Harmor Masterclass Module 6 - Filters

Harmor has a Dual filter in each part, that is 4 filters in total.

Harmor Filters vs Other Filters

From the perspective of the mixing engineer and the sound designer, Harmor has the best filter section among the generator plugins and effects. This is a Pretty Bold Statement, but I do have some facts to support this claim.

The main features that make the Harmor Filters best in class are

  1. The Filters in Harmor are linear phase, i.e. The phase of Sound does not change even at the extreme filer bands Drops. Normally you have to buy 2 plugins(Phase alignment tool and linear phase EQ) to do cover these functions and can still fail to get a perfect phase.

  2. Unlike other plugins and filters; Despite being a linear phase filter, Harmor does not introduce any latency in sound.

  3. The Filters in Harmor not only can be set to hard parallel and series, but you can also morph and even modulate the configuration of Filter 1 and Filter 2.

  4. You can Design your own filter and resonance shapes in Harmor, this opens up whole new possibilities in sound design.

  5. While Normal filters have specific bandwidth values(12,24,36dB/Oct) Harmor Filters can easily Morph among those numbers. So you can have a 15dB/Oct if you want or make the flat curve, what's more, amazing is that it doesn't affect the phase of sound at all.

  6. Resonance in Normal Filters moves along the cut-off frequency, In Harmor Resonance is independent of the cutoff frequency, you can send the resonance point anywhere in the frequency range, even outside the filtered area.

I can give you many more features that make Harmor Filters stand out, but I guess you already have an idea by now.

So What makes these filters do these amazing things, Why is Harmor able to do these tasks without breaking a sweat while other plugins can't?

The answer lies in the working principle of the Filter.

As I mentioned in the earlier modules, in Harmor, Harmonic Data is processed instead of Waveforms, and Filters are no exception, when you use the filter in Harmor, you are actually affecting the Harmonic Levels instead of Waveshape. And that is why you can perform more complex filter functions in Harmor.

Now that we have established the supremacy of Harmor Filter, let's talk about filter configuration in harmor.

Filter Configuration in Harmor

In harmor you can morph between Parallel and Series Filter Configurations.

The image below Indicates the Signal Flow with the Configuration.

Harmor Filter Parellel
Filter 2 is Active, Filter 1 is Inactive.
Filter 1 and Filter 2 are active and parallel
Filter 1 and Filter 2 are active and parallel
Filter 1 is active, Filter 2 is Inactive
Filter 1 is active, Filter 2 is Inactive
Filter 2 is processing Signal and Sending to Filter 1.
Filter 1 is Processing Signal and Sending to Filter 2
Filter 1 is Processing Signal and Sending to Filter 2

Filter Options in Harmor

Let's talk about various knobs and their functions in the Harmor...

Filter Cut Off

The most important and essential Function, Filter cut offsets the cutout frequency. There are two modes in Harmor to set the filter resonance peak

  1. Octave

  2. Hz

Octave(Oct) filters the frequency in Octaves.

Hz is your traditional frequency-centric filter.

Filter Modes in Harmor

Low Pass - Filters frequencies above the cutoff.

High Pass - Filters Frequencies below the cutoff.

Band Pass - Filters frequencies around the cutoff on either side.

Band Stop - Filter at and around the cutoff

Phaser - A combination of Bandstop filters, works like a comb.

Custom Shape - Creates custom filter shapes

The Additional Filter modes Crude, Hill, Fin, Classic, Lag, Snake, Leaky etc are different filter curves.


The Width or Bandwidth knob decides the length of the Filter Curve, in a traditional filter, it is indicated by dB/Octave.

kb Track(Keyboard Tracking)

kb track function sets the keyboard tracking, i.e. the filter cutoff changes according to the pitch of the sound. It basically adds an offset to the original value. The value of kb track can be set to negative or positive.


The envelope sets the amount and polarity of modulation for the filter. You can set it from -100 to +100.

Adaptive Envelope

An advanced feature that sets the bandwidth according to pitch, allows us to create a balanced filter throughout by making the time of the envelope uniform.


Filter Resonance can boost or cut(Only in the case of Harmor) the frequencies around the cutoff. Harmor has far advance resonance settings compared to traditional plugins. That is why it defies the normal work functions of Filter.

Let's Discuss some Options of Filter Resonance in Harmor

Resonance Types

Classic - A traditional Narrow Resonance shape found in most Analog filters.

Cuberdon, Pedestal, Sedge hat, Wide bump, Double cone - Filter Shapes just as their names(Pretty fun if you as me)

Well - Creates a Drop-in Frequency.

Wormhole - Same as well but boost frequencies around the well.

Low Pass - A low pass filter, creates a dip after the resonance, gives an analog character to the sound.

Custom Shape - Create your own resonance shapes using this function.

Noise - Special Shape that activates random harmonics, good for cinematic and chill sounds.


Resonance Width makes the resonance range shape or narrow. Adaptive modes change the width according to the frequency.

Ofc - The resonance frequency offset. Use it to shift the resonance peak 2 octaves above or below the actual resonance point.


Self Oscillation, A special feature that creates a single self oscillator, this oscillation is not bound by the cut-off. You can take it beyond the cut-off as well.

It can add a nice character when mixed with the first few harmonics.


This is it for this module, I hope now you know everything about filters in fl studio harmor, shapes, resonance etc.

In the next video, we will talk about the Prism section in Harmor.
