In step 740, one or more parameter generation sound that Signal Matching unit 430 can be generated based on step 730
Sound control signal (in the present invention also referred to as " control signal ").Sound control signal can include one or more of electro-acoustic
Individual feature, the feature include frequency, frequency spectrum, duration, amplitude, volume, tone etc..In certain embodiments, with pressure
Related parameter can be converted into sound control signal by certain algorithm, the conversion include but is not limited to Fourier transform,
Laplace transform, wavelet transformation, modulation (for example, pulse code modulation or PCM), waveform processing etc., or its any combination.
In some embodiments, sound control signal can include by the use of the device such as audio player, loudspeaker, earphone or microphone with
Produce sound.For example, according to audio format, external device (ED) 120 (for example, audio player) can be based on one or more algorithms
Sound control signal is converted into audio content.As another example, external device (ED) 120 (for example, loudspeaker, earphone etc.) can be with
Audio content is converted into sound.In certain embodiments, sound control signal can be encoded, encrypts or compress.At some
In embodiment, sound control signal can be stored in memory 440 after it is generated.In certain embodiments, piano system
Sound control signal can be output to external device (ED) (e.g., external device (ED) 120) by system 100, and external device (ED) 120 can be by sound control
Signal processed is converted into electro-acoustic.
In step 750, signal grouped element 420 can the group result based on sensor signal screen 620 is divided
Into different parts.For example, as shown in figure 6-b, after sensor signal is divided into group A and group B, signal grouped element 420
Screen 620 can be divided into part 621 and part 622, which part 621 can show the music score related to organizing 631 and void
Intend the related visual information of keyboard, part 622 can show the visualization of the music score related to organizing 632 and dummy keyboard correlation
Information.
Fig. 8 is the mistake for being used to realize piano system transposition technology that some implementations of foundation technical solution of the present invention exemplify
The exemplary flow schematic diagram of journey 800.
In step 810, keyboard can be divided at least two parts by signal grouped element 420.For example, as shown in figure 6-b,
Keyboard 610 is divided into group 631 and group 632 by user by input/output interface 410, and signal grouped element 420 can will come from group
631 sensor signal is appointed as a group A, and the sensor signal from group 632 is appointed as into a group B, while these are specified
Sensor signal is sent to Signal Matching unit 430.
In step 820, pitch matches device 431 can be 632 points of group 631 and group based on the information obtained in step 810
With octave.In certain embodiments, an octave range can be distributed to one group of sensor signal, institute by pitch matches device 431
Sensor signal is stated to be grouped by signal grouped element 420.As shown in figure 6-b, keyboard 610 can be divided into by signal grouped element
Group 631 and group 632, pitch matches device 431 can match the sensor signal for coming from group 631 with C3-C5 octave range.
In certain embodiments, can be produced corresponding to the control signal of sensor signal by Signal Matching unit 430.In some implementations
In example, sound corresponding with control signal has Senthesizer module 230 to produce.
In step 830, tone color adaptation 432 can be each part point based on step 810 and 820 information obtained
With tone color.Tone color adaptation 432 can match specific tone color to the sensor signal generated by sensor 340.For example, such as
Shown in Fig. 6-A, tone color adaptation 432 can match the sensor signal from white key 633 with piano sound, and based on letter
The control signal of control signal and white key 633 produces sound number caused by matching unit 430.In certain embodiments, there is steel
The sound of qin tone color can be produced by Senthesizer module 230.As another example, tone color adaptation 432 will can come from
The sensor signal of white key 633 matches with guitar tone color, and the guitar tone color is based on controlling caused by Signal Matching unit 430
Sensor signal corresponding to signal and white key 633 is produced by Senthesizer module 230.In certain embodiments, tone color matching unit
432 can be that one group of sensor signal matches tone color.In certain embodiments, sensor signal group can be by signal grouped element
420 packets.As shown in figure 6-b, keyboard 610 can be divided into group 631 and group 632 by signal grouped element 420.Tone color matching unit
432 can match the sensor signal for organizing 631 with guitar tone color, therefore can be based on the sensor signal corresponding to group 631
Caused control signal produces the sound with guitar tone color.In certain embodiments, tone color matching unit 432 can be difference
Sensor signal group distribute different tone color.For example, tone color matching unit 432 can by organize 632 sensor signal with it is small
The tone color matching of violin, and the sensor signal of group 631 and the tone color of piano match, so can in two or more players
To be played on a piano simultaneously.
In step 840, screen can show the visual information related to the state of every group of keyboard respectively.Screen can be with
Show the music score selected by user 110.In certain embodiments, screen can also show the key for representing piano 130 and/or step on
The visual information of the state of plate.In certain embodiments, screen can also show virtual piano keyboard (abbreviation dummy keyboard), its
Middle dummy keyboard can show the state of the key of piano 130.When user 110 presses one or more keys of piano 130,
Each key of dummy keyboard on screen can change its color to indicate that the corresponding key of piano 130 is pressed.When user 110 releases
When putting the key pressed of piano 130, each key of the dummy keyboard on screen can change its color to indicate that piano 130 is right
Key is answered to be released.In certain embodiments, piano system 100 receives the state correlated inputs corresponding to keyboard subregion, generation
The visual information related to the keyboard subregion state corresponding to the correlated inputs.
Being preferable to carry out for the present invention is the foregoing is only, is not intended to limit the invention, for the technology of this area
For personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
