I agree that iPads or even an iPod Touch are great for triggering live performance tracks. I use TwistedWave for iOS which is much, mush faster for this than Apple Music/iTunes/Memos etc. The problem with an iPhone is that you need it in Airplane Mode or a call or text can screw you up if received during performance.
Yes indeed.
People tend to learn that gotcha pretty quickly.
Even an email receipt or text receipt alert can get in the way.
Its pretty easy to deal with. You just need to remember.
I use a tablet for performance with the phone handy as a backup.
I've used the phone a couple of times just to see how it worked.
Perfect.
Same software/data on both. Anytune Pro. Bluetooth pedal works on either device.
Often I just use bluetooth to connect my tracks to a mixer or powered speaker.
