Hi Gary, thanks for the reply.

Question; you suggested recording the audio as a .wav,! Please forgive me if I have misunderstood you,
but I actually want to be able to make up a midi file - of something like a harmonica for instance, then, generate the "true" harmonica sound via a module or software? Record/save it then finally put it all together with the Realband real instruments score I've worked out .sgu - then bump it all down to a single track. I'm at a complete loss in how, or even if! It's possible.

Is it a case of either real tracks or just midi?

Unless of course a realtrack/band composition .sgu can be rendered in it's entirety to a midi file? In which case the problem is solved!

Thanks, Nic
