I been using it for almost 3 years and this is the best thing i bought that regards music. I hope that someone who owns it can explain me how to record both aux and guitar input in the same time on pc. PX5D as i could figured have only aux to usb and only records aux. When you are playing it normal you can hear aux but it is nothing being recorded (sent through usb). I want to play song through aux and play along and recorded it (cover version).
