Xx is a MIDI sequencer and composition environment that is built to work hand-in-hand with MetaSynth. One of the more unique features of Xx is its ability to convert any picture (PICT file) to MIDI data, allowing you to "paint with sound." In addition, Xx uses artificial intelligence (i.e. patterning, randomization, counterpoint, chordal creation, mutation, and evolve) to enhance your compositions or generate a variety of arrangements and theme ideas that Xx derives from earlier compositions.
