Hi Noel,

I tried all of your suggestions. I even uninstalled & reinstalled RB.
The master volume in Hyper Canvas would go to zero at the first count in.
Sometimes the master volume would go up & down randomly.
The only thing that worked was to delete the 1st 2 bars of each midi file.
I have no idea why this would happen on separate files, that played okay before...

There were no events showing in the tracks causing this.
