This third volume of Universal Synthesizer Interface delves further into early MIDI sequencing software for personal computers, focusing on Intelligent Music Software founded by Joel Chadabe in 1984. In a short period of time (1986-1990) Intelligent Music published a series of MIDI sequencing software titles that would have rippling effects throughout the music world: M, Jam Factory, UpBeat, MidiDraw, Ovaltune, Realtime, as well as an unreleased first version of Miller Puckette’s Max. These programs were a reflection of Chadabe’s desire to create interactive and intelligent algorithmic tools for home computers. Intelligent compositional tools had been floating around for decades in mainframe computer labs, but they had largely only been accessible to people working in academic or corporate laboratories. With the birth of Intelligent Music, these tools became available to anyone with a home studio. As the personal computers of this era had become less expensive and more accessible, they had also grown exponentially in processing power and seeming intelligence. In the music press from this time, we find the same two words used again and again to describe algorithmic computer systems: smart and intelligent. The tone of such articles may seem quaint by today’s standards, when AI and algorithmic control underpin so much of our technology, but the question of machine intelligence remains. Universal Synthesizer Interface VOL III Focuses exclusively on one of the more obscure of Intelligent Music’s software creations - UpBeat: The Intelligent Rhythm Sequencer, released in 1987, and hailed by reviewers of the time as “the world’s best drum machine.”
