Trip-a-Tron is a light synthesizer written by Jeff Minter and published through his Llamasoft company in 1988.
It was originally written for the Atari ST and later ported to the Amiga in 1990 by Andy Fowler.
The trial version contained no limitations, but registration was necessary to obtain the manual, which in turn was essential to learn the script language ("KML" - supposedly "Keyboard Macro Language" and only coincidentally the phonetic equivalent of "camel"), which drove the system.
The software has a usable but quirky user interface, filled with in-jokes and references to Llamasoft mascots.
"; the waveform editor colour cycles the words "Dead cool" above the waveform display, and the event sequencer displays an icon of a camel smoking a cigarette; and the image manipulation tool has a series of icons used to indicate how long the current operation is going to take: "Make the tea", "Have a fag", "Go to bed", "Go to sleep", "Go on holiday", "Go to Peru for six months", and "RIP"; and the scripting language command to set the length of drawn lines is "LLAMA".
