Many thanks to everyone for the comments.

Alyn - It was listening to Steve Winwood's Arc Of A Diver album that got me into synths in a big way. If you've not heard it, you should check it out.

Floyd - You're right, that trumpet is midi with a sound from Edirol Orchestral. Playing in the notes was the easy bit - the hard part is juggling the volume slider at the same time as the pitch bend and modulation wheels. It's listening to Steve Winwood that got me doing it - he's the master at it.
