Forget Sega vs Nintendo, it’s time for the battle of the old sound chips.

As I commented on the recently-released 8-Bit Computer Retrospectacular Squadcast (which I really do recommend you go and listen to – it’s our best yet), I was an Atari boy growing up, largely because that’s the system we had at home – there was none of this “own every system” malarkey that goes on now, partly because the systems were a lot more expensive in relative terms than today’s consoles, and partly because pretty much the same stuff came out on all of them anyway.

The bitterest battles that we Atari people fought were against the might of the Commodore 64, a machine of roughly equivalent power and capabilities to the Atari 8-bit series of computers. Both had very similar specifications, so it was common for owners of the two systems to try and outdo each other whenever possible. This constant effort of oneupmanship often took the form of trying to outdo each others’ graphics as seen here in this equivalent screenshot from Alternate Reality: The Dungeon on Atari (first) and Commodore (second).

Atari fans were quick to point out that clever programmers were able to get 256 colours on screen at any one time while the Commodore often seemed to have a more limited colour palette. But then Commodore would strike back with something like this shot, the title screen from Draconus (again, Atari first, C64 second):

Facepalm. “Hey, where’s all your colours now, Mr Atari?”

Graphics were all very well and good, but some of the bitterest battles were fought on the aural front, with both systems having a great sound chip far ahead of anything else at the time – Atari being armed with POKEY, Commodore with SID.

Okay, I may be exaggerating when I say “bitter battles” but it’s clear that there was some rivalry here. Some compositions sound clearly better on Atari while others are clearly superior on the C64. And it’s the SID chip’s sound which has endured in today’s chiptunes. There’s still POKEY players and archives out there, sure, but nothing on the scale of, say, the High Voltage SID collection, an exhaustive library of pretty much every piece of SID chip music, both retro and contemporary, you would ever want.

So, let’s take a look at a few examples. That is why you’ve read this far, right? To hear some funky old chiptunes? All right. Here we go.

Zybex – Adam Gilmore

Atari version:

C64 version:

Two versions of a cool song that you’ll be familiar with if you’ve read my past entries on game music. Adam Gilmore worked on a lot of music tracks for both the Atari and the C64 (including the theme for Draconus, pictured above) and was clearly very familiar with how to get the best out of both of them. It’s difficult to say which one is the best out of these two – or even if there is a “best” one. The Atari version, to me, has a cleaner sound, while the C64 version has some more interesting synth effects.

Warhawk – Rob Hubbard

Atari version:

C64 version:

Rob Hubbard was one of the undisputed masters of the 8-bit sound chips, with games featuring his music frequently marketed due to that fact – even if said music only appeared on the title screen, as was the case with most games, including Warhawk here. In many cases, the demands that pushing the sound chip hard enough to produce complex music put on the processor meant that having in-game music was often impractical.

I’ve gotta hand it to the C64’s SID chip here, the Warhawk theme sounds hugely better on it – partly because it seems that Hubbard actually wrote a more complex piece of music for it. Listen through, though, and you’ll hear the kind of effects that you’d expect to hear on a standalone synth – vibrato, tremolo, chorus, echo – it’s impressive stuff.

M.U.L.E – Roy Glover

Atari version:

C64 version:

A much older and simpler piece of music than the kinds of things Rob Hubbard dreamt up, the M.U.L.E. theme is still a catchy little piece. For my money, I prefer the POKEY version of this one as the sound envelopes that are used, particularly on the melody line, just give the whole thing a bit more “fullness” than the C64 version which sounds a bit “dry”.

Action Biker – Rob Hubbard

Atari version:

C64 version:

Oh dear. It’s clear where Mr Hubbard’s loyalties lie now, isn’t it? The pathetic, short loop used in the Atari version of Action Biker becomes an actual piece of music on the C64. Thanks. Thanks a lot.

Digital music

Bonanza Digi (Atari):

Digi Freaks Digi (C64):

What many people didn’t realise (even now, in some cases, and definitely not in the early days) was that both of these sound chips were more than capable of reproducing and sequencing sampled sounds, leading to much more realistic-sounding pieces. Of course, the sound quality is nothing to write home about, but there’s something gloriously 80s about the sound of “noisetracker” pieces such as these – a phenomenon which continued with the 16-bit machines, particularly with the C64’s 16-bit successor, the Amiga, whose sound chip was so far ahead of Atari’s equivalent effort for the ST (which in many cases sounded inferior to POKEY) it was ridiculous.

So there you have it. A few selected examples from the Atari and C64’s sound chip back catalogues. Back in the day, I was genetically predisposed to hate everything Commodore but on reflection, there are many examples of its superiority in music production. There’s certainly got to be a reason that the sound of the SID chip has endured as long as it has and remains popular to this day, while POKEY remains relatively obscure. I’ll always have a soft spot for those Atari sounds, though.

If you’re interested in making chiptunes, this plug-in for VST- and AU-based DAWs provides a good way to get started for low-cost, while fans of the old NES sound should check this (free!) one out.
