When I pull the power cord from my TI (to simulate a power loss) and plug back again- the patch names of what I was working on in multi or sequence mode are listed properly on the display, however what I hear is the init sound. Oddly enough, when I play the keyboard, let's say in a straight quarter pattern, about half the notes I play are the correct patch and the rest are the init sound. If I change the patch forward and back one step on the TI, that corrects it.
What could be going on? Do I need a new battery?
