syntauri

The Syntauri Corporation launched the alphaSyntauri in 1981 as one of the earliest computer-based digital synthesizers, turning an Apple II+ or IIe computer into a 16-voice additive synth via the Mountain Computer Music System sound card and custom software. Originating from Apple engineer Charlie Kellner's interface design for a Pratt & Reed keyboard and ALF cards, the system gained sophistication that led to its commercialization, with Steve Wozniak serving on the board at one point. Popular in academic environments for its affordability around $1,500 compared to high-end rivals like the Synclavier, it offered 8-note polyphony, multitimbrality, and sequencing, though the company folded in 1984 amid challenges advancing the technology.
