I have a Yamaha EX5 and DS11 drum rig and I'm trying to find how, if possible, to 'step through' the EX5's internal sequencer one event at a time using an external MIDI controller - in this case, one of the drum pads on my DS11. The goal is to create a pattern, record it into the EX5 sequencer and with each successive hit of the drum pad, trigger each note of the pattern. This will allow me to get perfect sync effects a la that passage in King Crimson's 21st Century Schizoid Man where the snare follows the guitar riffs relatively painlessly(!) In an earlier MIDI setup I had a while back, I think this was referred to as 'conductor mode' or some such thing.
