I´m really deep in VCV Rack . I´ve even written a whole e-book trilogy about making generative music with VCV Rack. I think it´s the most versatile modular synth software out there (perhaps together with Cherry Audio´s Voltage Modular - which is not freeware though). Some modules are a bit poorly documented, but all in all it´s a marvelous way into modular synthesis. I recommend anyone who starts working with VCV Rack to limit oneself to only a few basic modules, doing a long time experimenting with these few modules, and only then step by step expanding the system. There is a big danger to drown oneself in the plethora of available modules without really learning what each of them is able to do. Cheers and peace! Rolf Ah, by the way, there´s free e-book about the matter, which may help quite a lot: https://www.dropbox.com/scl/fo/nkzlk2vmfop66w8krmyjt/h?rlkey=tg0zkmccil0twpx87z7qn7826&dl=0
