I just bought a Boss Katana guitar amp, with a USB out. The amp connects fine to the Mac, shows up in Boss Tone Studio, is available as an input or output in the Sound control panel, and the Audio preferences of Logic. I set the main interface as the output, the Katana as the input. The Katana produces a visible level in the mixing board, but when I hit Record, it just doesn't record. Even when I have evevrtything set up "correctly," the Katana does not show up as a potential input in the channel strip.
So it LOOKS like it should record, but it doesn't. Any clues? Anybody else using the USB out from an amp into Logic?
