This is a great device and its helped me a lot. I have added additonal functionality to make it stop the held note when i apply aftertouch of a certain velocity, quite useful. There is one question I have, it seems that when you press down a key, and then press down another key whilst pressing the first it will sustain both notes, this is somewhat useful but it would be better if it could be controlled with a toggle switch. The single note functionality is supposed to do this, but it seems that when one note is depressed and then any additional notes triggered will also be sustained. Could you perhaps advise on how to change this?
