Hey guys!  
I’m swithching from WDL-OL to IPlug2 and I’m not having any issues with the vst2 versions of my plugins. But on the vst3 version the presets don’t work. When I select a preset, flstudio notices the preset change and even states the name of the preset like:

> **Beach Drums** (Internal) 2/6

But nothing happens, knobs don’t move and the plugin’s effect doesn’t change. I had added the following lines (in -win.props) to enable VST3 presets:

```auto
</BuildMacro>
<BuildMacro Include="VST3_PRESET_LIST">
  <Value>$(VST3_PRESET_LIST)</Value>
</BuildMacro>

```

Did I do it wrong?  
Am I forgetting something?  
Thanks a lot!

I don;t think you are actually setting the preprocessor macro.

I would add it here

> <https://github.com/iPlug2/iPlug2/blob/master/Examples/IPlugEffect/config/IPlugEffect-win.props#L6>

e.g. \<EXTRA\_ALL\_DEFS\>IGRAPHICS\_NANOVG;IGRAPHICS\_GL2;VST3\_PRESET\_LIST\</EXTRA\_ALL\_DEFS\>

I’ve allready tried that, but thanks for the help!  
It may be related to the way I implemented the parameters… Do you know maybe what functions are called when the preset is changed?  
thx

When I compile the VST3 version, I get an error after compiling:  
 ![image](https://global.discourse-cdn.com/free1/uploads/iplug2/original/1X/7f9db238cb18537afa11883c04e3a901be0ea927.png)  
The plugin doesn’t open but it gets compiled anyway and seems to work fine, so I never bothered. Could this be the reason the presets won’t work?
