Hi Geoff thanks for the tip.

I had one sandisc extreme pro card at home so i gave it a try.  (Firing with cannons on sparrows )
The card i normaly use is an sandisk ultra. I think its a little bit better but crashes are still easy to reproduce.
But i noticed something: My to go display mode is vertical scrolling. The most crashes happen when the song loads and the second page is loading at the bottom of the screen. Before the second page is showing up MSP crashes.
I have to say the are also a lot of annotations in this songs. Sometimes only the annotations from the fist page are showing up and not the pdf behind.

So i switched to one page only and it runs much better. I think the loading of the second page (ore eventually more in the background) causes the crash.

Edit: but after one practice session still a lot of crashes....
