S.709 is a synthesizer that uses four multitouch points on the screen and the accelerometer to give a large amount of control over a sine wave output. It’s good for creating strange noises and sound design.
Orange – Volume and Pitch (radius control pitch range)
Pink – Ramp speed and note length
Blue – Delay Length and Pitch (hold down for delay)
Green – Delay Filter and Feedback
Accelerometer controls pitch and wave shape.
S.709 is available for $1.99
