Meris Hedra – 3 Voice Rhythmic Pitch Shifter & Delay

Meris Hedra

Meris Hedra is a 3-Voice Rhythmic Pitch Shifter

Every action has a reaction.

A single stone thrown can create riveting ripple effects. A humble key turn can unlock a flurry of otherwise before unseen and unheard events.

This is the magic Hedra bestows upon you and your instrument, seeing you unearth new harmonic sonic chain reactions with every single note played.

What is the Meris Hedra?

The Meris Hedra is a 3-voice rhythmic pitch shifter capable of adding 3 harmony voices to your instrument.

And with Tap tempo synchronised delay available for each voice, this beauty far 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 in making Hedra an instrument and sonic experience like no other.

You can keep it simple and just use Hedra as a standard chromatic pitch-shifter.

Or you can begin to pile on the intervals and slip into its dancing diatonic dreamscapes, via its 6 different scales and wealth of rhythmical subdivisions.

Now 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 six-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.
