Missing notes
 

On some patches in the Ti (using OS 1.09) I get missing notes so I can be playing a chord or note or whatever and no sound will come out from approx 9 out of 10 key strikes. I change to a different patch and it's ok. It seems to affect some patches all the time but most patches are never affected.

It occurs when playing back MIDI notes in Cubase as well as striking keys in realtime.

Any thoughts?
