FL Studio Harmless Synth Tutorial

Tutorial on the Harmless synthesizer in FL Studio, part of the basics series showing how to create professional sounds from the default patch.

• Lush professional pads • Professional plucks • Professional bass sounds

The Harmless interface is intense and overwhelming at first, with all controls visible on one screen with no extra pages or menus.

A three-step process to simplify the interface by sectioning off controls and focusing only on the ones you need.

Harmless synthesizer loaded in FL Studio with an EQ used as a visualizer to see frequency changes discussed in the video.

The default patch has a filtered sound that needs the frequency dial in the middle turned all the way up to open it up and get a nice open sound.

Every single control is on the interface with no hidden pages or menus, making it overwhelming but providing direct access to all parameters.

• Sound generation • Sound shaping • Voice configuration

Choose your base waveform starting with saw, which is versatile and recommended for beginners. You can also load custom single-cycle waveforms.

• Attack: controls how long it takes sound to reach maximum volume • Decay: controls how quickly sound drops after the peak • Release: controls how sound fades when note ends

Short attack and decay create pluck bass sounds, while long attack and decay create spacious pad sounds.

Add multiple voices (5-6 recommended) to create wide, spacious sounds. Adjust pan width, style (blurred recommended), and pitch variation for additional texture.

A special filter that smoothly and quickly removes the high end of the sound, useful for creating chunky pluck sounds.

• Classic: standard unison • Blurred: softer, mushier sound • Uniform: different voice options

Adjust pan width to spread voices narrowly for focused sound or widely for spacious stereo effect.

Modify pitch, phase, and variation of different voices for more advanced sound shaping.

An equalizer that tracks the notes you're playing, allowing you to remove specific harmonics (first, second, third, etc.) rather than just cutting frequencies.

Remove harmonics 1-12 with precision control, giving much more tonal control than a standard EQ and tracking with the notes you play.

Induce sub frequencies and harmonics below your played note, and use low harmonic protection to preserve low end integrity even when filtering.

These tools provide precise control over tone and texture beyond what standard filtering can achieve.

• Low-pass filter: cuts high frequencies, allows lows through • High-pass filter: cuts low frequencies, allows highs through

Adjust resonance and frequency cutoff. Low harmonic protection preserves lowest note in chord from filtering.

Attack and decay settings make the filter swell up and down, creating wobble and pluck effects with quick attack and decay times.

Filter settings are standard across synthesizers but arranged differently in Harmless, using curve shapes instead of draggable graphs.

• Phasers: phase the sound for movement • Delay: classic, ping pong, or stereo options • Reverb: various room types and sizes • Compression: increases volume as you increase mix

Effects sound clean and professional. Many users rely on Harmless built-in effects rather than loading external effect plugins.

Unlike most synthesizers where effects are hidden behind menus, all effects are visible upfront in Harmless.

A touch of reverb on bass can make it sound more spacious, even though traditional wisdom suggests avoiding reverb on bass sounds.

Slightly detunes or tunes up various harmonics, creating metallic sounds useful for percussion synthesis or interesting tonal features in low-end sounds.

Low frequency oscillator that acts as a predetermined automation clip, controlling various parameters up and down at a selected speed.

• Sine wave: smooth up and down • Pulse: turns on and off with no ramp

Almost every control has an LFO option beside it. Controlling filter frequency with LFO creates rhythmic wobble and movement effects.

Load default patch and select the desired octave range for the bass sound.

Pull down the decay to create a short pluck effect, giving the bass a percussive attack and quick tail.

• Use pluck feature for natural high-end click • Use EQ to remove unwanted clicks in high frequencies • Add subtle reverb for spaciousness • Increase unison for modern, wide sound

Add distortion from compression section. Consider using EQ later to ensure mono, solid low end.

Turn attack up to avoid immediate sound start. Set long release and decay so sound fades away gently instead of cutting off.

Add reverb with a big cathedral setting to create spacious, evolving pad texture.

Maximize unison to 9 voices and enable high quality mode for smoother, richer pad sound.

Use harmonic mask feature to create metallic tones and more textured variations of the pad sound.

• Generate and shape the sound • Filter the sound • Add effects

Breaking down the interface into sections makes Harmless much less overwhelming. Understanding where sound is generated, how to shape it, and where effects go demystifies the synthesizer.

The channel offers a comprehensive sound design series covering beginner and advanced techniques, as well as recreations of classic and modern synth sounds.

The techniques taught for Harmless apply to other synthesizers like Serum, Helm, and Massive, making them valuable for any synthesizer you use.
