Well, it seems the Multipedal is the first of a series of complex controllers. Otherwise, they would have called this Multipedal Forum.
The CP-251 Control Processor may fall into this category as well.
I never looked at it that way, analoghaze. I always saw the 251 as a module. But yeah. It really is a controller. Fascinating. 
The CP is a Moogerfooger (that’s what it says) with controlling abilities 
Be nice to see Moog come out with a keyboard controller, minimoog style pitch mod wheels, ribbon controller, arpeggiator, midi-usb-cv, etc. I like the pedals but i’m finding it harder and harder to get exicted about some of moogs latest products, ie: the moog gutiar, the newest mooger controller pedal etc.
+1 on the ribbon controller. Make it 30cm long, please!
