HARMONIES IN STEP

3-Voice Studio Pitch Shifter w/ Hard Tuning

A Stranger In Our World

Her Light Will Change Us

“We are the music makers, And we are the dreamers of dreams…” – Arthur O’Shaughnessy (1873)

Angelo Mazzocco

DSP Engineer/VP

Adding the Hedra to my home studio’s 500 series rack was the realization of a long awaited dream. The instant access to micro tuning, pitched delays, and rhythmic harmonies direct from my channel strip has made adding color while tracking effortless.

INNOCENCE IN SPIRIT

Powerful in Execution

Put Hedra 500 into your studio rack and re-voice your melody palette in real time. 3 voices, in rhythm, combine with your original voice to create angelic harmonies. Each voice can be delayed and fed back for classic studio fattening, detuning, or extreme warping. Explore pitch locked harmony, either smooth or hard stepped and use your voice as an instrument. Add sonic unease and texture by micro tuning each voice or with our original glide mode to slide between pitches.
