Oberheim 8-Voice
The name turns up in studio gear lists and eBay searches alike. The documentary record for this one is thin, and the archive won't pretend otherwise.
Overview
The Vintage Technology Archive has no verified fact sheet for the Oberheim 8-Voice. No manufacturer documentation, no confirmed production years, no confirmed voice count, no confirmed filter architecture. What the archive does have is a set of period magazine excerpts in which the phrase "Oberheim modular 8voice" appears. That appearance is the most useful thing on this page, because it shows where the name actually shows up in the historical record.
The clearest sighting is in Mix, in a studio equipment listing for Northeast Recording Studios. It sits in a run of gear that includes an OBXe, an OB-8, an Xpander, a Matrix 12, a Matrix 6R, a Voyetra 8, and a stack of Casio CZ and Ensoniq ESQ-1 instruments. The listing names an "Oberheim modular 8voice w/MIDI." Note the wording. It is not "8-Voice" as a standalone product name. It is "modular 8voice," which reads as a description of a configuration rather than a catalogue model number. At least one documented studio installation used exactly that phrasing, and the instrument was MIDI-equipped, which puts it in a working studio rather than a museum.
The second sighting is more oblique. Sound on Sound UK (May 1995, p.3) ran a dealer-style listing for the Oberheim OB-MX under the banner "Analogue is back!" In the same block sat an Emulator IV and a Studio Electronics SE-1. The OB-MX is a different instrument entirely, and the archive won't blur the two. The only reason to note it is that by 1995 the trade press was treating Oberheim's analogue lineage as a selling point, which is the context in which eight-voice Oberheim instruments of any stripe became collectible rather than merely used.
Beyond those two citations, the period excerpts are silent on the 8-Voice. DB Magazine (May 1986, p.53) covers a New England Digital Synclavier system and an Oberheim/ECC Matrix 12 in the same roundup. Modern Recording (September 1985, p.49) details the Matrix-12 and Matrix-6 with prices - $4,995 and $1,595 respectively - but neither mentions an 8-Voice. The Recording Engineer (December 1982, p.55) and Studio Sound (May 1980, p.93) excerpts contain no Oberheim eight-voice material at all.
The archive won't fill that silence with plausible-sounding invention. No voice architecture, no filter type, no keyboard specification, no memory capacity, no original price, and no production window are asserted here, because none of them are documented in the available sources. A collector who has owned one of these for decades may well know all of it. The archive would rather publish nothing than publish a guess dressed as a fact.
What the Archive Still Needs
To turn this into a real page, the following would need to be documented from primary or period sources: the resolved product identity and type; production years; voice count and synthesis architecture; filter design; keyboard specification; patch memory; original list price; known failure points and service notes; and any independent bench measurement from a print review. None of these are currently available. Until they are, the 8-Voice entry is a placeholder with two genuine period citations and a clear statement of what is unknown.
