Been having fun with modular for quite a while... my first go-round was back in the late 90s with a 15u Doepfer system. Then I took a long break from music (huge mistake, selling everything!) but finally got back into synths 5 years ago.
I'm really delighted with how this system has come together, and what wild things it can do (unimaginable, really, back when I had that Doepfer system). I rarely patch the whole thing at once, as it's a bit overwhelming... I have an Intellijel 4.5u 104hp case that I use most of the time, taking modules out of the larger system and playing around with smaller subsets (I didn't post the 1u modules here, but the usual Intellijel utility stuff, with some NLC spice).
At this point, I have 27 empty hp to play with. Not in any particular hurry to fill them, but I'm curious if the experts here see any particular important missing elements that I've somehow overlooked (one that comes to mind is a matrix mixer, probably the Lion from Instruo, given that there's a Lion shaped hole right next to all of the other Instruo modules). One thing is for certain, and that is that I have plenty of oscillators/voices... too many, really, though choices are always nice.
p.s. the website is being a little flaky... there should be a Happy Nerding 3xMIA to the left of the 3xVCA... not sure why it isn't showing up here.
