The midi send panel in Cubase 12 is fairly full-featured with its arpeggiators, etc. What would be interesting, I think, is if there was some kind of polyphonic midi note distributor. That is, I set up three or four, or more, mono synths and route them all to one module where each synth would play the different notes of that chord in real time. You can do this in Bidule by having the synths be on separate midi channels. It’d be nice if this function existed natively without needing a plugin.
