VCV Rack by Eurorack

Free VCV Rack Synth Free VCV Rack Synth

This. Synth. Is. Insane. It's really an entire ecosystem. Although technically not a plugin (it' works as a self contained program on your desktop), we simply had to include it due to the very high level of awesomeness. It's designed to simulate the hardware Eurorack modules and in our opinion, it does a darn good job!

An absolute beast of a free synth plugin! This is an emulation of the KORGPS-3300 Polyphonic Synthesizer and it really does a good job of modelling the personality and uniqueness of the original. Our favourite bit - the resonators ❤️
