Someone commented on the limitations of drum sequencing with a 16x8 Grid and I recalled this clip from several months back when I first began to play with polyphony and multiple seqs in Dreamsequence.
It's not a particularly good clip- just messing around without going anywhere- but about a minute in it there are hints of an idea involving using multiple seqs with different Step Lengths for the same drum voice. Trying to reverse-engineer what is going on, there's some automation of pattern rotation and perhaps some Probability at play.
I'd like to explore this more and play with the Seq Start/Reset params. In particular, I think it'd be interesting to try manually triggering drum fills by setting the "Start" param to "Off/trigger" and then using the "Trigger start" and "Trigger reset" params available the system SEQ 1-3 parameter groups.
