I have been messing with it and it seems to work (sort of). If I do a 'change by' plus 127 it increases the volume by 10 or 15. If you wanted a dramatic increase in volume, it would take several bars at +127 each to get there (I think you can do multiple 127's). It will require a lot of trial and error to get the volume increase that you really want. I was expecting to see what we had a view builds back when if you did a 'change by' it would show that exact increase in the mixer panel. I don't remember which build that was and I will have to go back and try to find the songs I worked on then to see if they play differently now. So I guess my current question is 'Is the current configuration PGMusic's desired method?'
