Digital Piano

Well the physical build would boil down to buttons actuated by levers and springs. It would get expensive, time consuming and tedious quickly. What do you mean custom keys? Just a custom layout?

No like it uses a tunning that is different from equal temperament, and I meant electric keyboard. Like a synth ect.
Since its a prototype it doesn't really need to look like a keyboard it can just be buttons. I need it to write the theory.

How many buttons/keys?

>>1116335
wait I need to check my book to be sure.

>>1116335
counting A=440 and its octave 880,
18 keys.

Could be done with an arduino using a parallel to serial shift register for input (so you can have multiple buttons pressed at the some time) and the a decent DAC for audio out.

I'd probably try to repourpose a keyboard than make one from scratch. Even if it is just a computer keyboard.

I would but I do not know electronics. I'm learning how to build acoustic pianos but making it acoustic would cost a fuck ton.

How do you think a digital piano is made?

why do you think I'm asking for help?
