step-sequencer

An EventEmitter-based step-sequencer for Node.js.

Usage

var StepSequencer = require('step-sequencer');

// Instantiate a new StepSequencer object
var stepSequencer = new StepSequencer(120, 4, [0, 1, 2, 3]);

// The StepSequencer emits the number of
// the step when that step is to be played
stepSequencer.on('0', function (step) {
    console.log(step);
})
.on('1', function (step) {
    console.log(step);
})
.on('2', function (step) {
    console.log(step);
})
.on('3', function (step) {
    console.log(step);
});

// Begin playing the sequence
stepSequencer.play();
// 0
// 1
// 2
// 3 ...

Methods
