Pro Tools 12.6 & the SSL Duende plug-ins do not play nice. After a few hours of trial & error, I got a workaround!
- I saved a session with a single Aux track with a single Kush Audio Transformer N insert.
- Open this session.
- Load any previous or create a new session with any SSL Duende plugs you feel necessary.
The Kush plugin seems to do the trick. I’m sure others might as well. This is working for my system without fail. Here is the simple “pre-Loader” session. Good luck. duende-pre-loader.zip
