Fix for Bug [777589] SIMON1: Sound volume strangeness

Browse Source 
Fixed redundant, cumulative adjustments of _masterVolume
on the individual channel volumes. This fixes problems
with individual instruments changing volume by too much,
or dropping out altogether, when changing the master
music volume.
