Sonora Cinematic, the developer of Poiesis Cello and the Magnetism series, has released Aria Libera, a free Kontakt instrument:
Aria Libera features the beautiful humming of singer Emma May Price processed through a granular modular synthesiser.
The result is an inspiring and effortless tool for adding beautiful vocal textures, atmospheres or pads to underscores. It's also excellent for experimental and glitchy sounds.
Users can assign Aria Libera to any MIDI controller and use the XY pad to expressively shape their sound. Move across the X axis to increase the granular effect and use the Y axis to diffuse the sound in space.
