There’s lots of ways to achieve that sidechain compression style pumping in FL Studio. One of the fastest ways is to use the volume envelope pattern in Fruity Love Philter and in this short tutorial I will show you how.
First you need to route the sound you want to ‘pump’ into a Mixer track and drop a Fruity Love Philter into that Mixer track’s effect slot and reset it’s settings by loading the Default preset.
Now, in the filter unit 1 (you should be there by default), under the Filter section, disable filter by clicking the OFF switch (we don’t need any filter effects in this example).
Next, above the editor grid, click the VOL to set the Editor target as volume and underneath it, PAT to set the Articulator part as pattern envelope. Under the editor grid, enable the envelope by checking the enable box. Also, make sure that the Tempo-based time is enabled to make the envelope sync with your project tempo (check the TEMPO box). And lastly, enable the Snap to grid by checking the SNAP box.
And now, draw a following envelope:
So what does this do? This kind of volume envelope will make the volume of the signal quickly rise from silence to a full level over a time of one beat thus creating a pumping effect (one beat is 1/4 of bar – note that in the Love Philter editor grid, four of those dim vertical lines equals a one beat).
And finally, set the first envelope point as Loop start point (to make the envelope loop) by right clicking it and choosing ‘Loop start’ from the menu:
Edit the envelope point positions, levels and their tension levels to make the pumping sound the way you want (listen it with your kick drum to make it sit well to the rhythm).
Remember that you can also save the settings as a preset and then re-load it quickly anytime you need it from the Love Philter preset menu.
That’s about it. Watch the video version below and download the preset:
