Thanks again Jim. I saw that the harmony was written to the Melody track, but no midi appears on any other channel other than channel 1. I don't think it is going to be helpful if I can't see the midi.
Basically I wanted to experiment with some counterpoint in my harmony by manipulating harmony lines on the other channel.
I think I will be able to do this in RealBand (or failing that, in Ableton) but I think RB will let me do waht I want.
