Thanks Mike & Bob.
I'm sorry, I should have been more specific.
The song in question is a mixture of MIDI & Realtracks. I use my keyboard through the Ketron and then save in BIAB. I then go into Realband and open the file; this is where it is all MIDI sounding.

I know I'm missing a simple step or steps, but I can't remember what.
Any guidance appreciated.


Cheers,
Keith
