E-mu Proteus 1 Pop/Rock (1989)
The Proteus 1 was the first of E-mu's Proteus series, and that line became the company's most successful. Introduced in 1989 as a 1U rackmount sample player, it was the cheapest way at launch to get high-quality, 16-bit sample playback. It was built from the same sound ROMs as the E-mu Emax II. You got 32-voice polyphony with dynamic voice allocation and 8MB of sampled sounds aimed at pop and rock music, plus dual stereo outputs and MIDI In/Out/Thru. The sources disagree on the sample rate. Some say 44.1kHz, others 32kHz, so take either figure with a grain of salt.
It launched at $1,495, which was considered a bargain when samplers were expensive. E-mu dropped the price to $995 by 1992. The Proteus 1 had no effects processor built in and no modulation routing, and owners flagged that as a real limitation. It was a workhorse anyway. Many people still describe the original as the sound of the late '80s and early '90s. Mix magazine (1994, p.46) noted the 32-voice polyphony and the acoustic instrument sounds, including grand pianos, organs, electric pianos, and strings, in a package weighing under 50 pounds.
Surviving documentation on the Pop/Rock variant specifically is thin. Most period coverage just calls it "the Proteus 1." The core facts above are well corroborated across multiple sources.
