Timer Start/Stop based on external input (Gain value)

[HISEnberg]

I am working on an animation based on the gain value and for the sake of CPU I want the animation to stop running based on if there is any gain input or not. I am actually not sure what would be more/less CPU intensive here (leaving the timer running, or starting and stopping it based on input activity), but it does bring up an interesting challenge on how to start and stop a timer based on an external input.

I was not able to use the startTimer/stopTimer in order to accomplish this. So I thought about using a second Timer to monitor for changes. This is counterintuitive however as it leaves a second timer running. Part of me thinks perhaps a broadcaster might work better for this purpose. Does anyone have a suggestion?

const var TimerMainAnimation = Engine.createTimerObject();
const var MonitorGainTimer = Engine.createTimerObject();
const var Gain1 = Synth.getEffect("Gain1");
const var knb_Main = Content.getComponent("knb_Main");

var silenceCounter = 0;
const var SILENCE_THRESHOLD = 17;
const var SILENCE_LEVEL = 0.001;

TimerMainAnimation.setTimerCallback(function() 
{
    var GainL = Gain1.getCurrentLevel(0);
    var GainR = Gain1.getCurrentLevel(1);
    var GainSum = (GainL + GainR) / 2;

    knb_Main.setValue(GainSum);

    if (GainSum < SILENCE_LEVEL) 
    {
        silenceCounter++;
        if (silenceCounter >= SILENCE_THRESHOLD) 
        {
            TimerMainAnimation.stopTimer();
            Console.print("Timer stopped due to silence.");
        }
    } 
    else 
    {
        silenceCounter = 0;
    }
});

MonitorGainTimer.setTimerCallback(function() 
{
    var GainL = Gain1.getCurrentLevel(0);
    var GainR = Gain1.getCurrentLevel(1);
    var GainSum = (GainL + GainR) / 2;

    if (GainSum >= SILENCE_LEVEL) 
    {
        TimerMainAnimation.startTimer(30);
        Console.print("Timer running" + " | Gain Value: " + GainSum);
    }
});

MonitorGainTimer.startTimer(100);

@d-healey Ah thanks that is what I figured and had originally, I must have had a typo. Here is a solution for anyone else who lands here:

Content.makeFrontInterface(600, 600);

const var SimpleGain1 = Synth.getEffect("Simple Gain1");
const var Knob1 = Content.getComponent("Knob1");


const t = Engine.createTimerObject();

t.setTimerCallback(function()
{
	var Gain = SimpleGain1.getCurrentLevel(false);
	Console.print(Gain);
	if (Gain <= 0)
	{
		Console.print("Stop");
		this.stopTimer();
		Knob1.setValue(Gain);
	}
	else
	{
		Console.print("Timer is running");
		Knob1.setValue(Gain);
	}	
});

Still bugging for me in my current project. I am using 4 channels which I think is causing issues.

[d.healey]

@HISEnberg run a loop to check all channels.

[HISEnberg]

@d-healey It's strange it isn't the channel count either. I can't really put my finger on it since I load the snippet into the same project, change the channel amount and it works fine. It is just my current .xml that it won't work in, and it isn't like I am reusing any of the variables or anything (I commented out all my other code to test). I am just going to sit on it and address it later.
