# STKDemo(1)

Sound Synthesis Toolkit demo application

Part of [stk-demo(1)](/stk-demo/1.md).

## NAME

stk-demo - Sound Synthesis Toolkit demo application

## SYNOPSIS

**stk-demo** Instrument \[*options*\]\
 **STKDemo**

## DESCRIPTION

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.
