I'm using the VST2 plugin but I also has some strange issues.
For example, the control boutons (play, record etc) start to play note instead of acting like they should.
And if I got Abbey Road loaded on track 2 and Scarbee bass on track 1, when I focus back to track 1, the lightguides remain the Abbey road ones and on screen Abbey Road plugin stay and not the scarbee.
Don't know if I explain myself clearly.
Cheers
@Benoit Peeters I created this thread from your comment, the thread was specific to VST3.
What is your operating system ? What version of Ableton are you using ? What kind of keyboard are you using ? Have you installed any remote scripts for Komplete Kontrol in Ableton ? If you are using a S Series MK2 keyboard or M32, A series, no scripts are needed, if you installed them, they can create conflicts. If you did, the easiest way is to reinstall Ableton.
