iPhone Music Software: GyroSynth is a new $.99 music synthesizer for the iPhone 4, which takes full adventage of the gyroscope.

You can play and modulate the sound by moving your hand through the air, theremin style.

• 3 types of oscillator: vocal (formant synthesizer), sine wave and square (PWM modulation)
• Several control modes
• Delay effect
• Included musical scales allow you to effortlessly play in several styles
