I apparently had this same issue in 2014....I found a thread I posted re midi transpose issue, but never got a reply.  Happening again

I loaded an ALL file from 2014 to edit several old songs.  I’ll give one example of my problem.  A song I wrote in Am, is now playing in Abm.  The only reason I can think is that a few yrs back I had my master settings down 1/2 step to accommodate our vocalist in the band.  I may have recorded these songs that way.  Master tuning is back to normal.

In the song mode, I transposed up 1/2 step to Am and made some changes, but of course the playback was not in key. Apparently I need to make any changes in Abm.
Anyone know how I can get these songs back to original key?

SOLVED.  Used JOB NOTE TRANSPOSE. And raised every track 1/2 step.  Except the drum track.
