Oops, maybe the SPST switch on that pot isn't enough to implement the cv invert feature? Somebody smarter than me needs to address that.

Would it fit beside the CV Invert switch to make a 2U layout? I see from the schematic that it's only single pole, and SP4T slide switches are readily available. For instance Digi-Key has this one for $2:If it wouldn't fit, could we replace the CV Invert switch by a switch on the Frequency CV pot, to make more room for the Mode slide switch? Maybe a switched pot is a little easier to find than concentric ones? For instance Digi-Key has this 100K linear carbon switched pot for $3.50:I'd really like a 2U layout.skwOn Aug 22, 2009, at 4:48 PM, Scott Deyo wrote:
Yeah, I always balk at moving jack above pots, though that's a little silly. If you have more than one row of modules, you're going to get cords over your pots anyway, right?What do others feel about this?I really wanted to do 2U, but I don't think folks (and I count myself as one of these folks) have access to concentric pots.Scott DeyoThe BridechamberJealous Edison Record KompanyOn Aug 22, 2009, at 3:55 PM, John L Rice wrote:Wow, tough call! If I were doing it for myself, I would do one of two things. If I went with the horizontal version I’d go off the standard MOTM grid and move filter A’s jacks up into the section with the controls and move section B down a bit etc. But if I really was going to build this I would do the vertical design but in 2U instead of 3U by combining the Frequency and Frequency CV controls into a dual concentric pot (if possible), moving the Mode switches down to where the Frequency CV controls were and then move the Input jacks up and the Output jacks over underneath the Input jacks.

Well, you can almost always fit a toggle somewhere, and the CV Invert is just there because there's plenty of room. We could even get rid of them and add an Inverted CV Input with attenuator, kind of like Richard said.
The reason I was going towards switches and "non-standard" MOTM spacing (does this really mean anything anymore, with MOTM using different knobs and LED displays and such?) was to set it visually apart from other modules in the system.
I just don't see any way the 2U will work, and I'd like to skip the small-pot spacing on this one.
You're still getting two full state-variable filters in 3U....
