Main Stage plays random Playback Tracks on Patch List

Hey Guys,

I'm Pat and I'm using Mainstage for several gigs as a keyboarder. Yesterday I had a show where most songs are supported by additional backing tracks to make it sound bigger.

Everything during soundcheck was cool. I left everything open, went off stage and when I started the show from the patch list, everything was messed up.

For example the track I imported for Song No 1, suddenly was exchanged with the one from Song 8. When I tried to start Song 2, it played the backing track from another song.. The whole patch list was messed up..

So what I had to do was to search for the tracks in FINDER and played them through QUICK TIME player, while the lead singer did some talking with the audience. It was a big struggle for me.

Anyone had some similar problem?

Best,

Pat
