To do that you have to have the master track "or a great cover band to rerecord" which no one will ever have unless you buy the rights. All customs are made this way. there is no way around it and you dont really tell the diff except the guitar doesnt cut out when you miss a note.
i have a question currently my atmos switch isnt picked up by pc on HOS but the cable and port do work with apx and tegra so i know the hardware is good, any clue?
