SHMIDIKit

A lightweight MIDI framework for iOS and macOS

Installation

SHMIDKit is written in Swift 4.2, so your code has to be written in Swift 4.x due to current binary compatibility limitations.

CocoaPods

To use CocoaPods add SHMIDIKit to your Podfile:

pod 'SHMIDIKit'

Then run pod install.

Examples

Import SHMIDIKit to your project

import SHMIDIKit

Get the MIDIHandler singleton

let midiHandler = MIDIHandler.shared

Create a virtual midi source and send out a MIDI message

let midiHandler = MIDIHandler.shared
// create a virtual MIDI source
midiHandler.configDevice()
// send message to the first midi channal
let channel: UInt8 = 0
// note number for middle C
let noteNumber: UInt8 = 60
// velocity (0 - 127)
let velocity: UInt8 = 90
// send the noteOn message out
midiHandler.sendNoteOn(channel: channel, noteNumber: noteNumber, velocity: velocity)

Send out a pitchbend message

let midiHandler = MIDIHandler.shared
// create a virtual MIDI source
midiHandler.configDevice()
// Value for pitchbend: 0 = Lowest position, 64 = Middle position, 127=Highest Position
midiHandler.sendPitchBend(value: 127)

Send out a sequence of control message

let midiHandler = MIDIHandler.shared
// create a virtual MIDI source
midiHandler.configDevice()
// get the cc number for Pan
let pan = MIDIController.Pan.rawValue
// Pan your sound to the left
midiHandler.sendControlMessage(cc: pan, value: 0)
// Wait a second
sleep(1)
// Pan your sound to the right
midiHandler.sendControlMessage(cc: pan, value: 127)
usleep(1)
// Return your pan to the middle
midiHandler.sendControlMessage(cc: pan, value: 64)
