Thread: Mutable Music Weasel.
Nicely done! And in fact, keep that Tides + Quad VCA together...that gives you the ability to mix between and vary the outputs from the Tides for even more modulation fun.
I wouldn't swap the MIDI out. That Befaco appears to be the right choice for the space vs. functionality. Nor the FX Aid XL...it's a great little module, does what you expect, and sounds really nice. The only thing that might give you some grief is the depth on that Doepfer A-171-2...it's 60mm, which is a bit much for smaller cases. But if it fits, again, keep it. This actually came out pretty well, given the size.
