AKOutputWaveformPlot of AKNode in a different class?

[Michael Samuels]

Hi folks,

I'm having some trouble with AKOutputWaveformPlot. 

I have a project with an AudioKit synthesizer built in a class called Synthesizer.swift, and a UI controlled by SynthesizerViewController.swift. SynthesizerViewController.swift creates an instance of Synthesizer.swift. 

I'm trying to include an AKOutputWaveformPlot of the output from Synthesizer.swift in my View Controller. I am able to create the AKOutputWaveformPlot view, add it as a subview, etc., all no problem. However the WaveformPlot does not seem to register any input (i.e. from the instance of Synthesizer.swift). It remains blank/lifeless. My guess after trying a few things is that this is because Synthesizer.swift is a different class (by the way, Synthesizer.swift is declared with type AKNode).

I'm wondering if there's an additional step I need to take (like passing my "synthesizer" instance to AKOutputWaveform Plot as a parameter... except it doesn't take a parameter besides frame... I could also change over to AKNodeOutputPlot?)

My best guess is that I'm supposed to declare another instance of AKOutputWaveformPlot inside of Synthesizer.swift, and then assign wavetable = synthesizer.waveform in my ViewController, but this presents a different problem: I have to pass the Synthesizer.swift instance of AKOutputWaveform a frame, but the frame is only defined in the ViewController.

Any help would be much appreciated...

class SynthetizerViewController : UIViewController, VerticalTabBarControllerEmbedded, AKKeyboardDelegate {

...
    var synthesizer = Synthesizer()

    var wavetable: AKOutputWaveformPlot!

   
...

override func loadView() {

       

       super.loadView()


     let wavetable = AKOutputWaveformPlot()

        wavetable.plotType = .buffer

        wavetable.backgroundColor = .red

        wavetable.color = .blue

        wavetable.shouldCenterYAxis = true

        view.addSubview(wavetable)

        wavetable.snp.makeConstraints { make in

            make.top.equalTo(device1View.snp.top)

            make.left.equalTo(device1View.snp.right).offset(5)

            make.right.equalTo(device2View.snp.left).offset(5)

            make.bottom.equalTo(device1View.snp.bottom)

        }

        //self.wavetable = synthesizer.waveform

        self.wavetable = wavetable

...

override func viewDidLoad() {

       super.viewDidLoad()

   // wavetable = self.synthesizer.waveform   (My best guess? but declaring another instance of AKOutputWaveform in the synthesizer class presents its own problem: I need to pass a frame, which is only specified in SynthesizerViewController.swift)
