Jan 29, 2012 - Gemstone Technologies introduces BeBob's Sound Contraption Pro for iOS devices. You can MotionWarp sounds to make a cool & fun instrument, warping sounds in real-time just by moving your iDevice. Use SoundShaker to play air-guitar or air-drums, shake the maracas, tambourine, or even frogs. Combine effects including Sound Looper, Stutter Sound, & Echo Multiplier with the Warp Slider or MotionWarp to create a whacky soundboard or cool beat-box/drum machine. Share the fun with friends!
