Fruity Love Philter

Fruity Love Philter is the most powerful filter plugin in FL Studio. Love Philter consists of eight identical filter units, each able to be run in parallel OR used in series by sending a filter unit to the next one in the chain. Love Philter can create complex delay, gating and filtering effects. Related, simpler, filter plugins are Fruity Filter and Fruity Free Filter.

NOTE: Love philter will steal MIDI input focus as it can use MIDI notes to switch the active pattern envelope.


Banks 1 to 8

Top-left are the Bank tabs and Enable Bank switches, above the tabs. Each filter bank consists of a series of processes that are described below (from left to right). The output from each bank can be sent to the plugin outputs and/or the next bank in the series.


The Input Section allows you to set the volume of the input signal.


The Filter Section determines the filter type and cut-offs used. The controls visible will depend on the filter type selected.

WS (WaveShaper)

A WaveShaper is a wave distortion effect which re-maps input amplitude (horizontal axis) to output amplitude (vertical axis) values using a flexible spline-based graph. It follows the same principles as shown in this video tutorial for Fruity Waveshaper.


In the Output Section each filter can pass its output to the following bank or to the main outputs.


Associated with each bank are a number of articulators/envelopes. There are two rows of tabs, the top row is used to select the articulator/modulator target and the bottom row the articulator modulation source. In other words, for each target in the top row there are a range of modulation sources in the bottom row that automate changes to those targets.

Articulators / Modulators

Modulation target types include:

Articulator parts

For each of the articulators above you can decide how each of the following modulator sources influence that parameter. The modulator can be a pattern (10 user definable pattern slots are available), LFO, Mod X/Y or the envelope of an input sound (IEF).

Common Envelopes Controls


This section allows X-Y modulation.


This section allows you to set up the Input Envelope Follower. The IEF acts as a modulation source and is based on the amplitude of the input waveform.

Understanding the IEF - Think of the IEF window as a dB/peak meter rotated on its side, increasing in volume from left to right (this is indicated by the increasing vertical ticks along the bottom of the IEF window). As the volume peaks of the input signal move across the window (there is no visual feedback, by the way), the IEF returns modulation values so that envelopes above the mid-line of the graph area are positive and envelopes below the mid-line are a negative.

The ief output values act on the currently selected 'Editor Target' tabs in the row above the modulation source tabs (the row the IEF tab is on). In this way there is a unique IEF envelope for each modulation target tab in the row above. Use the 'Env Amount' knob to define the maximum and minimum modulation values passed to the target controls. Finally, pay careful attention to the Attack (ATT) and Release (REL) knobs to the right side of the plugin (this section) in order to achieve the correct modulation effect. These controls act to control the peak dynamics (hold and fade) and determine how quickly the output peak is reached and held after the input peak has passed.

Three slider controls are located above the IEF section:
