Reading voltage from analog inputs? (mapping and quantising voltages to midi notes)


#1

Hello everyone! I'm trying to do some math with voltages and resistors, is this possible with the axoloti?

What I want to do is map a range of voltages to midi. I guess it would be fine with the range of 64 the axoloti outputs as far as I can see, but for 12 options it's quite small ranges. What's the best way to do this?

You do easily patch this. First connect your voltage to the Analog input (do not connect more then 3.3v or you will fry the analog input on the axo) then see what range comes through with the standard range of 64, so if say it is 12, then you can augment the values with maths etc to get the right mapping and triggers if you want to initiate midi events.
