This VCV Rack Ideas video explores using the Macro Oscillator 2 in VCV Rack, the free open-source software modular synthesizer.
Macro Oscillator 2 is a software version of the Mutable Instruments Plaits module, a multi-function oscillator for Eurorack systems.
This video takes a look at using Plaits in VCV Rack, but most of the patch examples should apply equally well to the original hardware version.
