explicitly identified for the rhythm pattern; (C) APHAMS song storage, where the predetermined 140180.doc • 54-201039339 semantic sequence is stored And it cannot be erased by the user and

The lowest note is C and is placed on note pad 000. This allows the invention to be quickly configured for sound steel drum simulation and synthesis. A sound steel drum with a similar range is somewhat different in the resulting tone. 140180.doc -57· 201039339 For example, a mid-range bass does not emphasize the lower overtone as much as the six (6) bass used to make a note on two instruments. It should therefore be confirmed that the synthesis of traditional instruments will have some drawbacks when using the same MIDI voice for the full range. In a preferred embodiment, this problem is solved by accurate internal synthesis of each steel drum instrument or by using sampling characteristics available in many commercial MIDI synthesizers. Selection of Drum Function Table The present invention configures the present invention to transmit commands on a channel 10 assigned for a general MIDI drum. The preferred embodiment assigns a note pad for the drum/striker, as shown in FIG. The user can also use the voice menu to directly type in the MIDI code, allowing the user to use a MIDI device with a different mapping than the GM patch map. Many MIDI sound modules will need to be accessed by specifying the relevant MIDI library number; the user can do this through the MIDI sub-menu item under the System Configuration menu.
