Here’s a first video draft of the VCO for the ModulArduino project.
The code is based 50% on MozMo, 50% on the standard Mozzi library, with a small help from Mozzi usergroup.
On the video I have a prototype of the VCO controlled by a BeatStep which also drives VCV Rack.
The upper scope shows waveforms from the ModulArduino VCO.
The module so far has controls for Coarse and Fine tune, Waveform select button (Sine, Saw, Square and Triangle) and a CV input for CV (I still need to make it standard V/Octave)
