While this demo doesn't really cover LFO (Low Frequency Oscillator) action, the point was to share that certain modules have full VCO capability in addition to LFO. While I was fully aware about this from the VCO standpoint, I just realized a module I bought as a dedicated LFO also has full VCO capability. Perhaps my noob discovery will help others. Featured is the Corsynth VC LFO.
