Pro tools. Problem with the second plugin instance


Just found strange behaviour of my plugin in protools when I add the second virtual instrument to the track.

For example:

  1. Create track.
  2. Add my plugin. The result: everything is ok.
  3. Add one more plugin (Doesn’t matter if it’s another instance of my plugin or any other virtual instrument). The result: no sound from my plugin. Animation is working. Process block is working. No crashes or freezes. I see correct level meter indication inside my plugin. But no sound.

If I drag and drop my plugin and put it AFTER the second plugin, my plugin starts working again.

So it works correctly if it has the last position on the track or when it’s the single plugin on the track.

Maybe you know what the reason?

Still has the problem.
Nobody knows the reason? Maybe any ideas what to check?
