Thanks Mikke.

Yes they are displaying correctly on the sheet. And I'm using real tracks, it just seems odd that it won't play the extensions sometimes in the jazzier styles. I'll keep playing around and if I have no luck I'll email over the track.

I have a lot to get through though so I really just need to know how to control it for myself, I'm writing backing tracks for teaching guitar improv and I'm on backing track No. 412... it's a rather large project I'm working on.
