I may not stick to this configuration at all as my system grows, but for
what it's worth, here's how I envision laying out my modules...

The cabinet configuration I'm planning will be a series of smaller cabinets
sort've like the Moog IIIp (I was even going to cover the cases in Tolex,
but after several list members yelled at me for that ;) I'm rethinking a
nice wood). My plans are for two rows of 10 1u-width modules each with a 3u
'utility row' along the bottom. Sorta FracRack size I guess, but I'm not
using that.

I'm thinking of putting controllers along the top row (Egs, LFOs, etc.), and
on the second row-spanning cabinets-signal sources (VCOs, etc.) and
modifiers (filters, etc.).

The utility panels will be tinkery stuff like multiples, inverters, logic
gates, stuff like that.

I probably wont adhere absolutely to this plan, but that's how I'm thinking.
The signal moves left to right along the middle row with controllers
"overlooking" from the row above, and the utility panels at the bottom for
quick CV modifications. Actually, as I type this, maybe I should reverse the
first & second rows so that the controller modules are closer to the utility
panels. We'll see.

I've got plans to tinker together some nutsy-cuckoo modules of my own, and
they may get their own cabinet after I have enough of them. I'm going for
that "Forbidden Planet" sound so I need some off-the-wall modifiers and
controllers.

When the sequencer comes out, depending upon its dimensions, I will probably
give it its own cabinet, and if there's space, put MUXs and other similar
devices in.

I kinda wish we could see the sequencer before I get too deep into cabinet
building, because I have a feeling that it will be the single biggest module
of the entire MOTM line for a long time, and it would help to see what the
'maximums' look like. But I doubt it will exceed the '19"-rack' wide limit,
and Paul has suggested that PCB depth probably wont exceed more than 2"
beyond the 4.5" standard.

Speaking of cabinets, I just got some rack rails in from Tech America and am
disappointed. They're heavy duty, but have a huge radius in the bend that
will leave a 1" gap between my module rows if I use them. I wasn't allowing
for that in my cabinet blueprints. I hate buying hardware through catalogs
without holding it in my hand first.
