This VCO is almost as basic as it gets - sine, triangle, sawtooth and square wave outputs and CV inputs for pitch and sync.
However, what makes it even better is that you can switch the octave range AND you can turn it into an LFO! Which can still be controlled with CV, which means you still get 4 LFO outputs of different waveshapes.
Considering how tiny it is, it is a great modules with lots of features.
Also, even if the VCO waveforms are basic, it still sounds great!
