There is an audio track on the mix but I've got that turned off and the track I am recording I have set to midi.

I'm only using a controller and no mikes and the track shows up as a midi one.

Have now turned the "always record audio" off but haven't tried it again since then. have just bought a new edirol PCRM50 controller which I'm hoping will plug and play. Can't believe the manual is 124 pages long!
