GyroSynth is a gesture driven music synthesizer, which takes full adventage of the gyroscope. You can play and modulate the sound by moving your hand through the air - just like the legendary Theremin instrument. GyroSynth makes use of the gyroscope to measure true roll, pitch, and yaw and translates them to sound parameters like pitch, volume, modulation or filter cutoff. Thanks to phenomenal accuracy (2000 degrees), you can play melodies perfectly in tune. A finalist in 'Most Innovative App' category at the 2010 Best App Ever Awards (148apps). GyroSynth has been used in numerous live jams and performances (e.g., Mindex) FEATURES - Synthesizers: vocal (formant synthesizer), sine wave , square (PWM modulation), saw, granular sample player with recording function and R2D2 - experimental FM modulation - Effects: delay and boost - Several control modes - Included musical scales allow you to effortlessly play in several styles - Built-in recorder and player with overdub function "There isn’t too much more to say about GyroSynth other than wow!"
