What do you do when the synth gets a little too big... especially for managing here on the grid? My system is in 7 cases, the Center, to which this post is attached, is pretty much that, the heart of my system featuring my mixer, basic send/return effects, monitoring, clock, modulation control devices, and some of the modulation sources.
The basic config is three 6u Doepfer 84hp bases with three 9u Doepfer 84hp cases set above them. In the case of Center, there is an additional 6u Doepfer case above it that I refer to as "Special Teams," containing my "trautonium" rig, Assimil8tor, drone/noise sources, and (for the moment), a Intellijel Rainmaker. Some cases include a Plumb Audio Rack Plumber, which passes 18 channels of signal via HDMI cable to several of my special purpose satellite racks.
In all, there is one large, very capable modular system (in 7 cases), with Center (described and included on the grid... I will get to the others eventually), right beneath the previously described Special Teams, as well as five others: a sequencer rack, a voices rack, a drum rack, a drum sequencer/drone rack, and a FX rack.
Among the satellites are: an electro-mechanical percussion rack, a Midi rack (tall and slender) beside my computer (with interfaces, monitoring, and input capabilities, and a Moog semi-modular system.
