an API to simplify MIDI message generation
[](http://travis-ci.org/carlos8f/node-midi-api)
Examples
--------
### Playing chords
```javascript
var coremidi = require('coremidi')
, midi = require('midi-api')()
.bank(2)
.program(33)
.rest(500)
function maj7 (root) {
midi
.noteOff()
.noteOn(root)
.noteOn(root + 4)
.noteOn(root + 7)
.noteOn(root + 11)
}
maj7(44)
midi.rest(200)
maj7(45)
midi.rest(200)
maj7(46)
midi.rest(200)
maj7(47)
midi
.rest(1000)
.noteOff()
.rest(400)
midi.pipe(coremidi())
```
### Playing scales
```javascript
var coremidi = require('coremidi')
, midi = require('midi-api')()
.bank(2)
.program(4)
.rest(500)
function scale (root) {
var scale = [ 0, 2, 2, 1, 2, 2, 2, 1 ]
, backwards = []
;(function next (pitch) {
if (scale.length) {
var interval = scale.shift()
backwards.push(interval)
pitch += interval
}
else {
var interval = backwards.pop()
if (!interval) {
midi
.rest(400)
.noteOff()
.rest(500)
return;
}
pitch -= interval
}
midi
.noteOff()
.noteOn(pitch)
.rest(200)
next(pitch)
})(root)
}
scale(60)
scale(61)
scale(62)
scale(63)
midi.rest(500)
midi.pipe(coremidi())
```
