Meris Hedra 3-Voice Rhythmic Pitch Shifter & Delay Pedal

An intricate stompbox for weaving dreamy harmonic textures and otherworldly polyrhythms!

Written by

Sam Beattie

Meris live at the fringes of the pedal world, seeking out bold new sounds that defy the laws of tone. Incorporating MIDI control, intricate algorithms and stunning studio-quality audio resolutions, they're true stompbox trailblazers. 

Introducing the Hedra, a 3-voice rhythmic pitch shifter. The rhythmic element allows you to craft pulsing riffs, dancing leads and otherworldly polyrhythms with your instrument. The complex pitch controls offer a harmonic deep-dive experience, with 3 layers and a vast number of interval combinations to play with. Combine the two, and you've discovered a rarity in the pedal world; something entirely new.

Here's what Meris say:

The Hedra is capable of adding 3 harmony voices to your instrument and with tap tempo synchronised delay available for each voice. It transcends the realms of standard pitch-shifting. In addition, pitch glide, micro tuning, 4 individual delay configurations, adjustable pitch correction and MIDI keyboard control all combine to offer a sonic experience like no other.

Keep it simple and just use Hedra as a standard chromatic pitch-shifter. Or pile on the intervals and slip into its dancing diatonic dreamscapes, via its 6 different scales and wealth of rhythmical subdivisions. Turn up the glide control and hold down tap for auto-swelling synthy portamento shifts - or bump up the pitch regeneration - and you’ll be floating away on clouds of shimmering sci-fi effects. Hook a MIDI Keyboard or a MIDI Sequencer up to Hedra and turn your source instrument into a mind-bending tapestry of harmonies and hard-tuned pitch glides.

Although it adds an entirely new dimension to the humble 6 (or more) string instrument, Hedra is not limited to just guitars. In fact, you can use the pedal on pretty much any instrument or line-level audio signal you want. Whether you choose to totally transform your beats on a drum machine, harmonise vocals or completely alter additional synths, loops or any other type of audio, Hedra’s advanced pitch-shifting palette is sure to transport you and your sound to entirely new sonic worlds.
