FabFilter Timeless 2 offers the possibility of feeding an external signal
to its side chain, so that you can make it trigger on a different signal than
the audio it is actually processing.
Feeding a signal to a plug-in's side-chain inputs works slightly different in
various hosts. This topic describes the procedure for some of the most popular
hosts around: Cubase, Logic Pro,
Ableton Live and Pro Tools.
To explain how it works, we use a scenario with two tracks. The first one
contains the audio that we want to process with Timeless 2, which we'll call
the main track from now. The second track contains the audio that we
want to route to Timeless 2's external side-chain input and use as trigger
signal. We'll call this track the side chain track.
After setting up everything according to the instructions below for your host,
you can check whether everything is routed correctly: play the audio and
enable FabFilter Timeless 2's Audition button to listen to the side-chain
signal. Afterwards, disable the Audition mode again. Any
envelope generators or
envelope followers that are set to trigger on
the external side chain, will now respond to the side chain signal.
Open Cubase and create a new empty project.
Add two audio tracks that we'll use as main track and side chain track.
Add audio files on both the main track and the side chain track. You can simply drag audio files from a Finder/Explorer window onto a track.
Open the Mixer. In the main track, click on an empty insert slot and select the VST 3 version of FabFilter Timeless 2 in the Delay menu (note the VST 3 icon which looks like ///).
In the right top corner of the plug-in interface header, in the 'Side Chain' menu, choose the side chain track. Now, the signal from the side chain track is sent to FabFilter Timeless 2's external side-chain input.
Open Ableton Live and start with an empty arrangement. We'll use Track 1 as the side chain track and Track 2 as the main track.
From the folder menu's on at the left top of Ableton Live's interface, drag different audio clips to the first empty slots of Track 1 and Track 2.
From the VST (or Audio Units) plug-in menu, also at the left top of Ableton Live's interface, drag FabFilter Timeless 2 onto Track 2, the main track.
In Track 1 (the side chain track) in the 'Audio To' menu select 'Track 2' instead of the default 'Master'. Now, an extra menu appears right below: choose 'FF Timeless 2 3/4' instead of the default 'Track In' to route the track's signal to FabFilter Timeless 2's external side chain inputs.
Note: In the scenario above, you won't hear Track 1 (the side-chain signal) anymore, since its audio is only routed to Timeless 2's side-chain inputs. To avoid this, use one additional track (e.g. Track 3), choose 'Track 1' from its 'Audio From' dropdown menu, and in the 'Audio To' menu select 'Track 2' instead of the default 'Master'. Now, from the extra menu below choose 'FF Timeless 2 3/4'. Of course, you can now leave Track 1's 'Audio To' setting to the original 'Master' so you will still hear the signal.
Open Pro Tools and start a new empty session.
Create two audio tracks that we'll use as main track and side chain track. Add audio files to both track.
Open the Mix window to display the tracks with their Insert slots and Sends slots.
In the first 'Sends' slot of the side chain track, choose 'Bus 1'. The track view for Bus 1 will open: set its level slider to 0.0 dB so the bus actually produces audio!
In the first 'Inserts' slot of the main track, choose Delay > FabFilter Timeless 2.
Now, in the 'Key Input' menu of the plug-in interface (just above the FabFilter logo), choose bus > Bus 1 instead of the default 'no key input'. Now, the audio from the side chain track is routed to Timeless 2's external side chain input via Bus 1.
