MIDI Sequencer for iOS on swift.
R9MIDISequencer now features a full MIDI Sequencer with EXS24 and SoundFont samplers which can be tied to your instruments for awesome, accurate playback.
Play note using the sampler:
import R9MIDISequencer
let url = NSBundle.mainBundle().URLForResource("Sound Font File",
withExtension: "sf2")
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:
let sequencer = Sequencer(sampler: sampler, enableLooping: true)
let midiUrl = NSBundle.mainBundle().URLForResource("MIDI File",
withExtension: "mid")
sequencer.playWithMidiURL(midiUrl)
Callback from MIDI message
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) {
