Wow, very impressive revision. Lots of useful features, and the additional processing power is very welcome for building complex patches in ORAC without hitting the ceiling. Speaking just for myself, the addition of MIDI DIN (edit: oops, 1/8" TRS MIDI - the video confused me about this) makes it a very cool companion for the Empress ZOIA (which lacks USB MIDI).
Only questionable addition for me is that big honkin’ speaker on the left, which adds considerably to the length. Granted, it’s probably a very good speaker, unlike the OP-1’s. Maybe even better than Critter & Guitari’s eurorack speaker. But I just keep looking at the thing like “Why is it so long? Does the M in ‘Organelle M’ stand for Mobile? How?” It simply looks unnatural in this form factor. But maybe I’m just used to staring at the Mk I Organelle for hours on end.
