Some thoughts/suggestions

[dflat]

1. There appears to be a bug somewhere that seems to set the "number of times" to a very large number, normally 333 or 999 times.

the bug should be fixed. Unfortunately for any song that might have been set to 999 in the previous version you would probably have to manually set it back down. After this, it should not be able to go past 50. This was a reasonably rare bug so hopefully not too many songs were set to this.

2. If you do allow a song to loop many times it seems that eventually the chords played get out of sync with the drums.

This should have been fixed also. Make sure you have updated to the current version of iReal b v2.8 in the App store.

4. The Am7#5 doesn't seem to be recognised.

You could use Am#5.

Thanks for your support and thoughts Colin.
