Thanks for the report. Immediately I had a lot of trouble with this library trying to get its faceplate and backplate to show up, they have a transparent faceplate overlaid on the backplate.

Does the MM support syntax like this?

Similarly, panel-\>addLayer doesn’t seem to work

I had to write a workaround for the above just to get one of the layers to load:

```auto
	#ifdef METAMODULE
	setPanel(panel);
	if (bHasCommon) {
		SvgWidget* overlay = createWidget<SvgWidget>(Vec(0, 0));
 		overlay->setSvg(APP->window->loadSvg(asset::plugin(pluginInstance, "res/" + moduleName + "_common.svg")));
 		addChild(overlay);
	}
	#else
	if (bHasCommon) {
		panel->addLayer("res/" + moduleName + "_common.svg");
	}
	setPanel(panel);
	#endif

```

Re: aestus, looks like working as intended. It has this knob that’s labeled `Module model` but it only has two discrete states which get shown in that view.

Oh, I see it now, right.

I’ll look at the addLayer thing. It looks like the workaround you used is just using `addChild` instead of `addChildBelow`? And also explicitly setting the box.pos to Vec(0,0) (which is probably important to do)

Update: I see now, your workaround calls `addChild()` to the ModuleWidget, and the original code calls it to the SvgPanel FrameBufferWidget.

OK, I see what’s happening. There are three PNGs it’s trying to overlay with transparency. What we need to do is make the background one the panel (since that’s always the first/lowest layer), and then make the other two SvgWidget children of the ModuleWidget.

I tested it out, seems to work? (just in the simulator I didn’t bother fixing the font):

It would faster to load and less memory consumed to combine those three images into a single PNG. Not a huge deal, but something like imagemagick could be scripted to do all the modules in one command.

I’ll push how I did it.  
Update: pushed to branch `faceplate-fix`

I also made the same fix around the same time as you lol

I’ve updated the repo with font fixes, and also laid out the labels a bit better so they dont overlap on the MM.

I had to truncate some of the labels just as they are really hard to place anywhere at a reasonable font size.

Updated again today - I reduced some of FFT/window size for MM on the Spectral modes for Fluctus and Etesia. So now the “STRETCH” and “SPECTRAL” modes can run on 48khz 256 buffer size.
