I’ve se in the past another device with this function, basically trough usb you can share a guitar tone with de device and the it generates s preset that emulates that tone, maybe could be something like, you know the whole gig of some special tone (amp, cab, effects, etc) but you don’t know hoy to set up each, may you can use this function on the QC, to fix the tone and replicate the tone. This function already exist on the axe fx II and III.
Could you share a video showing how it’s done?
