MIDISequencer

MIDI Sequencer that sends MIDI events to other apps. Built top on AKSequencer of AudioKit for iOS and macOS. Create smart MIDI sequencer instruments with just focus on notes.

Requirements

• Swift 3.0+
• iOS 9.0+
• macOS 10.11+

Install

ruby pod 'MIDISequencer'

Usage

MIDISequencer built top on AudioKit's AKSequencer with MusicTheory library to create sequences just focusing on notes with multiple track support.

• Create a MIDISequencer instance.

swift let sequencer = MIDISequencer(name: "Awesome Sequencer")

• Create a MIDISequencerTrack and add it to sequencer's tracks.

swift let track = MIDISequencerTrack( name: "Track 1", midiChannel: 1)

• Add some MIDISequencerSteps to track's steps

swift track.steps = [ MIDISequencerStep( note: Note(type: .c, octave: 4), noteValue: NoteValue(type: .quarter), velocity: .standard(100)), MIDISequencerStep( note: Note(type: .d, octave: 4), noteValue: NoteValue(type: .quarter), velocity: .standard(100)), MIDISequencerStep( note: Note(type: .e, octave: 4), noteValue: NoteValue(type: .quarter), velocity: .standard(100)), MIDISequencerStep( note: Note(type: .f, octave: 4), noteValue: NoteValue(type: .quarter), velocity: .standard(100)), ]

• You can even add chords or multiple notes or even both to any step.

``` MIDISequencerStep( chord: Chord(type: .maj, key: .c), octave: 4, noteValue: NoteValue(type: .quarter), velocity: .standard(60))

MIDISequencerStep( notes: [Note(type: .c, octave: 4), Note(type: .d, octave: 4)], octave: 4, noteValue: NoteValue(type: .quarter), velocity: .standard(60))

MIDISequencerStep( notes: Chord(type: .maj, key: .c).notes(octave: 4) + [Note(type: .c, octave: 4), Note(type: .d, octave: 4)], noteValue: NoteValue(type: .quarter), velocity: .standard(60)) ```

• Set isMuted property to true to mute any MIDISequencerStep.
