Another collaboration with Versilian Studios, and our shared entry in the 2026 KVR Developer Challenge. Our 2021 collaboration Virtuosity Drums won the soundware category that year.

This is a quiet piano sample library with low noise, consistent playability, multiple mic positions and a few non-traditional controls named after Egyptian deities, except Horus, which is too heretical to be named after a deity, and is named after the Warmaster. Over 1200 samples adding up to 460 MB even with FLAC compression.

Versilian have also released a completely separate sample library of this same piano, recorded months later and across its full dynamic range.
