That is fantastically helpful - thanks. I was looking to sequence the Minitaur using the Arturia, so: GR-55 into Minitaur into Arturia.
I was also hoping that latency issues would be minimal as the tracking of the GR-55 (which I only use with MIDI, not bass/MIDI blend is very, very good). I suppose the proof will be in the pudding. I'm not sure if the GR-55 MIDI out is also a MIDI thru, but a MIDI merge box is an easy fail-safe.
