Miniature music machine.

Grid Music is a 2-dimensional MIDI step sequencer for iPad and iPhone. It can be used to compose classic 16-step patterns, but can also create loops, random branches, and polyrhythm. Its 5×5 grid allows for countless arrangements of melody and timbre while keeping the entire composition visible and easy to understand. Pitch and rhythm can be directly manipulated by touch, and the structure of a pattern can be altered in just a few taps.
