Theremini for iPhone, iPod Touch, iPad (Home
page)
The control of pitch and volume of tones is basic to making music and the Theremin was an early electronic instrument that enabled this by hand gesture. Theremini is a modern version where tilting gestures are used. Challenges are provided with a number of levels of difficulty and high scores are saved. Theremini can also be used to explore the human hearing range and as a test oscillator. |

Vibrato is also available and the pitch and volume ranges can be changed over the full human hearing range. Theremini Lite can also be used to explore the human hearing range and as a test oscillator. |

Sixteen harmonic sliders are available for hand-editing along with tremolo and vibrato. In addition, there are a number of preset waveshapes that can be called up using selector buttons. |
