Description

  The present invention relates to an electronic musical instrument and a method for controlling the electronic musical instrument, and in particular, a technique suitable for use in order to facilitate maintenance and management in accordance with the type of waveform memory provided in the electronic musical instrument. About.

  Electronic musical instruments usually have a waveform memory for storing digital data (waveform data) representing musical sound waveforms, and the specified waveform data is read from the waveform memory, and an interpolation operation for pitch conversion is performed as necessary. A sound source circuit that performs processing, envelope processing, filtering processing, and the like is provided.

  The waveform data read from the waveform memory is subjected to various types of processing as necessary, then converted into an analog signal (musical sound signal) representing a musical sound waveform, and the musical sound is transmitted via a sound system including an amplifier and a speaker. Sound is released into the space.

  Electronic musical instruments are usually provided with a timbre designator for designating timbres, and which timbre designation operation determines which waveform data is read out by the sound source and what processing is performed on the read waveform data. It is specified by timbre data corresponding to the operation of the child, performance data representing the performance operation, or the like.

  For example, when a keyboard is provided on the electronic musical instrument, the performance data is generated by a performance operation of the keyboard. For example, it may be input from the outside as MIDI data. Alternatively, for example, performance data for one song may be arranged and stored together with time data, and the performance data may be read according to the time data. An array of performance data stored together with time data is called sequence data.

  For example, patch data may be associated with each key of the keyboard or performance data input from the outside. Here, data for generating a musical tone in an electronic musical instrument such as the waveform data, performance data, sequence data, and patch data is generically referred to as “musical sound data”.

  In the electronic musical instrument, for example, musical tone data is added to add a timbre or increase the number of musical pieces for upgrading. In addition, a so-called version upgrade, in which a program is added to improve the operability of the electronic musical instrument, may be performed.

  When adding or changing a program, the program is loaded into a rewritable program ROM or the like provided in the electronic musical instrument main body. There are usually two ways to update a program. The first method is a method of rewriting the stored contents of the rewritable program ROM through a predetermined procedure such as inserting a memory (ROM) card or the like into which new program data has been written into a card slot or the like and then turning on the power. is there.

  Further, the second method of program update is to introduce (load) MIDI (Music Instrument Digital Interface) data representing a new upgraded program into a rewritable ROM via the MIDI terminal of the electronic musical instrument main body, and to update the old version. This method is to discard the program and write a new version of the program.

  As described above, a method for writing a new version of a program has been proposed by, for example, an electronic music apparatus described in Patent Document 1. The electronic music apparatus described in Patent Literature 1 stores a CPU having unique identification information, CPU identification information acquisition means for acquiring the identification information of the CPU, and the acquired identification information of the CPU as electronic music apparatus identification information. Storage means for transmitting, transmitting means for transmitting the stored electronic music device identification information to a server via a network, and receiving means for receiving content including the transmitted electronic music device identification information from the server. ing.

(First embodiment)
Next, embodiments of the electronic musical instrument of the present invention will be described with reference to the drawings.
As shown in FIG. 1, in this embodiment, a common program is loaded to one electronic musical instrument 100 in which the waveform memory A106 is disposed and the other electronic musical instrument 200 in which the waveform memory B206 is disposed. In this example, the electronic musical instruments 100 and 200 can be operated without error.

  One electronic musical instrument 100 is provided with an input terminal 101, a MIDI interface (I / F) 102, a CPU 103, a program memory 104, and the like. In the book, the patch data is stored in the program memory 104, but the patch data may be stored in the waveform memory A106. The patch data is a set of parameters such as tone color and volume that define one musical tone.

  In addition, a RAM (work memory) 105, a waveform memory A106, a tone generator LSI 107 constituting a tone generator unit of one electronic musical instrument 100, a display device 108, a DAC (digital / analog converter) 109, an amplifier 110, and an output terminal (OUTPUT) 111 Etc. are arranged.

  The other electronic musical instrument 200 has the same configuration as the one electronic musical instrument 100, and is provided with an input terminal 201, a MIDI interface (I / F) 202, a CPU 203, a program memory 204, and the like.

  Further, a RAM (work memory) 205, a waveform memory B 206, a tone generator LSI 207, a display device 208, a DAC (digital / analog converter) 209, an amplifier 210, an output terminal (OUTPUT) 211, and the like are arranged. In the other electronic musical instrument 200, patch data is arranged in the waveform memory B206.

  One electronic musical instrument 100 and the other electronic musical instrument 200 configured as described above operate according to programs supplied from the outside and written in the program memories 104 and 204.

Next, the operation of the electronic musical instrument 100 (200) of the present embodiment configured as described above will be described with reference to the flowchart of FIG.
As shown in FIG. 2, when the operation is started, the ROM ID is read in the first step S21.

  As shown in FIG. 3, the ROM ID is read by reading data stored at the final address “03FFFFFF0” of the waveform ROM (waveform memory A106, waveform memory B206). Note that the waveform ROM having a capacity less than the final address “03FFFFF0” is a ROM that is not a target in the present embodiment. Further, when specifying the type of the waveform memory, it is not necessarily limited to reading the data of the final address “03FFFFF0”. In each waveform memory A106 and waveform memory B206, the type of the waveform memory may be specified by reading the information of the address where the unique waveform data is stored.

  As described above, the ROM ID is specified to recognize the type of waveform memory provided in the electronic musical instrument. In this embodiment, one electronic musical instrument 100 is provided with a waveform memory A106, and the other electronic musical instrument 200 is provided with a waveform memory B206. The waveform memory A106 and the waveform memory B206 differ in the type of waveform, the number of waveforms, the address, and the like. The waveform A address table and patch data are stored in the program memory 104, and the waveform B address table and patch data are stored in the waveform memory B206.

As shown in the address explanatory diagram of FIG. 3, in this embodiment, “ROM ID” is stored in the last 16 bytes of the waveform memory.
In the case of the device A as the “ROM ID”, “ROM ID = 01234”, 0xAA, 0x55, 0xAA, 0x55 ”(52, 4F, 4D, 20, 49, 44, 3D, 30, 31, 32, 33, 34, AA, 55, AA, 55 "are recorded.

  In the case of device B, “ROM ID = 56789”, 0xAA, 0x55, 0xAA, 0x55 ”(52, 4F, 4D, 20, 49, 44, 4D, 35, 36, 37, 38, 39, AA, 55, AA, 55) are recorded.

  When the ROM ID is read in step S21, the process proceeds to step S22 to determine whether or not “ID = Device A”. If it is determined that “ID = Device A”, the process proceeds to step S23. If “ID = Device A” is not satisfied, the process proceeds to step S24.

In step S23, the address table and patch data A stored in the program memory 104 are loaded into the RAM 105. If the process proceeds to step S 24, the address table and patch data B stored in the waveform memory B 206 are loaded into the RAM 205.
Next, the process proceeds to step S25, and initialization processing of other performance information generation operations is performed.

  In step S26, keyboard scanning is performed. Thereafter, in step S27, it is determined whether a key event has occurred due to a keyboard scan. As a result of the determination in step S27, if there is a keyboard event, the process proceeds to step S28, where the waveform is read based on the address table and patch data loaded in the RAM 105 (205), and the sound generation process or the mute process is performed. When these processes are completed, the process proceeds to step S29, where the panel switch SW is scanned. If the result of determination in step S27 is that there is no keyboard event, the process proceeds directly to step S29.

  When the panel switch SW scanning process in step S29 is completed, the process proceeds to step S30 to determine whether there is an event. As a result of the determination, if there is an event, the process proceeds to step S31, and it is determined whether or not the generated event is an event related to the menu switch.

  If it is determined in step S31 that the event is related to the menu switch, the process proceeds to step S32, and it is determined whether or not “ID = Device A”. As a result of this determination, if “ID = Device A”, the process proceeds to step S33, and if not “ID = Device A”, the process proceeds to step S34.

  In step S33, the parameter corresponding to “waveform A” stored in the waveform memory A106 is displayed on the display device 108. FIG. 4A shows a display example of parameters corresponding to “waveform A”. In the present embodiment, as parameters corresponding to “waveform A”, “1. Sound = Grand Pian”, “2. Damper Effect = 5”, “3. Attack = + 0”, “4. Decay == + 0”. , “5. Release = + 0” is displayed. In FIG. 4A, “Damper Effect” is to adjust the amount by which the resonance effect when the damper pedal is depressed is added by a DSP (Digital Sound Processor).

  In step S 34, the parameter corresponding to “waveform B” stored in the waveform memory B 206 is displayed on the display device 208. FIG. 4B shows a display example of parameters corresponding to “waveform B”. In the present embodiment, as parameters corresponding to “waveform B”, “1. Sound = Grand Piano”, “2. Damper Resonance = 5”, “3. StringResonance = 5”, “4. KeyOffResonance = 5”, “4. 5 shows an example in which “Attach = + 0”, “6. Decay == + 0”, “7. Release = + 0”, and the like are displayed.

  In the present embodiment, the waveform memory B206 includes waveform data that was not in the waveform memory A106. Accordingly, functions that could not be realized by one electronic musical instrument 100 can be realized by the other electronic musical instrument 200. As an example, the menu display of “1. Sound = Grand Piano”, “2. Damper Resonance = 5”, “3. String Resonance = 5”, “4. Key Off Resonance = 5” is shown in FIG. Is displayed. “Damper Resonance” is a function for adjusting the volume of the resonance sound when the damper pedal is depressed. “String Resonance” is a function for adjusting the volume of resonance sound between the strings of the keyboard being pressed. Furthermore, “KeyOffResonance” is a function for adjusting the volume of the sound just before the vibration of the string stops when the keyboard is released. These three functions are parameters that require dedicated waveform data, and are not included in “waveform A”, but are enabled by waveform data included only in “waveform B”.

  If it is determined in step S31 that the event that has occurred is not an event related to the menu switch, the process proceeds to step S35 to perform other processing. Then, it progresses to step S36 and performs another process. If it is determined in step S30 that there is no event, or if the display process in steps S33 and S34 is completed, the process proceeds to step S36 to perform other processes.

  A menu event occurrence detection process for detecting whether or not an event relating to the menu switch has occurred is performed by the processes in steps S29 to S31 described above. In the parameter display process, when the menu event occurrence detection process detects an event related to the menu switch, the parameter corresponding to the type of the waveform memory identified by the waveform memory identification process performed in step S22 is displayed. Displayed on the display devices 108 and 208.

  Next, in step S37, it is determined whether or not to end all processing. As a result of this determination, if the process is not terminated, the process returns to step S26 to repeat the above-described process. If all the processes are ended as a result of the determination in step S37, an “end process” is performed.
