and my face is red
because I knew about "smooth" controls
that let you send 14-bit values
by sending to two 7-bit controllers
that are 32 positions apart.

and of course 32-0 = 32...

so controller 32 must be the least significant bytes of controller 0!

very handy.

Twelve?  Surely, uh, eight?  Four banks (2 programmed, 1 custom, 1 
internal)
times two modes (Wind/XG -- the XG is interesting but not for a wind 
player...)

Wow, that's so arcane!

No -- but the Peavey PC1600 series has provisions for all sorts of
wacky ways to split up parameters so they must have encountered
a lot of special cases.
