Hello. Okay. I work at a performing arts hall, and we want to get into the business of doing digital recording. We have a brand new G4 eMac, 40GB HDD with 512 ram, OS X 10.4.6. We have a product from M-Audio called Fast Track Pro that lets mics be pluged into the device with USB out the back and into the Mac. The problem is I don't know how to set up GarageBand so it will take the M-Audio as the source. I did a little looking on the M-Audio site and found a designated GarageBand section, but our product isn't really mentioned, but one similar called Fast Track USB. The link is http://www.m-audio.com/index.php?do=products.filter&ID=garageband Basically, I was wondering if someone could tell be how I set up GarageBand (ie: Track > New Track > Real Instrument...) to work with the device.
