Hey Ronin,
Thanks for the reply. I plan on keeping the Minibrute 2s and 0-Coast as a core part of this setup. My original reason for getting the Rackbrute was to further sophisticate my desktop modulation and I quickly found myself planning out the rest of the rack. The appeal of the Rackbrute in specific was how easily it marries with the Minibrute 2s.
I was also flirting with the 4MS Spectral Multiband Resonator over some of the effects modules. Any thoughts on that?
