Nice.
If I may ask for your advice on a related subject.
I have an old electric piano, it doesn't register dynamics, the strength with which I hit each note. Which is a huge bummer.
I can't think of a simple way to hack dynamics onto the keyboard, I thought of adding an additional sensor and using the time delta between touching a key and hitting the bottom, but that's not really correct, as you can hit a pianissimo key fast in staccato.
Maybe a basic spring that decreases resistance as it becomes compressed, but it might make keys quite hard, and it's not very simple to implement.
Any ideas?
Thank you.
