Thread: My unhealed Eurorack
I would look into buying a complete synth voice: Intellijel, Pittsburgh, and many other manufacturers offer them. Most of them are completely patchable between each individual component. They'll include one or two VCOs, a filter, a VCA... and maybe some other goodies. Once you have that, you might want to think about sequencing. How do you intend to trigger notes and modulation?
