Question:
If mix buss contributions are set to pre-dyn, is this before or after the HPF (High Pass Filter)?
If pre-dyn (pre fader) is used for mix contributions, is that before or after the HPF?
Answer:
It is post HPF.
Setting mix buss contributions to pre-dyn does make the send pre-fader and pre any type of dynamics (eq, comp, gate). But this will always send post HPF.
There is no way to send pre HPF.
