That's great you have a repeat for it Robbo. AJ will most probably report it to Ketron and that will give them a big clue to what the bug is. Even though Tony had the freeze without the pedal it still may well be polyphony related.

Even if users don't get a response from Ketron I am sure they are keen to clear up the bad publicity these problems are getting. If you go to Google and search for "Ketron Audya problem" ... this forum comes up at the top of the list. I'm sure they would prefer to clear that up.
