Thank you so much for your time. It’s valuable to get an answer.

Steps to reproduce:

FX:

1FX - ReaGate by Reaper  
2FX - IPluginEffect (no sound)

But it’s strange to me that such large companies can’t fix this problem.

While searching the forum, I tried it and it helped me:

Thanks for the forum!
