That is helpful.

Here’s something else I could use help with.  The person who wrote Midi_note 
decided that a negative (“unknown”?) Audio_dynamic should be treated as 90/127, 
whereas the person who wrote Midi_dynamic decided that a negative Audio_dynamic 
should be treated as 100/127.  Unless there is a good reason for this 
inconsistency, I would like to move the default into Audio_dynamic itself; but 
I’m not sure which value to use.  Are these specific values important, or are 
they just two individuals’ fingers in the wind?

Apart from that, I think it would be a good idea to rename the music property 
midi-extra-velocity to relative-volume and change its range to [-1,1] to match 
the scale of the context property dynamicAbsoluteVolumeFunction instead of 
being MIDI-specific.  Are there any objections?
