Sergio,

I've had a play around with the file 'Song with many erratic substyles.SGU'. I've generated it around a dozen times and it seemed to work fine each time.

To be honest, though, I don't know a great deal about substyles because I've never used them.

What I suggest is...

1. Generate and regenerate the backing until you get an instance where the changes are wrong and not happening as they should.

2. When the above occurs, freeze all the tracks.

3. Send the fully frozen SGU to PG Music and in your email, explain which bars are the problem bars and what should have occurred at these locations. Identifying these regions will help Support a great deal and make it much easier to investigate the issue.

Sorry I wasn't able to help more.

Regards,
Noel
