>>Did the P3 stop<<  

yes, exactly as if I'd pushed "stop", which I didn't, but I was tweaking summat at the time... probably in mixer mode.

>>could it have received a stop message at its input ?<<

no- all there is upstream is an evolution keyboard, one of the basic ones with no transport facilities or clock o/p. the p3 is master clock these days. 

I'm wondering if the switch itself could've been set off by contaminant ingress of some sort. we weren't smoking, & it wasn't very humid. this happened three times in one piece (i.e. in the space of ten minutes) on saturday, then on sunday it was fine all day.

is there any way, under any circumstance, that the p3 could be programmed to stop on it's own? I don't think I've seen this....

downstream, however, is another story.... MOTU micro-express, maq, another keyboard... 
the maq has to receive clock from the p3 & remote control from the other keyboard, then it re-enters the MOTU as a source to be merged with both keyboards & the p3 & off to the various noise boxes. but I decided some time ago to run the p3 with FTS off at all times, & use custom patches in the emu modules for anti-bum-noting the maq.

the MOTU was fiddly to set up, but the pay-off is better merging & timing stability- previously I had three merge boxes cascaded & lots of clock problems.
