Yeah...I think that for the space vs function issues it deals with, the Erogenous Tones stuff raises the bar on function density in 3U. A combo of the VC8 + RADAR/BLIP provides pretty much everything you'd want in signal control in 54 hp. That sounds like a lot of space, but considering what gets dealt with, it's a great tradeoff. This can deal with both audio and CV simultaneously, can be made to function in a number of more elaborate envelope sequenced methods and, if you take another 10 hp for the Levit8, mixing for 4 channels each of audio and CV, or individual attenuation for any and/or all of that. Add the extra perks like inverters, offset gens, etc...these seem to wind up in all of my builds and build sketches in recent times for very real reasons!
