Rassel – Pocket Shaker transforms your iPhone to a shaken percussion instrument. Just pick up the device and shake it. This initial version comes with four different instruments: Egg, Shaker, Tambourine and Bells. Just swipe the screen to change between them. Unlike similar apps, Rassel is based on a unique audio rendering engine that accounts for continuous velocity changes based on how the sampled instruments are agitated. The device’s gyroscope is directly mapped to this velocity which makes any movement sound the way a real instrument would. We’ve tried to fine-tune the app to be as lifelike as possible, both in sound and handling response. We think we got pretty close. Features: - Instruments: Egg, Shaker, Tambourine and Bells Choose between loose, normal or tight setting - There is also a loudness boost option
