Hotone Freqlux Pitch and Harmony Pedal

Freqlux is not just another pitch pedal — it’s a creative engine built for players who think harmonically. Featuring three fully independent pitch voices and deep real-time control, Freqlux transforms complex harmony ideas into a playable reality.

Whether you're crafting layered harmonies, detuned textures, evolving arpeggios, or dramatic gliding pitch transitions, Freqlux offers exceptional flexibility through its powerful tri-pitch architecture and expressive performance tools.

Three Voices. Unlimited Directions.

At the core of Freqlux are three completely independent pitch engines. Each voice can run a different mode, interval, and behaviour. Unlike traditional mono or standard poly pitch pedals, Freqlux lets you stack, blend, and sculpt three pitch ideas at once.

Each voice can be assigned to one of the following modes:

• Poly Mode - Flawless polyphonic pitch shifting that preserves chord structure and articulation. Big chords stay intact. Fast passages stay clean.
• Key Mode - Set a key and scale, and Freqlux generates musically intelligent harmonies that move with you. Classic harmony tones with modern precision.
• Detune Mode - Micro pitch offsets layered with your dry signal for massive chorus, stereo width, and thickness without losing clarity.
• Mod Mode - Bypass pitch shifting entirely and use an independent modulation engine. Vibrato and modulation effects add movement and depth to any voice.
• ARP Mode - Turn pitch shifting into motion. Combine poly pitch with Flux or Auto Flux to generate real-time arpeggios locked to your selected scale. A completely new way to play.

Fast. Precise. Built for Real Playing.

Freqlux delivers ultra-fast pitch tracking while preserving your dynamics and tone. In drop-tuning scenarios, pitch latency is reduced to an industry-leading 4 to 5 ms. Combined with transient-optimised processing, drop tuning feels tight, natural, and powerful. Low strings stay punchy. Pick attack stays intact. This is drop tuning done right.

A Sound Designer’s Playground

Freqlux gives you mix-level control over every voice, letting you shape harmony like a producer, not just a guitarist.

• Stereo Placement - Independent pan and level controls let you place each voice exactly where you want it in the stereo field. Your soundstage, your rules.
• Depth and Definition - Tone and Swell controls per voice allow precise shaping of brightness and attack behaviour. Build layered harmonies that breathe and evolve.
• Emotion Control - Each voice features its own FX processing so harmonies never feel static or mechanical. Add movement, texture, and life to every note.

FX That Give Pitch a Soul

Freqlux FX modules are designed specifically for pitch voices, not slapped on as an afterthought. Mod and Tremolo add expressive motion. Feedback transforms short harmonies into evolving soundscapes. Adjust feedback time and repeats per voice for advanced multi-pitch delay textures. Drive and Tone controls let you dial in anything from subtle grit to aggressive harmonic saturation.

Flux. Your Second Instrument.

Freqlux features two footswitch modes. Preset Mode for fast preset changes. Control Mode turns the Flux footswitch into a real-time pitch controller. In Control Mode, Flux becomes a playable pitch pedal. Customize attack, release, and pitch curves for smooth glides, dramatic drops, or rhythmic arpeggio triggers. Auto Flux takes it even further. It detects your playing dynamics and automatically triggers pitch slides or arpeggios with no foot control required. Stay locked into the performance. Let Freqlux handle the motion.
