It's been a while since I ran these experiments, so YMMV.

One idea: when doing a 14 channel piece with much poly~ use, I found that scripting the patch cords I need (and not the ones I don't) saved me a lot of overhead.  That might not fit your situation.

Second idea: I found that manging signal routing with matrix~ was pretty efficient... probably more so than a number of small gate~'s.

A comment: make sure you "zero" any sends before you mute them.  If I recall, send~ holds the last signal vector it has gotten when it gets muted.

good luck,
