Developer FingerTaps has introduced MidAir – an app that turns your iPhone or iPad camera into a gestural MIDI controller.

MidAir uses CoreMidi technology to interface with your Mac or PC to control your audio programs. GarageBand, Logic, Live and any program designed for MIDI input should work with MidAir.

MidAir is $.99 in the App Store. If you’ve tried MidAir, leave a comment with your impressions of it!

Note: A front-facing camera is required. MidAir is optimized for the iPhone 4S and iPad 2. Improved detection for the iPhone 4 coming soon.
