Meris Hedra 3-voice Rhythmic Pitch Shifter Pedal

A next-generation harmonizer designed as an instrument

The Meris Hedra doesn't just "shift" a note up or down: it approaches pitch shifting as a complete rhythmic and harmonic material. Thanks to its 3 harmony voices and the ability to apply a synchronized temporal offset to each, Hedra goes beyond traditional harmonizer uses to enter instant composition territories: ghost arpeggios, counter-melodies, moving chords, and pitch effects that breathe with the tempo.

In the Meris spirit, everything is designed to encourage exploration: you can stay in familiar territory (simple chromatic pitch) or switch to diatonic landscapes, scale-driven harmonies, and sequencer-like note trajectories. Hedra then becomes a true "instrument within the instrument," capable of transforming a single line into a tapestry of tuned voices and interwoven rhythms.

Who is it for, for which styles, and in what contexts?

Hedra is aimed at curious guitarists and bassists, sound design enthusiasts, as well as keyboardists and producers who want to add movement to a mono or stereo source. Its behavior can remain musical and controlled to enrich a riff, or deliberately become unstable and spectacular for sci-fi effects, pitch dives, or synthetic choirs.

Regarding styles, it excels in ambient, post-rock, electronic, modern pop, math/experimental, but also serves rock and blues well if used to thicken a part (thirds, fifths, octaves) with a balanced mix. In the studio, it opens possibilities for double-tracking and instant harmonic arrangements. Live, its stereo output, presets, and MIDI control make it a formidable pedal for clean transitions and progressive build-ups.

Features and controls: from precision to extravagance

The heart of Hedra is its three independent voices: each has dedicated pitch and timing controls, allowing you to build chords, canons, or offset patterns that respond to each other. The Tap Tempo makes delays playable as a rhythmic element, and the subdivisions allow aligning repeats to the groove without struggling with the tempo.

To keep a musical output, Hedra offers chromatic or scale-driven harmony, with several scale types selectable via the ALT function. Add to that adjustable pitch correction (to lock intonation or allow micro-variations), and you get a pedal equally relevant for "clean" arrangements and experimental textures.

Want movement? The Glide mode lets you slide between pitches at a chosen speed, with the option for a smooth or more abrupt sweep for dramatic effects. The Micro Tune ranges from slight chorus-like detuning (stereo widening, studio thickening) to more extreme deformations. To push textures even further, Hedra includes options like half-speed and auto swell, perfect for pads and "violin-like" swells without attack.

Finally, Hedra is designed for modern setups: control via expression pedal over multiple parameters simultaneously, presets via an external 4-preset switch or MIDI, and MIDI over TRS through the EXP jack to control automation, preset changes, and synchronization. All with a premium analog signal path and high-quality conversion to maintain responsive touch and natural dynamics.

Sound

The Meris Hedra stands out with a signature that is both precise and organic: voices remain clear even when stacking multiple intervals, and the pedal responds finely to playing nuances. In subtle settings, it thickens a part like an "intelligent" doubling, with a sense of width and depth. In more adventurous settings (glide, advanced micro tuning, feedback, and delay routings), it becomes a texture generator: synthetic choirs, weightless harmonies, rhythmic cascades, and futuristic sparkles.

Thanks to digitally controlled analog mixing, you can precisely dose the effect integration: just enough to color a clean sound, or prominently to make Hedra the centerpiece of your pedalboard. On guitar or synth/line, it retains a hi-fi character, ideal for modern sounds and detailed productions.
