Using the Seq object in Gibber

seq.js

s = Synth();    // create a synth

// sequence a four note phrase
seq = Seq(["A4", "B4", "C4", "C#4"], _4); 

// tell the sequencer to control the synth. Using introspection,
// the sequencer knows it should call the note method of the 
// synth
seq.slave(s);

// Create a sequencer that randomizes the notes found in seq
// at the start of every measure
seq2 = Seq([seq.shuffle], _1);

// Create a sequencer that changes the attack of the synth
// every quarter note
seq3 = Seq([10, 100, 250], _4, "attack");
seq3.slave(s);
