So yeah, finally got the 500X. Really stoked about it, but I've got a lot ahead of me on my journey to POD HD enlightenment. Though the question I have isn't exclusively related to it. Basically, what I'd like to do live is play with a pre-recorded bass track. Drummer would be listening to a click track, and the bass track would be coming from a laptop into the 500X, and through the XLR out. But how could I separate the bass from the sound of the metronome? The first thought I had was getting some sort of stereo splitter, and panning the bass & click track hard left and right. Bass track would go into the CD/MP3 input, and metronome would go into drummer's headphones obviously. And then I wondered, would it be possible to rout the two tracks to output separately in my DAW? One going 1/8 in. aux out and the other going USB out? That's not something I've done before. The only DAWs I use are Acid Pro and FL Studio, by the way. Thanks.
