Meris
Hedra 3-Voice Rhythmic Pitch Shifter
Best creative tool for musicians crafting complex, evolving harmonic soundscapes.
The Meris Hedra is a sophisticated 3-voice rhythmic pitch shifter designed for both pedalboard integration and studio use. It offers deep control over pitch, rhythm, and delay feedback, allowing for the creation of complex harmonies and evolving soundscapes. The Hedra combines your original signal with three distinct pitch-shifted voices, capable of generating angelic harmonies. Explore creative possibilities with pitch corrective locking, smooth or hard-stepped glide modes, and micro-tuning for subtle detuning or extreme warping effects. It features four intricate delay configurations with unique feedback routing for versatile sonic textures.

What customers say
The Hedra earns high praise for its truly innovative design, delivering complex rhythmic pitch shifting unlike anything else available. Users consistently highlight the inspiring, lush quality of the three voice harmonies. While the depth of functionality is a major selling point, the initial ease of use presents a learning curve. Consumers agree that mastering the secondary functions requires dedication, but the resulting sonic textures and creative potential overwhelmingly justify the investment and effort. This pedal is seen as a powerful tool for serious sound designers.
Know before you buy
Yes. The pedal features switchable input and output headroom, allowing you to toggle between instrument-level for guitars and line-level for synths or studio gear.
Absolutely. It supports both MIDI for advanced synchronization and an expression pedal input, which lets you control various parameters in real-time for dynamic sound manipulation.
The Hedra includes selectable scale types that allow you to lock your pitch-shifted voices to specific musical keys, ensuring your harmonies remain musically consistent.
The glide mode determines how the pitch transitions between notes. You can choose between a hard-stepped mode for distinct, rhythmic intervals or a smooth mode for fluid, portamento-style pitch slides.
While the Hedra is primarily a rhythmic pitch shifter, its four unique delay configurations and feedback routing allow it to function as a highly creative delay unit, even if you set the pitch intervals to unison.
The Hedra requires a standard 9V DC power supply and has a current draw of less than 150 mA, making it compatible with most standard pedalboard power bricks.
