Solved. I should have installed VST2 instead of VST3. Now it works :)

If you have a minute to look at my problem below. Mille Grazie :)

Unfortunately I also have a problem with crashes. https://www.reddit.com/r/ableton/comments/g5u757/tyrell_n6_crashing_my_projects/ When I want to open a Live-Set where I use Tyrell my Ableton 10 Live Lite (using a VST3 under Windows 10) just crashes. If my live-set does not use Tyrell I have no problem. I wanted to use the workaround…
