zsnd-core

Copperbox revision 2486.

I've added composition operators - scoOver, scoBeside - to combine scores and hopefully debugged the score output code that was stopping them work correctly.

Update - revision 2487.

I've changed the score output so it now works for both overlay and sequential append. I'm not entirely happy with the generated scores as they probably aren't very efficient Csound, but they will do for the time being.

I've removed the Onset notelist - it had bad properties that weren't easy to rectify so its removal seems better. It is superseded by TraceLoc, which doesn't suffer from the same problems though it is more limited as a structure.

Updates to work  with ZSnd-Core changes.

Note, OnsetNotelist has a bug where the placement of notes is wrong after a tempo change - while I've identified where the bug lies, I'm currently stumped as to how to fix it...

I've remade the score datatypes so they are closer to the picture datatypes in Wumpus-Core - scores now have a Timespan (analogue to a bounding box) and a frame that abstracts the first event time. This allows scores to be moved cheaply so I can implement "picture language" like operations to combine scores.

Following up the last commit, I've added table-offset  to the monadic builder so table indexing within an instrument is parametric. Generally numbers will be contiguous within an instrument from some start point.

Copperbox revision 2481.

I've changed table references (in Csound fields named ifn or similar) so they are distinct from ports in the syntax. This is should improve the modularity of Inst definitions which were otherwise liable to have table number conflicts when multiple instruments were used.

Note, I still have to improve the build monad so it treats table numbers as offsets rather than absolute values.

Copperbox revision 2480.

Preliminary work on pitch / scale support. I've replaced the PitchClass module with one for 12 tone EqualTemperament and added a module for Kraig Grady's Centaur scale - I want to consider alternative scales from the start rather than shoe horn them in later.
