Thanks Noel, not sure whether I need MP3 or wave.
I use MP3, as I use my IPad with Onsong which allows a backing track...unsure whether it has options on type. To date it's been drum tracks from Garage Band converted to MP3.
Will check if wave files play on iPads and Onsong.
I only play a few gigs every now and then so while I strive for the best sound with my gear, it's not the end of the earth if I have to compromise,
Cheers
