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

Powerful in Execution
Place the Hedra 500 in your studio rack and readjust your melodic palette in real time. Three rhythmic voices combine with the original voice to create an angelic harmony. Each voice can be delayed and fed back for classic studio fattening, detuning, or extreme warping . Discover soft or hard pitch-bound harmonies and use your voice as an instrument. Add sonic unease and texture by micro-tuning each voice or sliding between pitches with a Meris original glide mode.
