If you have soldering skills it is possible to connect one or two foot switches to a serial COM port
A switch between pins 4 (DTR) and 8 (CTS) can be used for hands free selection of the next song or metronome on/off control. A second switch between pins 4 (DTR) and 6 (DSR) can be used for hands free selection of the previous song or audio file playback.
Choose the COM port by selecting Foot Switch in the Options menu.
WARNING: Do not attempt this unless you are aware of the risks and are confident you have the necessary skills.
