yeah just a gate at the start of a sequence should do the job..
as for sending the reset signal to multiple modules, a passive mult (or stackcables, or headphone splitters) should work perfectly, it's a bit of a waste using the buffered mult from links - better for pitch (and potentially if you are re-patching triggers on the fly)
I generally only reset at the start of a track, especially when layering multitrack recording - so manually stop/arm things - black sequencer, BSP, sinfonion and logic (pams is set up to reset by logic not sending a clock for a while and then receiving one)

Utility modules are the dull polish that makes the shiny modules actually shine!!!
