iThereal is a multi-touch trackpad controlled virtual Theremin. Zero Crossing says that iThereal can be used to create music with a classic Theremin sound while staying true to a Theremin feel.

A spokesperson said, "A Theremin often has a loop antenna on the left that manipulates the volume and an upright antenna on the right which controls the pitch of a note. The proximity of the musicians hands effect the quality of the sound the Theremin emits. iThereal mimics these controls with touches on a trackpad."

Features:

• Use Pitch Lock to ensure notes are chromatically tuned.
• Add effects to your sound like Reverb, Distortion, and Vibrato.
• Use with midi hosting applications like GarageBand to incorporate an iThereal track into a musical composition.
• Fully customizable user interface gives each musician a unique playing experience.
