The Atari Program Exchange (APX) was an interesting experiment in the early 1980s. Everyone who purchased an Atari 400 or 800 computer received a subscription to the APX catalog of "user-written" software, programs written by other people who had purchased Atari computers.

Mozart, Beethoven, and Bach never had it so good. With the ADVANCED MUSICSYSTEM, you can use your musical skills to their fullest. This program provides a complete range of possibilities, from listening to creating. You select your activity from a menu of fourteen choices. The editing function is one of the most interesting. You enter a musical note by specifying various parameters, such as octave, duration, dynamic level, and articulation. Every time you enter a note, the program reproduces it through the television speaker and displays it on the screen, where it can be easily modified at any time. ADVANCED MUSICSYSTEM can play very complex rhythms and extremely rapid tempos. Once you create music, you can listen to as many as four independent voices in a 5 1/2-octave range. You can watch a piano keyboard playing the notes with each of the four voices appearing in a different color. With the ATARI Paddle Controllers, you can adjust the tempo while the music is playing. Built-in synchronization functions let you construct a tape with at least eight simultaneous voices using an external tape recorder. ADVANCED MUSICSYSTEM lets you save music on a diskette, and merge files to create very large files. Depending on your system's memory size, you can store up to 6000 notes in a file. Using the automatic play feature, you may listen to the demonstration pieces included on the diskette.
