XPressor for now@e-phonic: That means you have to port the plugins to VST3?
What are your priorities?
XPressor, Drumatic 4 and Retro Delay would be cool.
Seems to be hard to pinpoint the issue.
So far,
I've tested on 2 MacBook Airs, both run fine in Reaper, Studio One, BitWig, Element.
Let someone test on MacBook Pro, runs fine in Reaper, no UI in Studio One.
I've got a MacBook Air and all works fine, so it's impossible for me to debug the non-working scenario.
I'm now updating VSTGUI to the latest version.
