Right now, the go-to mixer I'm pointing people at when they need as much CV control as possible in the most convenient space would be Toppobrillo's Stereomix2. Not only does this give you CV over level, pan and AUX sends, you also have mutes on your inputs and you get a "strip to cue" function that sends your audio to the headphone jack from a selected input strip...which is INVALUABLE for live work, tuning purposes, and a bunch of other things. You could even use it as a second (manual) AUX. Plus, this is their rev.2 version, which means it's already debugged and tweaked for optimal performance. It's sort of like the Mixology...on 'roids!
