I'm having repeatedly this problem when I load Massive (not Massive X) into Komplete Kontrol (3.3.4).
I can load the instrument and tweak it correctly, but once I close the instance of the plugin (to tweak other tracks) and come back, the interface is totally black and I can't see the controls anymore.
This just happens with this instrument (Massive), not any else. It happens to me in diferent computers and diferent versions of macOS and Logic Pro.
That's what i'm using right now:
Komplete Kontrol 3.3.4
Massive 1.7.0
Logic Pro 10.7.9
MacOS Sequoia 15.0
Has anyone experienced this??
