Physical modelling synthesizer



Physical modelling synthesizer brings digital pianos evolution to a close and allows the musician to perform on it exactly like on a live one.

Instruments based on physical modelling eventually will take over the market of digital pianos.


We have developed an algorithm, which models all significant processes, taking place in an acoustic piano during performance. The algorithm is implemented on an FPGA and has been highly appreciated by professionals.

The device has been called Pianoid. Pianoid's sound is indistinguishable from that of an acoustic one.


Pianoid based instrument allows the performer to control instrument's sound in the same way as on a grand piano. This control is the most important aspect and the essence of performer’s ingenuity.


Pianoid's sound is based on a preset - a set of coefficients, which characterizes an instrument, measured on particular grand pianos. Thus, Pianoid instrument can sound like Steinway&Sons, Bösendorfer, Fazioli or a honky-tonk piano. Like historical grand pianos of Rachmaninov, Tchaikovsky or Mozart.


In the end of our work, Pianoid will be a specialized microchip on a miniature motherboard.


Mass technology utilized in digital pianos today is sampling. Usage of sampling is inconceivable in classical music performance and destructive for musical education.


The developed algorithm has been implemented on a prototype, built on a XILINX VIRTEX xc7vx690 FPGA. Its capacity was sufficient for 33 keys (with 2 and 3 strings under each) and a full grand piano soundboard (up to 18th mode)



The cut version Pianoid prototype is available for listening. However, a real appreciation of the instrument's features could be acquired only "under fingers".
