200e

OK, so based on comments from Johan <JB> and Chris <wiardmodular>, as 
well as some private email, I probably just have something wrong with 
my 225e. That's actually good news, IMO.

Just for the record, my 225e setup is something like:

Note buss A, B & C (on MIDI Chan 1, 2 & 3), mirrored to Busses E, F & 
G. Buss H is on MIDI channel 8.

I'm using maybe ten CC busses, with speedlim-ited controller streams 
(from Max/MSP).

The 225e seems to be particularly vulnerable to hanging right after a 
preset is saved or restored or when freshly powered up.

Sending notes on MIDI channels other than Chan 1 (or perhaps busses 
other than A) right after saving/restoring/powering up increases the 
likelihood of a hang dramatically.
