First of all congratulations for this fantastic tool. I think it may be the Serum killer.
I use Vital with Reason Suite and have noticed that while the sequencer plays the 4 tabs (Voice, Effects, Matrix, Advance) are not displayed.
To view them I have to stop the sequencer.
It even happens when I want to open Vital VST while the sequencer is running, the Vital screen is white.
I have to stop it for the screen to appear.
Some advice?
I’m a Mac user - iMac with High Sierra
Many thanks
