Hi Ian,
regrettably neither John Smies nor myself were able to help. I personally don't do a great deal in the way of tweaking/editing sounds or performances etc, in general I'm quite happy with what's onboard,. I waste all of my time messing around with styles ( as you may be aware ,haahaa) . Unfortunately even though I tried to help Donny, I wasn't really any help.
Fortunately Col appears to have come to the rescue.
but perhaps John Smies, our resident Korg expert (and programmer), or Fran, Donny's knowledgeable mentor, will be able to find a suitable workaround.
Ian
