Audiokit Seems to Receive Only The First Three Numbers of Sysex Midi Messages

AKMIDIListener not receiving SysEx

EDIT: Thanks for bringing this to our attention. The SysEx receiving issue has now been fixed in the develop branch of AudioKit: https://github.com/AudioKit/AudioKit/pull/1017

Instead of

NSLog("SysEx \(data)")

Have you tried?

if let sysExCommand = AKMIDISystemCommand(rawValue: data[0]) {
   print("MIDI System Command: \(sysExCommand)")
}

AKMIDISystemCommand will convert your SysEx data to something a bit more usable and is defined as follows:

public enum AKMIDISystemCommand: MIDIByte {
    /// Trivial Case of None
    case none = 0
    /// System Exclusive
    case sysex = 240
    /// Song Position
    case songPosition = 242
    /// Song Selection
    case songSelect = 243
    /// Request Tune
    case tuneRequest = 246
    /// End System Exclusive
    case sysexEnd = 247
    /// Clock
    case clock = 248
    /// Start
    case start = 250
    /// Continue
    case `continue` = 251
    /// Stop
    case stop = 252
    /// Active Sensing
    case activeSensing = 254
    /// System Reset
    case sysReset = 255
}

Porting a win32 MIDI SysEx application to MacOSX

I found a great little (just one .cpp file + headers) midi library - crossplatform and all :)

It's also a great source to analyse and to learn from.. a little nugget in the whole undocumented field.
