I would LOVE to see MIDI over USB on the Octopus/Nemo. In my opinion, the bandwidth limitations of standard DIN-based MIDI are the greatest flaw of these sequencers. The amount of data you can spit out soon overwhelms the connection and leaves you with timing problems. MIDI over USB would solve this, at least for those of triggering software as well as hardware.
Unfortunately, Gabriel has told me in the past that the current hardware is not capable of this, so I doubt we’ll see it. Although personally, I’d quite happily pay to have the hardware upgraded to make this possible…
