Firstly - Thanks for all your input folks.

The file is Funeral for a friend - Elton John. If you know the track you'll know it starts with a gradual increase in volume of a windy night. I've listened to countless midi versions and found one that was significantly better than the rest. I have spent many hours playing around with it using the DXi sounds and effects on PT. I play over it using my Korg synth and another Casio Digital piano. I have added some audio wind to the beginning of the track and everyone who's heard me play it says it sounds cool.

I have always been a little critical of some of the synth sounds and thought I'd play it through my Roland which has the ability to layer stuff up - some of the strings and synth sounds are really fat compared to the DXi. I have done the same thing with another track and it worked brilliantly so thought it would be a simple exercise to do the same thing with the Elton John number. I might have a look at the Roland settings for the synth and see if I can wind the sustain down a bit. Is there a CC no for sustain or rather which one is it? There seem to be a number of possibilities?

I'll have another go tonight and see if I can get some sense out of it.
