What do you mean with “which PC does the plugin window not appear on”?
VSTConnect Performer is running on Windows 10, tried 4.0.40.180 and latest beta up to date. Interface is RME Fireface 800.
All plugins, tried about 60 different, including NI Komplete, VST3 and VST2. When I hit the “edit” button, no UI and no sound when triggering it via MIDI.
Will test the latest beta and let you know.
Thanks for the help!
