I would like to visit "retrig city."
MIDI retrig should definitely be in the cards; it's technically quite feasible at a rather high rate, at least.
MIDI bandwidth is 3,125 kbp/s, so that's like 1,000 messages per second.
The problem is that we don't know how complex Digikat MIDI message strings can get (with all the LFOs, parameter-locks, etc.), so that may cause delays or stuttering. Combine that with the fact that the receiving device might not be "modern" enough, and then you see how the retrig function might be limited.
If there are MIDI tricks, you can bet Elektron knows 'em!
