Changing the Sound Files
Provided your computer has an audio-interface capable of playing back audio, sounds will optionally play while actuating relays, switches, valves and while activating the buzzer. You may use your own sound files instead of the preset ones by replacing the sound files in the snd-folder. The sound for switch/pushbutton and for relays is switch.wav, the sound for valves is valve.wav, the buzzer activates the sound horn.wav and the cylinder end position stop triggers cylinder.wav.
