ADD MIDI CONTROL OUT EXAMPLE about cookbook

[NickCulbertson]

Which value are you wanting to send? If it is x or y you would place that as your data1 or data2 variable.

Evan made a midi out tutorial that might be helpful: https://youtu.be/gb1kcqpELeE

Hey Nick thanks for the quick reply!
watching your video I understand but I am slightly confused by how the XYslider from my code works and don't understand how to connect the x y value as data1 data2 (like you mentioned) also this function is working on button click but I am trying to send it when I use the XYslider ( would also have to convert those values as they are floats atm)

thank you for your help!

Button("Send Controller 5 - 127") {
let eventToSend = StMIDIEvent(statusType: MIDIStatusType.controllerChange.rawValue,
channel: 0,
data1: 5,
data2: 127)
if selectedPort1Uid != nil {
conductor.sendEvent(eventToSend: eventToSend, portIDs: [selectedPort1Uid!])
} else {
conductor.sendEvent(eventToSend: eventToSend, portIDs: nil)
}
}

// add the variables to your conductor class and access their didSet method. You’ll probably need to resolve some issues with the red stop sign that shows up in Xcode.
extension MIDIPortTestConductor: ObservableObject {
	@Published var x : Float = 0.5  {
        	didSet {
                        //Call MIDI method here
            		let eventToSend = StMIDIEvent(statusType: MIDIStatusType.controllerChange.rawValue,
				channel: 0,
 data1: Int(x*127),
 data2: 127)
                        conductor.sendEvent(eventToSend: eventToSend, portIDs: nil)
        	}
    	}
        @Published var y : Float = 0.5  {
        	didSet {
                        //Call MIDI method here
            		let eventToSend = StMIDIEvent(statusType: MIDIStatusType.controllerChange.rawValue,
				channel: 0,
 data1: Int(y*127), data2: 127)

                        conductor.sendEvent(eventToSend: eventToSend, portIDs: nil)
        	}
    	}
}

// Update the pad to read the variables from the conductor.
XYPad(x: $conductor.x, y: $conductor.y)
                    .backgroundColor(.white.opacity(0.25))
                    .cornerRadius(0)
                    .foregroundColor(.white)
                    .indicatorSize(CGSize(width: 30, height: 30))
                    .squareFrame(proxy.size.height / 5)

Thanks Nick!
Great example.
had to move things around a little bit but it works now <3
