Not really a tutorial, just some things to try to
get started.


Load Tutor1.LS
	*File -> Load Rule File -> tutor1.LS
This is a simple 2-d branching structure. 
	*Production -> Make
	*Interpretation -> Interpret
	*MIDI -> Play
Because the branches are all [] ('square bracket') pushes 
and pops, the melody remains monophonic. But the 'c' gives 
a variety of MIDI instruments playing.

Look at and run Tutor2.LS
	*File -> Load Rule File -> tutor2.LS
	*Production -> Make
	*Interpretation -> Interpret
	*MIDI -> Play
The rules now have a 'stochastic' component which
acts to branch unpredictably into a 3rd dimension.
Try changing the 'interpretation':
	*Interpretation -> Pitch -> (pick) Up z
        *Interpretation -> Duration -> (pick) Forward x
	*Interpretation -> Interpret
	*MIDI -> Play

Try Tutor3.LS:
	*File -> Load Rule File -> tutor3.LS
Now, one of the rules will branch 'polyphonically' because
of the {} (curly bracket) pushes and pops. Change one of the
c's in a branch to c(40). 
	*Production -> Rules -> (edit)
Mutate:	
	*Production -> Mutate
(This may require more than one attempt to do actually change
anything)
	*Interpretation -> Interpret
	*MIDI -> Play
