Useful details from the exchange:
- the CC out feature from 3.0 firmware does not work at all in MPE mode
- notes can be sent out from the sequencer not parameters
The first point is a real shame for me as this feature alone would have basically justified the purchase as a controller alone. I've mainly been using it with an Axoloti and an MPE grid + CC out on 5/5 Env/Lfo with waveforms etc is extremely useful when designing patches. I basically have to choose now between the very useful CC out or the very useful MPE, but not both. Stopping just short of next level utility and greatness

Maybe they'll release the firmware as open source or something at some point. I imagine if this had been a hit they could have dedicated a lot more time to optimization and development. I wonder what the story is? mainly why Dreadbox did such a poor job on the filter (the actual first thing a potential buyer checks that seems to indicate quality in a synth) given their reputation i can't really believe they were satisfied with what they produced. Seems very, very odd. An unfortunate choice as its likely informed a bit of an industry precedent against more innovative and future oriented approaches to design.
Looks like we might be stuck with bolted on mono-aftertouch, 12-ET, piano keys a while yet...
