VoxCarina app for iPhone and iPad

VoxCarina is a music instrument that is half an Ocarina, half a Talk Box.

You have to put your mouth next to the iPhone/iPad speaker so that you can shape the sound using your vocal tract.

You dont have to blow into the mic to generate sound (actually you cant do this, because you should be using your mouth to shape the sound), the sound is just created by pressing any of the four buttons.

You can customize the colors, turn on/off the reverb, turn on/off the glissando between notes, and the accelerometer to modify the sound when you tilt your device.

Its quite Alright.
