Organic Instruments has released a new free virtual instrument called Ukulele, saying:

Features:

• Three expressive articulations: Ukulele was performed in a trio of distinctive styles, including plucked, over-plucked & muted playing techniques.
• Designed for Elemental Player, it includes built-in controls for reverb, dynamics, and ADSR envelopes.

Ukulele is available for free from the Organic Instruments website.
