I watched several of Marco's videos..
It appears to me that he often uses the D-deck (sequencer?) to control the patch changes (instruments), and expression changes.. It also triggers lead ins (percussion sounds mostly). I noticed voicings are also sequenced..

He seems to use a chart of changes that give him direction, but mostly the keyboard screen directs him along with the lead ins that are sequenced.

None of this will work unless you are player capable to perform like Marco.
