Sound Dust Cloud Cello
Cloud Cello is the big brother (or sister, if you like) of the Cloud Viola. She's a deeply multisampled hybrid Kontakt sample library created from a ordinary 17th century classical stringed instrument, but played and recorded in an extra-ordinary way.
Cloud Cello opens up new orchestral-ish, cinematic tones and textures that sound both familiar and alien....in a good way.
There are also 38 free Cloud Cello patches for Spectrasonics Omnisphere 2 included with the Kontakt version.
