Hello..i have the similar problem.
Basically the voice choice catches don't all work - just piano and clarinet work each time I press those catches. The entirety of different fastens either don't work by any stretch of the imagination, or just irregularly and arbitrary. Now and then on the off chance that I press the violin for instance, I can get the electric piano or trumpet to work. In any case, those outcomes are not steady.
Simply contemplating whether this is a typical issue or one that somebody has involvement in and can guide me on what to take a gander at for a fix. I'm getting it would be the part that controls the entirety of the voices?
