Also a fan of squarepusher!
I can't find many info on the QY700 sequencing workflow, but I doubt it's what usually known as a tracker. I see some screenshots that look like a horizontal piano roll-based view. Trackers don't use piano rolls but instead a vertical textual grid-based representation (so time goes from top to bottom instead of left to right).
If it's like the older models in the series, it has a few different modes, one of which is the edit mode which is kind of like a tracker where you fine tune the notes and events that you first write in the step or the live sequencer
Hmmm yeah. It seems I've been looking at the QY700's pattern mode and was under the impression it was a tracker. It certainly resembles one and the results in Tom's music certainly sound like one. I know from experience that it would be absolute hell to program that stuff in a piano-roll, so it seems unlikely that he's relying solely on that. Hmmm...
