I have had the OT 6 months and now I am going through this issue as well.
Okay, here's what I'm thinking. Percussion has been drawing more and more of my focus. The obvious choice and the one most people I have read choose is OT as master.
My setup consists of MD, OT, x0x, Little Phatty, and a Simmons sds-400 tom brain.
My main issue comes down to swing! But pattern changing, mutes, ect. are also a consideration.
If I use the OT as master the MD is limited to 4 swing percentages
0, 55, ?, and 80).
I can compensate on the OT with micro timing. I think I will be okay with slight warbling
I love sequencing the x0x with 2 to 4 MD tracks. Swing is a big part of that.
I want to give a solid go at sequencing MD mutes on the OT and OT mutes on the MD.
The routing I am considering:
MD master clock. Midi machines triggering the x0x and OT pattern changes/mutes (pattern changes on the OT not synced to MD pattern changes, I will be using bank/program change on the previous pattern and amp level mutes), 2 individual outs triggering two voices of the Simmons brain with the audio routed back into the MD.
OT slaved to MD clock and transport but not changing patterns automatically with the MD. OT midi tracks controlling the LP and MD (when retrig, micro timing, and different track length/time sig is needed and for mutes).
Any things to consider or a better way to do things?
