It features a "tracker" style sequencer, and a built-in synthesizer capable of a wide range sounds - including but not limited to basic subtractive synthesis, frequency modulation and sample playback. Sounds can be easily beefed up by using the effect chain.

Tunes can be easily exported as a single mixdown .WAV or separate tracks or you can simply use the playback library to use the klystrack files in your own games and other software.
