I've just observed a phenomenon on my Gearbox standalone app: in instrument input mode, two tone buttons appeared, so I could toggle between these separate tones. In other words, I could play my guitar in two-tone mode in a real time. Fantastic! I even got used to it, but after I closed Gerabox app, this possibility never appeared again. My question is: was it an error, or Gerabox has switchable two-tone ability for guitar connected to Instrument input of TonePort UX2?
