this is a set of classes & utils, with the goal of composing midi-based music in ruby in a concise, readable, and expressive manner

Overview of classes: Phrase: this is used to represent a simple line of melody, drum beat, or chord progression. important properties are: length, representing the 'count' of the phrase in beats, and notes, a list of hashes representing notes that are played in the phrase the hash is of the form: {:note=> , :len=> , :from_start=> , (optional) :vel=> } example: {:note=>64, :len=>4, :from_start=>0} will represent a whole note, played at the beginning of the measure {:note=>72, :len=>0.5, :from_start=>1.5} will be the same note, an octave up, with an eigth note duration, halfway into the second beat (one-and two-AND...) a phrase also has a 'channel', representing its midi channel. (usually 0, drum tracks use channel 9) A phrase can be built manually, the Phrase.build method allows for more convenient construction.

Score this is a collection of tracks, each of which has an array of phrases. it can be conveniently built with Score.build

ScoreWrap: this translates the ruby class 'Score' into a form usable by the java sequencer. It subclasses javax.sound.midi.Sequence for this purpose. TrackWrap: represents a single midi 'track' in a midi sequence. subclasses javax.sound.midi.Track One caveat: the javax.sound.midi.Track has a protected constructor, it may require some hacking around to get TrackWrap to run
