I designed an external midi in and out that fits on the back or side, should be here in a few weeks.
In the meantime been playing around with the Volca modular and as @jeye_musik said it is a great little synth, it works really nice with other gear, in isolation without patching it is dare I say it a little boring and vanilla, I suspect that a lot of new users might return or resell if they don’t explore it deeper. But once you delve into the patching it really comes to life, I had a nice heavy kick and FM acid type bassline going, and once I started tweaking it morphed into a percussive metallic sound almost like a steel drum, etc etc. Also looking forward to cross patching with my bastl gear via my modularhead board.
It definitely seems more suited to allowing it to be its own thing rather than approaching with a fixed goal in mind, it can easily be predictable and well behaved but it is better (for me) when just experimenting and see where it takes me.
I think Techno and Electro heads will love it if they give it a chance, even if those genres are not necessarily what you expect a buchla inspired synth to be well suited to, at times it sounds like Drexciya meets BBC Radiophonic workshop
