tried that rharv but I don't get the track option. i get merge to stereo wav file, compressed file or wma.

no option to bounce all the midi tracks down to a single audio track on the same PT tracks window which would make it easier to balance backing and vocal.

I can't remember how I did it in the past. maybe I recorded the midi onto an audio track or exported a wav file and then loaded it back.

shame i haven't got the stereo track option - that's what I need
