Hello,
When I tested once the Axe FX 3, one very convenient stuff (for those who don't use a DAW and don't have an audio interface,) was that the USB port was usable both to play sound from the PC and to record sound from the Axe . It seems it's not the case with the kemper.
IMHO, it shouldn't be so hard to do, USB2.0 is fast enough and on top of that the sound is already digitally converted without latency by the unit...). Is that for some reason impossible to implement in the kemper ?
