For those auditions that require your accompaniment on a CD (Unifieds), how does one go about getting that done? I am not very technologically savvy and don't know the process for getting someone to play the accompaniment for my son's audition pieces and getting that on a CD. Is it necessary to have a digital piano that has that capability? Also, I read on here somewhere the suggestion of putting your warmups on your Ipod and warming up in the car, hotel room, remote hallway, etc. How is that accomplished?
