This could potentially be a dumb question, so be easy haha. I need to record a video into my iMac computer, I am using iMovie, as well as the built in camera. The iMac is a late 2012/early2013 model with no audio input, just usb. I need to make this video with a backing track as well as guitar on top. I've tried running the track into the cd/mp3 input on the HD500. It outputs sound at the 1/4" and XLR's, but not through the usb. The guitar part I'm playing does go through. Is there a setting that will correct this? If not, any suggestions on an easy (ie; affordable)way to do this?
I've also tried running the backing track on the computer but it appears that I can pick either the computer's audio, OR the Pod's, not both.
And while I'm asking those who would know - can 2 separate usb sources be run into the mac to record at the same time, or would that require a usb interface with dual inputs?
