The extension looks very good, but I would recommend adding two 
important units - semitone and cent (in case anyone doesn't know, a cent 
= 1/100 of a semitone). Semitones - useful for osc transpose in synths, 
as well as shift amount in pitch shift modules. Cents - useful for 
relative detune in synths. I think those are much more common than, say, 
miles :)
