Hi, and thanks for experimenting with it.

The attenuation is based on the attenuation modulator it seems like. It 
ranges from 0.1 to 1440, where 1440 is the softest ( -96 dB) and the 
calculation is (volume_score / attenuation).

There are default modulators in a soundfont for making the MIDI note 
velocity as well as CC 7 (main volume) and CC 11 (expression) affect the 
attenuation, but this can be overridden by the soundfont.
