Struck-string instruments such as pianos usually have groups of strings that terminate at some common bridges. Because of the strong coupling phenomenon, the produced tones can exhibit highly complex modulation patterns, and synthesizing such complex tones turns out to be quite complicated. It is also difficult to determine the synthesis model parameters such that the synthesized tones can match the recorded tones. This paper proposes a multichannel recurrent network based on three previous works: the coupled-string model, the commuted piano synthesis method, and the infinite impulse response (IIR) synthesis method. This work attempts to automatically extract the synthesis parameters by using a neural-network training algorithm without the knowledge of the instruments' physical properties. Encouraging results are shown in the computer simulations
