Looking to make a microtonal music keyboard. I would like to find a STM32 lay out for a standard, midi, with velocity sensing keys (timing between two contacts per key) keyboard and with the C program that I can use as a guide to modify for my use.

Any Algorithm for scanning, timing velocity, and or to midi would help. I could do the matric lay out. I do not want to reinvent the Wheel if posable.

Thank you, ƒg.
