AKCallbackInstrument midiIn and status on callback not working

I have upgraded AudioKit to 4.6.1 and now cannot compile my application. 2 issues came up are connected to the AKCallbackInstrument class.

first:

callbackTrack?.setMIDIOutput(callbackInstrument.midiIn) which comes up with Value of type 'AKCallbackInstrument' has no member 'midiIn' which is wiered because AKCallbackInstrument inherits from AKMIDIInstrument

second:

callbackInstrument.callback = { status, noteNumber, velocity in
    if(status == .noteOn){
        // ...
    }
}

this notes: Ambiguous reference to member '==' , this isuue I saw on SO already but nothing helped.

Thanks :)

Because I got few questions personally I'll post here what worked for me as an accepted answer.

change AKCallbackInstrument with AKMIDICallbackInstrument and the API should work as expected.

* Please make sure you use a version that is newer than 4.6.1 as fixes and changes to MIDI components were made in this version release.

This looks like it is due to the change from MIDIStatus being a type to MIDIStatus being an object contain a type. 

public struct AKMIDIStatus {
    ...
    public var type: AKMIDIStatusType? {
        return AKMIDIStatusType(rawValue: Int(byte.highBit))
    }

So, try just changing your code to s

if status.type == .noteOn {
    //
}
