I'm an instrumental musician (guitar). At gigs I play over backing tracks I create with BIAB and my DAW (Logic).
I perform using mp3 files on my ipad or iphone. I usually take both IOS devices to a gig so I have backup

I use anytune Pro for setlist and playback management. Its great software gigging.
It has a variety of features (loop sections, part markers, etc) that i find especially useful
I can easily change tempo and key if I need to.

I also use a Irig Blueboard Bluetooth midi pedal to control Anytune. This gives me the ability to start/stop, next/previous tune, loop on/off, etc commands from a foot pedal. Brilliant.

Depending on the venue I either use bluetooth to or cables connect from the ios device to the PA. I always make sure i have 2 sets of cables just in case.

I am unaware of a simpler yet more powerful setup for this type of gigging. If you find a better approach please let me know.
