Increase volume of MDL drums

The new marching percussion sounds in beta 2.3 are a great start, but it would be nice if you could increase the base volume of them to make them more audible in a loud setting, such as a marching band score.
Increasing the volume of the drums in the mixer helps slightly, but it does not do very much, and it's not that user-friendly to turn up each drum individually and turn down each wind instrument individually.
It all comes down to personal preference, but I think it would be easier to make the volume of the new sounds match the old ones from previous version (a score is attached showing an example of each)
