It is widely assumed that the Remote uses Bluetooth technology to transmit information (for example: Button 1 pressed, Button 3 pressed) and Freddie has a program on his computer so that before each show, he is able to assign each button a task (for example: Play Random Dancing) to complete. The best languages to use for this program (if Freddie programmed it himself) would be Assembly, C++, or REALBasic. There are also ready-made programs (AutoHotkey for Windows, built-in system features for Linux and OS X) to play the sound effects when the buttons are pressed, if the remote implements a bluetooth keyboard interface.
