Here is my note-by note understanding of the solo snare-on dynamic key assignments. This is from page 36 of the VI percussion manual. Am I reading it correctly? The differences in the dynamic level are sometimes difficult to hear.
C#7 strong 0.5 seconds. ( black key )
D7 medium 0.5 seconds ( white key )
D#7 strong 1 second ( black key )
E7 medium 1 second ( white key )
F7 medium 2 seconds ( white key )
F#7 strong 2 seconds ( black key )
G7 medium 4 seconds ( white key )
G#7 strong 4 seconds ( black key )
A7 medium 8 seconds ( white key )
A#7 strong 8 seconds ( black key )
