Right you are, Marko. I find, to my embarassment, that my early attempts at saving the style failed because of user error (stupidity?). I was confused when their was a notation right above the SAVE button that said "bar 1". Because when I "saved" and then tried reloading, the style was all messed up and I figured I had only saved part of it. I tried saving again today and found the same problem, BUT also noticed that the accompaniment button had been turned off. When I turned it back on, everything was fine, including the new volume settings. So, the Digital Recording can be used to Save changes in the style volume, but this, like some other options, is not so clear in the manual.
