Quick start

The installer will copy the FabFilter Pro-C plug-in into the common RTAS and VST plug-in folders (Windows) or the /Library/Audio/Plug-Ins/Components, VST, or Pro Tools plug-ins folder (OS X) on your computer.

In most cases, your host will then recognize the plugin automatically. However, if the instructions below do not work, see Manual installation instead.

Cubase SX
Choose an empty insert slot and select FabFilter Pro-C from the pop-up menu. To use Pro-C MIDI Learn feature, create a new MIDI track and set its output to the FabFilter Pro-C instance you have just created.
Logic Audio
Choose an empty insert slot on one of your audio tracks, instrument tracks or buses and select FabFilter Pro-C from the pop-up menu. You will find FabFilter Pro-C in the Stereo > VST (Windows) or Stereo > Audio Units (OS X) section. A mono version is also available from the Mono menu.
Pro Tools
Choose an empty insert slot on one of your audio tracks, instrument tracks or buses and select FabFilter Pro-C from the pop-up menu in the Dynamics section. Note that there are both mono and stereo versions of Pro-C available.

To begin, make sure attack and release are both zero. Put the ratio in a gentle 4:1 setting and bring down the threshold to make compression audible. Play with those parameters until you have the desired effect. Have fun!
