Just UI stuff, really.
Probably won't have time for real hacking until christmas break.
Amplitude control is linear over notes.
The user can turn sequences into
'synthetic instruments', sort of.
Names are like the usual [a-zA-z_]+.
Note specifications are [A-G](b|#)(\++|-+)?
Store synthetic instrument as name:note.
If name:C exists, you can play it on any note;
the default is to just transpose. Otherwise it works
like table lookup. Amplitude changes apply in the
obvious way; though noticably a linear application
to the whole sequence can be broken up into linear
application to each note in it, so that all the
perl really needs to feed to the C is individual
notes. I think if you play a synthetic instrument
'as' a square wave, say, it just adds 2 modulo 4
to all the instrument settings in the sequence.
Oh, also if the duration of the 'note' is different
than the sequence, either clipping or repetition
(or both) takes place, *not scaling*. This preserves
