@d-healey I cannot reprocue this anymore. It happens a whole day, and now that I was going to make a video I cannot reproduce the issue.

As soon as it happens again I will do it.

Actually the problem was that the sample project didn't have any interface :)
After adding some knobs it shows the GUI as expexted. Sorry for the noise.

By the way, the interface editor seems a bit bugged. Sometime I cannot move or delete a widget. I have to close and reopen the project, create again the widget and then I can edit it....

@Lindon thanks, I will test with the develop branch. By the way the BasicSynth since to have received updates recently.

PS: I'm using my own build because I want to configure my local IPP to make the export of VST work. I guess there's a better way to configure IPP inside the buil.bat for the project...

EDIT: @Lindon anyway the master branch looks updated to the latest release

It looks like the ValueTree is not instantiated correcly.

The same happens with the Standalone version of BasicSynth

I've succesfully exported the BasicSynth Project as a VST on Windows. I have my BasicSynth.dll loaded in Reaper but only a placemarker (cross) is visible

I'm using HISE master branch self-compiled Release standalone with VS 2022 (and IPP)

@d-healey I was also going to ask the same question, a little differently: Is there any plan to implement this?
It would definetely be a huge feature, that would make HISE shine within the arena of audio development tools (I'm a Kontakt and UVI Falcon user).
