Hello, We're a six man podcast and to date, we've been using XLR condenser mics, a mixing desk with USB interface built into it and Audacity on a PC laptop. God knows how we've made it this far but someone, we have! Anyway, we've now upgraded our laptop to a MacBook and want to use GarageBand to record. One one of the issues we've had previously is that you cannot record the microphones on independent tracks with Audacity so if someone coughs, for example, you can't edit just the cough, you have to edit the whole thing which makes it difficult. Parking that for one second, the issue we're having with GarageBand is trying to set up multiple tracks for each microphone. I've seen this is quite an easy thing to do with aggregators etc however as I previously mentioned.....because we are using XLR condenser microphones, we are using a mixing desk with a USB interface built in. When hooking everything up to GB, the input option for each track option only shows two mics from the USB mixer, as does the aggregate configurator. Any ideas on how to fix this? Thanks
