MagneTheremin

Magnet based theremin - 将磁场转换为声音以创造独特的音乐

The MagneTheremin is a sensor-based music instrument which uses readings from the device's Magnetometer to modulate the frequency of an oscillator.

A more intense magnetic field will be translated into a higher audio frequency.

Hold a Magnet in your hand, and you've got yourself a real Theremin!

FEATURES

♬ You can play exact frequencies of tones in six different scales - Chromatic, Major, Minor, Blues, Pentatonic, and Makam Hijaz.

♬ Choose one of four different wave forms - Sine, Triangle, Square, Saw.

♬ Add per-recorded backing tracks in different styles and scales to enhance your jamming.

♬ Adjust the glissando - 1 / 18 / 65 / 120 / 450 ms.

♬ Adjust the tempo of the readings - 60, 120, 180, 240 bpm (e.g. 120bpm will send a reading every 500ms).

♬ Device won't go to sleep while the app is on, which is ideal for live performance.

♬ Mute button, Reset button.
