Ipad goes to sleep in middle of song

I searched on every forum on internet and eventually end up fixing this by modifying the Auto-Lock setting on your iPhone.

In theory it should not sleep if you have a song chart in view. (It should sleep if you have the Song library or Settings page etc. showing instead).
You can test by selecting a very short sleep time as a test.
Try a reboot.
Otherwise: Back up songs (iReal Pro Settings > Backup), uninstall the app, reinstall (then restore songs from your backup).
