Hi Noel. When I click "Options, preferences, MIDI Driver" I get the attached message. So I did that install and it fixed the sound on the missing tracks. However I still get a reasonably short regenerate. Would that be due to the fact that the drums are a real track? I suppose each new real track adds more regeneration time.

Anyway, thanks for the help.

John
