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

Twisting real knobs on the 500 series Hedra is way more fun than a plug-in when I’m working on a studio vocal chain.

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.
