Here is a first test release of VSTPlugin v0.6:
NOTE: previous versions would hide certain (non-automatable) parameters in VST3 plugins. This has been fixed, but as a consequence parameter indexes might have changed. VSTPlugin prints a warning for every plugin that is affected by this change!
One notable feature is that \vst_set now supports parameter indexes which allows for more flexible pattern composition.
Please test and report any issues at Issues · Pure Data libraries / vstplugin · GitLab.
Have fun!
