Circuit Bending is the Art or Science, of modifying electronic instruments in unintended ways, mostly by connecting circuits somewhat random circuits points together with wires, switches, creating creating all new sounds and rhythms. Sometimes, a machine can be brought in a state where music and rhythms are improvised on the fly, in a semi-random manner. In other cases, a synth can end up producing very rich and organic sounds that sound nothing like the built-in instruments.

Safety tip: try to avoid making short circuits on the pins near the power circuits. Also, only do circuit bending on instruments that can run on batteries. Cheap, toy synths are better for that.

I discovered Circuit Bending by myself in 1991 or so (I guess before most of you were born). That's before the Web was invented. One of the first instrument I "bent" is a Casio SK-1, which incidentally, seems to be a favorite amongst modern circuit-benders. The Casio SK-1 is the first, affordable sampler keyboard.


An actual Casio SK-1 circuit board.

When the Web appeared and I started to "surf the net", I was pleased to see I wasn't the only one that was doing it. Now there's hundreds (thousands?) of Web pages dedicated to circuit bending, and even people selling "circuit bent" instrument with added switches, with their case modded and painted.

One important fact about Circuit Bending is that it mostly works only with old 80's electronic instruments, that had big circuit boards with multiple chips connected together by large circuit traces. I have a few old synths from the era, like a Yamaha SHS-10, and as you may know, a Casio VL-Tone though I don't plan on bending the latter.

Modern toy synths have combined all of these chips and circuits in a single chip, that has minimal inputs for power and keys, and audio output, making circuit bending close to impossible.

Zoskii is a tune that was originally recorded on tape, then digitized to 22Khz 8-bit audio somewhere in the 90's, using a serial based audio digitizer on a Mac Classic.

The version I'm presenting you was "modernized" using an equalizer and advanced reverb to make it stereo and smooth the low-resolution source. Some parts have been looped and some editing was done, but it's close to what the Casio SK-1 originally produced by itself, in the same order.

Here's the tune, Zoskii, in 128k MP3 format (2.3MB): Download Zoskii.mp3

Warning, it starts very loud Also, some of you may find this tune extremely annoying

Personally, I like it, but I guess I've learned to.

What I like is how the SK-1 is improvising using quarter-tones, making subtle and somewhat smart variations in the pitch and melody, but that may be the reason why some may not like it, since it can sounds "out of tune".

Anyhow, I hope at least one other person can appreciate its "gritty" sound

I like it...

This circuit bending thing seems interesting... I have an old yamaha pss-30 around here and I might give it a try... But I'm afraid I'd permanently damage it or something...

Is that also available in nsf? Or spc?

In all seriousness, though, that sounds really weird. Especially when I unplug my headphones... These speakers have too much bass.

I like it.

Well, if you avoid the power circuits, it's very hard to damage a synth like that, even though an electronic engineer would probably disagree. From experience, and from what I've read on the net, damaging a synth with circuit bending is a very rare occurrence. That being said, I can't guarantee it won't break a thing :/

This Zoskii tune is all pretty catchy, at least the main part. It gets a little weird at some parts, which I think could give me a headache before too long.

Circuit Bending is a pretty cool concept though, I'm just afraid that I'd fry the thing.


When you say the main part, you mean the loop at the start and end of the tune? Yeah it's definitely the best part.

At the time, while I was circuit bending the SK-1, I found this really catchy riff (the one we're talking about) and started recording. Then by accident I moved some wire and it transitioned to the second part (the "whiny" part). The transition is quite nice in itself, but after that I lost the wiring that caused the first part, and the only reason you can hear the first part and transition again in the middle and at the end of the tune is that I manually inserted it there, to make the rest more varied and "tolerable"

Stuff like this makes me wish I got in to music while I was younger.

wow... I like how it doesn't have to be perfect, like music seems to have to be today.
If it was in a game, it would be great for a desert type area

If you're really into circuit bending, check this site out: http://weltenschule.de/TableHooters/instruments.html

I like checking this out when I'm bored, it's really interesting.

As for the song... ehh... it's kinda weird. It's a little too much for me.
But if you like songs like that, try checking out Casio Core.

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
