Thanks Everyone.
Medium-sized: If I add up all the modules I have completed building which are waiting for cases, plus all the ones waiting for me to finish (electronics is a hobby), I have probably around 60U or more of space, including a couple sequencers. In my smaller portable case, I have four oscillators, a couple filters, a bunch of support modules (22U total), and then sitting outside it but powered, a dotcom sequencer, quantizer and a couple other modules. I have several other types of oscillators and filters completed, plus some interesting projects (full synth voices from kits, a tau phaser, jupiter and arp clone filters, several Music from Outer Space modules and voices, etc.). So medium, if you consider something like John Rice's rig to be "large"
I generally tend to sequence the modular, but I think that has as much to do with not having a good controller as anything.
I'd love a voyager, but I do see what you guys are saying about the controllers. This is great feedback for me to weigh in. Thanks.
I suspect I'll need to take a hard look at my space and get a good controller while saving up for the voyager and maybe removing something else to make space. I know there's overlap with the Slim Phatty there, but for reasons I put out elsewhere, I don't noodle with the slim phatty as much as I prefer knobby synths. I'd like to get to a point where between the modular and a couple keyboard-laden Moogs, I could do more "live" work and less overdubbing. It simply makes it more fun and helps me improve when I can work that way.
@EricK: Your rig is beautiful! You need long arms to play that Theremin, though

When I saw your photo, this was the first thing to pop into my head:
PS: Yes, I'm on Muff's (mostly the 5u forum) and in GearSlutz.
