The stk-demo program demonstrates several of the algorithms that are built into the Sound Synthesis Toolkit (STK). The stk-demo is a command line program, but it has a GUI frontend called STKDemo. Use STKDemo if you want to try out the different synthesis algorithms implemented in STK.
The stk-demo program can be used to build your own synthesizer/sequencer combination. The program is listening to SKINI commands on stdin.
Instrument can be one of the following:
Clarinet, BlowHole, Saxofony, Flute, Brass, BlowBotl, Bowed, Plucked, StifKarp, Sitar, Mandolin, Rhodey, Wurley, TubeBell, HevyMetl, PercFlut, BeeThree, FMVoices, VoicForm, Moog, Simple, Drummer, BandedWG, Shakers, ModalBar, Mesh2D, Resonate, Whistle
Simultaneous multiple output types are supported. Likewise, simultaneous control input types are supported. SKINI formatted scorefiles can be piped or redirected to stk-demo, though realtime control flags should be omitted when doing so. If the optional <file names> are not specified, default names will be indicated. Each flag must include its own '-' sign.
