've got a mcbook pro and I want to video my musical jams ..me on guitar and a friend on bass ..using 2 audio tracks in GarageBand with apple loops for drums... with a usb audio interface for the AUDio and iMovie with the Mcbook pros built in camera for the video is this at all possible ? I also saw a app called SOUNDFLOWER which seems to be a audio re-routing app..... can this app help ? i guess I'm thinking about multitasking with both the GarageBand DAW and iMovie Video Capture running in parallel !!! Any chance ? or could u suggest another cost effective route ?
