Hello Everyone,

Just wondering if anyone has had this little bug or something with their Mark4. 
I have a playlist with a mix of about 60 songs, they all play fine but about mid 
way I suppose, a song will play and it will start with the proper piano, it 
might play a few notes then it stops and plays it on the Synth piano or it just 
starts with the Synth. It can do it on a stable songs for example "Sue 
Downs/Yamaha song" that never gives me trouble normally, but it might even be 
any other midi song. The next song might be fine but the one after then plays 
back on the Synth.

On the PDA I can easily click next a few times, the Channels 1 and 2 are # or 
they might even be forced from me before to 01, if I just toggle it from # to 01 
it then starts to play on the piano, but next time it might not.. or it can be 
on 01 already and I have to toggle to # then back to 01.

So my only 'theory' is some weird residual midi data is hanging around from 
another song. So I need some sort of soft reset midi file, similar to the Panic 
Button on Cakewalk (rather than a whole shut down of the piano).

Any one else have this problem or have any ideas?

Thanks for your time,

Philip
