The button can be configured to adjust any function in a Symetrix DSP that is controllable. In addition, Symetrix DSPs can control the third-party devices included in the Toolbar of Symetrix ComposerTM software and other third-party devices via RS-232 (Radius and Edge), TCP or UDP. 

Buttons can be configured to be momentary, latching or as radio buttons. This allows them to do things like trigger presets, adjust volume levels, perform source selection, mute/unmute audio and change signal routing. There is a caveat regarding the radio buttons – radio buttons must be sequential.
