After I changed over to Sierra OS.

Now In BIAB the chord highlight, showing the current chord of the song, is randomly out of sync, jumping around and stalling out. Very frustrating and making BIAB almost unusable.

This is the only problem I have seen with Sierra, all other programs are working fine. It does it on every song I try to play in BIAB. Sometimes the chord highlight stalls out/ freezes for 5 or 6 measures. Does anyone have any idea what is going on here? Maybe a complete fresh install?

Thanks
