I have this problem also - volume
and swell. It seems to be on old files - in my case hundreds of tunes. It really is a very big change of volume for the hold.

When I first noticed it, I reduced the volume on shots and holds back to zero - I don't think the default was zero, Mack. All mine were +10 or +5, unless that was picked up from my old 2013 version. However, this did not help with the existing song files. The songs I have created since I updated to 2014 do not seem to have the problem.
What
is a problem is that most of my files seem to need volume remixing and that is a disaster.
