Dear all, I’m really a newbie (a great one, and french so please forgive me for my explanations). I have the project to create my own pipe organ console. The problem is that the project is quite huge and my knowledge quite small. New to electronics I wish I do this myself from the beginning to the end. So it consists in a 3x61 keyboards + 32 pedalboard + around 200 stop switches and other buttons. Maybe later a swell pedal and a preset for combinations but this will be discussed in time. I really don’t know how to realize this for the best. Which hardware? PIC or STM 32? What would be necessary to take in count all this with efficient throughput to enable aftertouch? Finally this console must be linked to a PC for replay system, partition editing, etc… Thanks for any help
