Linked plugin inserts

Why do some plugins work when linking inserts and others don’t?
The Steinberg plugins usually work while 3rd parties fail.
Is there anything that can be done to enforce proper parameter linking? I would be super useful to have this with 3rd parties as well.

Hi,

I’m not sure about this. Maybe only VST3 plug-ins support linking…?

It’s not VST3 related.

I only find proper plugin linking by suspending linking, add the plugin on one channel, Alt/drag it on the others, then take off the suspend linking and resume as normal.
