I use my TI polar with standard MIDI I/O (not USB) and analogs outs using the SEQ mode (prefer SEQ over MULTI).
1) I use only 2 parts, set part 1 to OUT1 L+R and the second to OUT2 L+R.
Now for no reason, after turning on the TI, the second part outputs to OUT1 L+R, though the display shows OUT2 L+R.
2) The second problem is probably related, as the second part will play an init patch, though it shows the last patch that was selected for that part.
Doing a quick prog change +1/-1 brings things back to normal for the patch, though not for the outputs.
This doesn't happen everytime, but very often, pretty annoying 
And while I'm here, is there a way to have MIDI on LOCAL OFF by default when I turn on the machine using the standard midi ports ?
