# R9MIDISequencer

MIDI Sequencer for iOS on swift.

# Feature

## Sequencing

R9MIDISequencer now features a full MIDI Sequencer with EXS24 and SoundFont samplers which can be tied to your instruments for awesome, accurate playback.

## Example Code

Play note using the sampler:

```swift

import R9MIDISequencer

let url = Bundle.main.url(forResource: “Sound Font File Name”,

        withExtension: "sf2",

        subdirectory: "Sounds")

        

let sampler = Sampler(bankURL: url!, program: 0, bankMSB: 0x79, bankLSB: 0, channelNumber: 1)

// Play the note C

sampler.startNoteWithNumber(36)

// Play the note G

sampler.startNoteWithNumber(43)

```

Play MIDI file using the Sequencer:

```swift

let sequencer = Sequencer(sampler: sampler, enableLooping: true)

let midiUrl = Bundle.main.url(forResource: “MIDI File",

        withExtension: "mid")

sequencer.playWithMidiURL(midiUrl)

```

Callback from MIDI message

```swift

class GameScene: SKScene, MIDIMessageListener {

    override func didMoveToView(view: SKView) {

        

        ...Initialize sampler

        

        let sequencer = Sequencer(sampler: sampler, enableLooping: true)

        sequencer.addListener(self)

        

        ...Play MIDI

        

    }

    

    func midiNoteOn(note: UInt32, velocity: UInt32, channel: UInt32) {

        // Call back of note on message.

    }

    func midiNoteOff(note: UInt32, channel: UInt32) {

        // Call back of note off message.

    }

    func midiSequenceDidFinish() {

        // Call back of finish MIDI sequence.

    }

}

```
