Except for computers and consoles, there are many other machines with real or mimicked soundchips inside. The recent DCM8 drum machine and the amazing Droid3 are examples of the latter, while Sidstation and POKEY.synth contain actual soundchips. But these are all sort of retrospective projects from the past decade or so. But what kind of soundchip-machines was around in the 80′s?
The most obvious example is the YM-soundchips. It’s a confusing field but, basically, Yamaha made these chips for both consoles, computers, keyboards and synthesizers. They mostly used FM-synthesis, which was a big part of the sound of 1980′s (and early 90′s bedroom electronica like µ-ziq). Yamaha synthesizers like DX-21, DX-100 and FB-01 used soundchips that a few years later were found in consumer products like X68000, some MSX-models and plenty of keyboards (ABA-88 lol). Later on, similar chips were also found in soundcards and mobile phones. *
The Remco Electronic Sound FX machine from 1979 was quite the noise maker. It was built on the SN76477-chip, which was popular for arcade games like Space Invaders but also used in ABC80 and Gakken EX. There are a few semi-recent DIY-projects, but I haven’t been able to find old consumer products with this chip. Recently, Panzer Party released a vinyl composed only with the Remco machine though.
It’s surprising that so few soundchips were used for both games and instruments. They continue to be two quite different fields. One consequence of that is that computer/console-based chipmusic was always separated from those who used soundchip-keyboards. For example, the techno-centrics of chipmusic (‘a soundchip is an instrument/medium’) wouldn’t categorize a DX-21 song as chipmusic.
Another consequence is an apparent gap in soundchip research. Many soundchips were never used for computer/game stuff and are (therefore?) not so well documented. Chips like M114S, CEM3394 or MC-3 2191 were found in keyboards, arcade games, toys and synthesizers. Some chips were found in speech devices, domestic robots, mobile phones and other thingies. Afaik, there is no thorough lists of such chips. There might not be 1.000.000, but who knows?
Well, there is Cyberyogi of course. He has an impressive collection of old keyboards that he also circuit bends (and makes squarewave music, not chipmusic). Describing the sounds, he often references POKEY (Simba – My MusicWorld, Hing Hon) and SID (Letron, PSS-100) but the hardware inside was either analogue or had obscure chips. There are probably people similar to him around the web, right?
(As some kind of consolation cross-over between synthesizers & computers, check out the HxC floppy disk emulator)
* I haven’t listened a lot to FM-music but to me it’s striking how different these chips were used by pop music producers and game composers. Virt argues that since FM-synthesis was difficult to grasp and had a crappy interface, most pop producers settled with using the preset sounds. (Reminds me a bit of how the TB-303 suffered from bad manuals and interface aswell.) Game composers though, were making far more complex things – sonically and musically. Was that because they were usually Japanese, and FM was very popular there, and they are better at enjoying unpredictable machines?
