@d-healey I don't know how to send it as an attachment so here are it is as text:

============== VuMeter.js ====================

namespace VuMeter
{
/** Creates a peak meter.
*
* Usage: Give it a reference to a module (either synth or effect).
*
* It looks best using a width and height with multiple of 4.
* Customize the colours using the scriptPanel colour Ids
*/
inline function createVuMeter(name, x, y)
{
local widget = Content.addPanel(name, x, y);

	Content.setPropertiesFromJSON(name, {
	"width": 32,
	"height": 100,
	"itemColour": 0xFF90FFB1,
	"itemColour2": 4279505940,
	"bgColour": 4279505940,
	"textColour": 4283782485,
	"saveInPreset": false,
	"opaque": 1
	});
	
	widget.setPaintRoutine(function(g)
	{
		g.fillAll(this.get("bgColour"));
		
		g.setColour(this.get("itemColour"));
	
		var lsize = parseInt(this.data.lvalue * (this.getHeight()-4));
		var rsize = parseInt(this.data.rvalue * (this.getHeight()-4));
	
		g.fillRect([2, this.getHeight() - lsize - 2, (this.getWidth()-4)/2-1, lsize]);
		g.fillRect([2 + this.getWidth() / 2 - 1, this.getHeight() - rsize - 2, (this.getWidth()-4)/2-1, rsize]);
	
		g.setColour(this.get("itemColour2"));
	
		for(i = 1; i < this.getHeight()-1; i = i + 3)
		{
			g.fillRect([1, i, this.getWidth()-2, 1]);
		}
	});

	widget.setTimerCallback(function()
	{

		var rvalue;
		
		if(this.data.fx)

			lvalue = getNormalizedPeakValue(this.data.fx.getCurrentLevel(0));

	});

	widget.startTimer(30);
	return widget;
};

inline function setModule(vuMeter, module)
{
	vuMeter.data.fx = module;
}

inline function getNormalizedPeakValue(gain)

	return 0.01 * (100.0 + Engine.getDecibelsForGainFactor(gain));
}

}

@jay Can't test your snippet, you're using an external file called VuMeter.js.
