Scott, it doesn't sound like a glitch, but by design..It would seem to me the majority of players would want the one touch setting turned off, alowing your own sound selections rather than the preset ots..It would make more sense to operate this way than having to turn off the OTS all the time...Perhaps if Yamaha allowed for the OTS settings to remain globally[user choice] it would make more sense..
When I tried to use my PSR2100, I rarely wanted to play the OTS, while performing..
BTW, I don't miss the Yammy at all..and not because of the OTS..
