ABCplayerCodea v0.2.1

Main.lua

-- ABCplayerCodea version 0.2.0
-- Plays ABC musical notation format tunes on the Codea/Codify iPad platform. 
-- By Fred Bogg, November 2011.  Improvements welcome. Thanks to ipda41001 for coding assistance.
-- This program defines musical notes and chords, parses an ABC format tune, creates a table
-- of notes to be played with their durations, and then plays it.  With the parsing done 
-- first, playback is possible without slowing down draw frames (psuedo-background).

-- 0.2.0
-- Uses new sound() API based on sfxr
-- Tunes can play independently
-- made tempo independent for each tune
-- parses comments

-- 0.1.9
-- bug fixes and stuff

-- 0.1.7
-- Added flats
-- Implemented key signatures
-- Improved parsing of rendered MIDI files

-- 0.1.6
-- New sharps
-- Starting to implement key signatures
-- Improvements to pattern matching

-- 0.1.5
-- Put class functions in separate tab, data in separate table.
-- Crazily moved tempo iparameter to createSoundTable() to set default to the tune tempo. 
-- Added loop argument to ABCMusic. 

-- 0.1.4
-- added fromTheTop() (a rewind)
-- added demo touched function to demo fromTheTop()

-- 0.1.3
-- Added sharps to central octave.

-- Use this function to perform your initial setup

    -- Instantiates the class using the tune. arg 1 for loop, arg 2 for debug, arg 3 dumps
