Some compressors (e.g. Logic stock, and Scheps Omni Channel Comp.) offer the option to switch between different compressor types while maintaining the controls of attack / release / ratio. Let's use three common ones as example: VCA, FET and Optical (see attached screenshot). Quick simplistic summary of their behaviour (as far as I learned until now; please feel free to add/remove/correct): VCA = fast + transparent; FET = fast + colourful; OPTO = slow + transparent Now to my question: -> If attack + release are set at fixed values and I switch (let's say) from FET to OPTO, what exactly is happening internally? -> Does the knee change? Do attack + release change behind the scenes and the values on the GUI are not always 100% correct? What is going on? In another plugin, TDR Molotok, you can have an extremely short attack time and still have the transient coming through when a slower mode called Omega is activated. Same question here. I think it would help me set up my compressors better if I knew what was going on. Can anybody help? Thank you so much!! PS: If anybody owns the Scheps Omni Channel 2 and knows more about the 4 styles, including the SOFT style (beyond the too short manual description which was not sufficient for me), please enlighten me :) Again, thank you!
