The De:Esser is exactly what it says, and what you think it is.
Limitations of the freebie:
- No Multi-mono support
- No Session-restore functionality (you have to re-set it everytime you open a session)
- No Save-and-restore functionality (can’t save presets)
- No Automation
The “demo” free version is completely usable as is (just a little annoying) and exactly the same as the paid version, minus those limitations. But at the price of only $89, the full version really is worth it.
