Some days ago I stumbled upon a YT video and it led me here:
Vaults - The Crow Hill Company
They feature a growing free instruments library, started with a piano and recently added strings.
Their description of this project is:
Vaults Beta is a free plug-in that marks the beginning of a never ending stream of free, original and inspiring sounds for you to keep forever.
I liked it and so have shared it with you 😃
