Am I missing something? I know I can route audio output from my computer to the Axe, and that it'll play through output 1 on the Axe. Whether that's playback during recording or just jamming along with a track, it's a nice feature. The only problem is that I don't usually have my monitor plugged into output 1. I use output 2 for my monitor, and output 1 is for when I want to run XLR out to FOH. In the situation where I'd want to use this USB input, I'd want it to go to the monitor. I keep my cable for the monitor audio and power connected in the rack and coil it up in the back. While it's certainly not a huge deal to unplug from output 2 and move to output 1 when I want to use this feature, it's a mild pain to have to do so.
I realize that out 2 is used by some as an FX loop, so the USB input being routed to that would cause it to feed back into the signal chain. But I don't use it that way -- I use the two outputs as equal, separate options for different purposes. I'd like the USB input -> output feature to be available on both outputs. Is there an option I'm missing to enable this, or does this need to be a feature request?
