Have any of you geniuses/lunatics built a VCO from an Arduino?
I’m currently working on an 8-bit wavetable VCO on an arduino and i’m curious how I should handle the CV input into the arduino. After some googling around i’ve seen some similar forum posts with quite a lot of variety in methods on how to deal with CV input and I’m unsure of the direction to take.
It seems a lot of problem focus around the fact that CV could be -5v to +10v, but at the same time I’m thinking, since I’m building my Kosmo system from my own modules, i could make sure that I keep CV within the 0v-5v range and not bother with this? For example, i’m planning on using the Korg SQ1 as a sequencer which I believe only does 0v-5v.
The other part I’m not sure about is how to properly scale the 0-5v input to the correct frequencies for the oscillator to produce the correct notes.
