Mini-language for music notation. Originally developed for live coding.

Accumulator. Based on Andre Bartetzki's CMask.

Break-point functions. Based on Andre Bartetzki's CMask.

Generator Combinators.

Score operation functions for translating, scaling, repeating, and merging
serial and parallel parts. Also for calculating durations. Assumption about
score note format are described in each function's documentation.

Functions for modeling Performers (based on Steven Yi's Python Orchestral 
Composition Library).  Uses 8 pfield format:

p1 - instrument 
p2 - start time
p3 - duration
p4 - pch1 
p5 - pch2
p6 - amplitude
p7 - space (Left: -1.0, Right: 1.0)
p8 - articulation

Score note should leave out p1, to be filled in by Performer.  

Functions for modeling Performer Groups (based on Steven Yi's Python 
Orchestral Composition Library).

"...sieve theory is the study of the internal symmetries of a series of points 
 either constructed intuitively, given by observation, or invented completely 
 from moduli of repetition." - Xenakis, Formalized Music, pp. 276 
 
 Sieve functions based on work by Iannis Xenakis. Sieves are represented as
 a 2-vector of [modulo index].  U and I are used to create Union and
 Intersection Sieves. Sieves may also be nil, though are factored out when a
 Sieve is simplified, and generates no sequence when gen-sieve is called.
