Since you have the space, maybe consider a Doepfer A-143-9 instead of the A-145-4...

I would agree with everyone that you shouldn't necessarily plan everything out. I have a Rackbrute 6U filled out and now a 3U. I think in time I will get another 6U to combine with my existing 6U...I like what I'm building with the 3U accompanying my Minibrute2 keyboard synth...lots of effects/modulation in my 3U that really compliment/extend the Minibrute2.

Great suggestion! Love the expanded functionality of the Doepfer 143-9…. Unfortunately all my Canadian retailers don’t have it in stock at the moment…

I do like having the Quad LFO module…. So useful for pulling out multiple modulation sources. Do you know if anyone makes a clock-syncable quad LFO? Does the Xaoc Batumi have this ability? I do suppose I could look myself… but where’s the fun in that?!
