For use with Amiga's Joyboard controller. A prototype game that was mass produced! It seems that Amiga sent these carts off to a company that handled the task of labeling them. During this time Amiga was in trouble and the games never got labeled or retrieved by Amiga. Years later they were sold off as scrap to a videogame dealer who added his own label and sold them to the classic community. Gameplay is similar to the handheld game, Simon.
With this cartridge, the Odyssey 2 can play music thanks to the 3 stored tunes. The user can of course play its own music and record it. This introduction to computer music do not stop here: the user can play with tunes, modifying note duration, for example. The cartridge also provides training through a musical dictation feature.
An early music composition game released for the Atari 400 and 800, and one of the first applications which allowed users to create their own chiptunes.
