Three of my song fades are garbling for some reason, and I am trying to figure out why.

If you listen to the last 10 seconds of each, the volumes are all over the place instead of a nice fade out (volume meaning audible, faded using expression, CC #11).

For this soundtrack, there are 13 songs total.  The other 10 songs fade out fine.

I've checked the event view in Sekaiju and there are no stray expression values that are above the "fade" line, and everything looks okay at first glance.  I thought maybe it was being affected by CC #43 (fine tuning for expression) but the other tracks all have "level" CC #43 during the fadeout with no issues.

I load the file in Cakewalk (well, Sonar now :/) and apply the fade using a CAL script after I cut the file to length.  Usually it works fine, but for some reason, not with these particular files.

One caveat, that is very difficult for me to check, is that there are 8 channels of percussion, and each of the 3 percussion instruments play on all 8 of the channels, alternating.  Same with melodic instruments, 8 channels with every instrument playing across all 8 channels, alternating.  So perhaps the different tracks' values are interfering with one another?  And if they are, how can I compensate?
