This July 2010 photo shows the whole studio setup with all modules ready to go and something patched.  The portable cabinets are to the left, doing duty as overflow cabinets.   There’s still some space left for expansion.

To the lower right sit the Mackie 802-VLZ3 mixer, the t.c. electronics Desktop Konnekt6 Firewire interface, and a rack holding a Furman power conditioner, a pair of FMR Audio Really Nice Compressors, a Lexicon MPX-1 Multiple Effects Processor, and a Tascam SS-R1 solid state recorder. The monitors are Mackie HR-824s. I store the M-Audio Axiom-25 on top, because I don’t use keyboards a lot.

Cabinets and Power Supplies

Three of the four cabinets are Synthesizers.com four-foot long 22-Space Walnut Studio Cabinet, modified with Stooge mounting rails to hold MOTM-style modules.The bottom cabinet is a 44-Space Tilted Walnut Studio Cabinet. Each tier holds 26U of modules. There is 130U of module width total.  The portable cabinets add another 40U.

Power in the main cabinets is supplied by six Power-One supplies:

  • 2 of HAA15-0.8-A – from MOTM-900

  • 2 of HTAA-16W-A – from MOTM-950

  • HBB15-1.5-A

  • HCC15-3-A

Electrical Standards

With few exceptions, signals are standardized.

  • Signal and control outputs are +/- 5V, including pulse waves.
  • Most gate and trigger inputs have Schmitt comparators that accept any signal.
  • Envelopes are 0 to +5V.
  • VCA unity gain is at +5V.


A module in the logical sense is a self-contained functional unit whose inputs and outputs are available for connecting it with other modules into a “patch”. Physical modules consist of a panel unit that is movable independently. Quite often you see multiple logical modules contained in one physical module. Here is a list organized by logical function.
