Using Fast Track Solo with iPad and iMac

[ajw31]

Just recently purchased an Avid Fast Track Solo.

One of its selling points is connectivity with an iPad and it comes with a connector cable, which is great.

I've successfully plugged a guitar into the Fast Track Solo interface and recorded music into Meteor, an iPad recording app. This establishes that audio can be recorded from the FTS into the iPad.

What I can't do is get audio from the iPad to play back to an iMac, which the FTS is connected to via USB.

I can't work out from the documentation whether I should be able to do this or not. (Though I would have thought this was an obvious one.) I figured the sound quality would be significantly better than taking the headphone output directly into the iMac.

Has anyone else been trying this, or can give me a clear answer whether the FTS should be able to do this?

Interestingly, the FTS comes up as an input option in the iMac's 'Sound' settings panel.

Thanks,
