The sequencersetup is just difficult to figure out. What synth was used for the Oxygene seq for instance.
If we are talking the Oxygene DVD, The Memorymoog and the RMI were hooked up to the Digisequencer. Since the MM was used for the leads during Oxygene 2, it could not have been used for the sequence. I have no idea what Claude's Minimoog, Synthi A and 2600 were used for.
What the Loop Stations were used for, is also completely unknown to me.
For this tour the Digisequencer was replaced by the computer sequencer. Now it's just a question how it was controlled. In some of the early rehearsal photos, Claude has the computer monitor in his setup. It would be logical if he was taking care of all the sequencing.
Regarding the Digisequencer, Im not sure whether it has a song option or not. Otherwise it would be difficult to trigger the Minipops without doing it manually.
Woah maybe Im just thinking too much, and maybe some questions are better left unanswered
