Meris Hedra Rhythmic Pitch Shifter Pedal

Hedra from Meris is a rhythmic pitch shifter with three pitch shifters and linked delay lines, making it great for complex rhythmic pitch shifting, harmonies, and polyrhythms. First, set the key and scale selection, which will set the notes available for the pitch shifting. The pitch shifting offers two octaves above and below the base note. The delay is a tap tempo delay with feedback and 520ms of delay, with the ability to slow that down by half. Each pitch shifter has a delay setting and can be offset from the master delay tempo with divisions of that clock speed. Four delay modes are available, including a long series delay, series delay with pitch shifting in the feedback loop, dual delay lines each with their own feedback in stereo, and dual delay with cross feedback for bouncing stereo delay. Microtune detunes each voice, capable of everything from a chorusing-type effect up to warbly pitch shifting with feedback path.

Hedra can be set to no correction, loose correction, or strict pitch correction that removes note bends and provides a stair stepping effect between notes. On the other side of things, glide can be added for a smooth sliding between notes. The expression pedal input provides control over every parameter. Set the expression pedal all the way down to the heel position and tune the settings to your liking. Then move the pedal all the way to the max toe position and make a new setting, and now the expression pedal blends between these two settings. MIDI integration allows the Hedra to be controlled with external MIDI controllers, DAWs, and more. This rhythmic pitch shifter moves past simple pitch correction and adds complex delay lines that can provide harmonically rich and rhythmically complex results.

The Bladerunner Synth (Yamaha CS-80) With Meris Mercury 7 & Hedra
Few synthesizers have achieved the legendary status of Yamaha’s CS-80, and it’s always a treat when one comes through our store. When it was released back in 1977, it was state of the art for its time in offering a generous number of presets (some fixed and some programmable), two synth layers per voice, and excellent performance features like polyphonic aftertouch and a flexible ribbon controller.

Among the most iconic uses of the CS-80 was in the score for the 1982 film Blade Runner, written by Greek composer Vangelis. Along with the synthesizer itself, the music of the film is renowned for its use of space and ambience supplied by lush reverbs and effects processors. Coincidentally, expert pedal and pro audio designers Meris have a Blade Runner inspired reverb pedal called Mercury 7 that aims to recreate these dramatic reverberant textures with ease. Pairing this pedal with the CS-80 was an obvious choice, and we also made use of their Hedra pitch shifter to add another layer of magic to some sounds.
Singing Into Pedals: Vocal Techniques for Effects w/ Katrina Cain!
In her recent visit to our studio, LA-based singer-songwriter Katrina Cain shared some valuable wisdom on using creative effects with the most naturally expressive musical instrument: the human voice. We frequently get questions from curious vocalists on how they can explore interesting pedals in combination with their voice, and in this video Katrina not only shows an example of an effective pedalboard setup, but also some important tips on modifying your technique and vocal delivery for achieving the best sonic results. From considering vibrato with harmonizers to using glottal or consonant attacks for defined pitch tracking, many of Katrina's tips are key to understanding how effects can be constructively applied to singing while remaining intelligible and clear.

Using a small curation of her favorite pedals, Katrina shows that you don’t need a ton of effects to prepare an engaging vocal performance. While it contains both a preamp and selection of effects itself, the Old Blood Noise Endeavors MAW also solves the critical issue of bringing the XLR-based microphone into the land of 1/4” pedals. From there, the Mercury 7 and Hedra from Meris respectively offer spacious reverb and ethereal harmonization and delays, and the Ditto Looper from TC Electronic lets Katrina gradually capture and layer multiple vocal lines over the course of a performance.
