Hello,  
we have tested using JUCE 6.1.1 and the problem of transmitting parameter values when presets change on a VST3 plugin (ie U-He Diva) have been fixed. Great!

The problem of linking the wrong parameter in U-He Diva AU remains. We tested using the latest version of DIVA. However, now it links different wrong parameters than it did using JUCE 6.1.0. We weren’t able to replicate this issue with other plugins so far.

I’ve added a fix for this issue here:

> <https://github.com/juce-framework/JUCE/commit/0a288fc71e4f0ea726bf16a2275de083e9302f29>
>
> This issue could be seen when modifying the "OSC FmModSrc" parameter of
> U-He Div…a AU from the custom editor in the AudioPluginHost. The
> parameter display in the generic parameter editor did not update
> properly because the wrong parameter was marked as changed.

Please try this out and let us know if you encounter further issues.
