The way I see it is that it is confusing
Firstly, we have track names. A name can be DRUM or DRUM-FOO. If I could go back in time, apart from solving world peace, I would have done this differently. But, for now we have to accept that a name can be DRUM or DRUM-FOO.
Secondly, we get into types. The types are DRUM, CHORD, etc. and they should not be confused with names.
So, gettng back to the docs ... Probably having the line read:
You can use the command with or without a track modifier/name (depending on the context) as the second
argument:But, thinking more I'm thinking that the section should be replaced with:
Everything after AllGrooves is interpreted as a legitimate MMA command.
AllGrooves Volume p
or
AllGrooves Chord Octave 5
A warning message will be displayed if the command had no
effect.
