App Description

Spinstrument is a revolutionary "twist" of the classic piano keyboard. It incorporates phone movement and compass direction into a revolutionary way of playing music on your phone. Why limit music creation on your phone to the dimensions of the screen? Spinstrument provides the perfect way for you to play the piano, guitar, drums, and many other instruments in a whole new fashion. Includes: -Sampler: The sampler is similar to the keyboard instrument, but it allows you to create your own sounds. Simply record a sound through the phone's microphone, and voila - your new instrument is created. -Keyboard: The keyboard is a "spin-off" of the classic electronic piano. It allows you to choose your sound from a pre-loaded library and play it to your heart's content. -Drums: The drum instrument brings you the fullest experience of drumming on the App Store. Instead of tapping the screen, you can flick your phone to drop a beat. The drum instrument transforms your phone into a drumstick and the world around you to a drumset. Have fun. -Chords: The chord instrument allows you to play multiple notes of a chord at the same time. Visual strings on the app allow you to strum a chord or play arpeggios.
