Handmade Electronic Music: Bending vs Building

April 29, 2009

In 2006, Nicolas Collins‘ released his book Handmade Electronic Music (Google’s pirate copy here). Yesterday he presented the second edition at STEIM in Amsterdam, an institute which has been active in this area for 40 years already. Collins has similar authority on the subject, being a professor of Sound and a very experienced low-level sound art performer.

I haven’t read the book, but if little-scale lists it as an inspiration it is probably a very good read. I went to the presentation expecting to get an insight into this practice, since I think it is interestingly placed inbetween chip music and circuit bending. It is more than just circuit bending because it doesn’t rely on readymade systems (just components). It is like chip music in the sense that all the audio/music is handmade; it doesn’t use large chunks of sampled audio or algorithmic compositional elements (like most other electronic music).

Nic (btw, not Nick) started with two performances: one with a group of people poking a circuit board to make sounds, the other one with a lit candle performing similar sounds. Fire-driven music is nice stuff and with Nic blowing wind on the candle, the sounds would change. So now, in a broad sense, there is chip music made with fire, wind and water. Hope to see more elements!

“Last time I was here I talked so much, so this time I will show examples instead”. Assuming that everybody was there the last time, Nic instead ran the DVD included in the book. It was like a very long Youtube session with 1 minute clips of handmade electronic music. Definitely very interesting, for a while, but it was not what I was hoping for. The clips were more like tech-demos and noise than performances with musical instruments. That statement is of course leaning towards musical conservatism, but sometimes we need that too, eh? : ) I can continue along those lines by saying that most of the devices made very similar sounds. You know, those scratchy and pitchy pulse wave sounds that the Cracklebox at STEIM made already in the 1970s. If you’re not in the mood, it gets pretty tiresome after a while..

But I also think that chipmusic and demoscene practitioners could learn a lot from the conceptual and noisy ways of sound art and circuit bending/”building”. It is funny how circuit bending, chip music, and the demoscene is sometimes presented as related to eachother, eventhough they are so different. Chip music is (too often) about 4/4 happy bleep pop and using default samples of LSDJ. Demoscene music is (too often) about perfectionism and competition. Circuit bending is (too often) about tech-concepts and predictable noise.

What they do share, is a fascination with the possibilities (aka limitations) of hardware that is old or open (enough). In the demoscene, hardware is losing some of its priority to make room for emulators and design/concepts instead of coding brilliance. Chip music seems to get more tech-fundamental at the moment, and as for circuit bending I guess that hardware will keep on playing a vital role (eventhough “software bending” such as glitchNES has appeared). What it ultimately amounts to, is a discussion on what a technological system is and also if/how a computer composer can operate independent from capitalism and culture. (any suggestions? hehe)

I think that “handmade” goes just as much for software as hardware. You often forgot the extent to which some chip music is handmade. At the end of the day, that might be more relevant than the mantra of “commodity subversion” and if so, maybe chipmusic is more similar to circuit “building” than circuit bending. Well. Just continuing the ramblings about how to contextualize and explain chip music so we don’t have to be blamed for being DJs/gamers on stage. We can play as much or as little live as other electronic musicians, damnit. Ciao gringos.

Sequencing Computer Peripherals

April 23, 2009

I just found a version of Bohemian Rhapsody performed by an Atari800XL, 8″ floppy drive, TI 99/4a, 3.5″ floppy drive and four HP ScanJets. It’s apparently the hottest youtube-clip in Canada right now, yip yip! The same author also has Funkytown performed by C64/modem/printer and TI99/4a. Mentioned as his inspiration is James Houston’s Big Ideas (Don’t Get Any) which had a slow start of its Internet career, but has received lots of internet attention by now. It’s James’ final project for design school, so the visual aspect is also well worked through. A very special clip. It’s a ZX Spectrum with scanners, harddrives, and printers that performs a Radiohead-cover. James “placed them in a situation where they’re trying their best to do something that they’re not exactly designed to do, and not quite getting there”.

While many chipmusicians claim to re-purpose technology, sequencing computer peripherals like this doesn’t even involve a sound chip! The first time I came across it was on the Commodore 64, where software would play music with the drive header. There is a youtube example of the 1541 drive playing Bicycle Ride For Two (originally from the first “chipmusic” record Music For Mathematics, 1962). There is also atleast one application to do this: 1541-music (1987), but don’t test it if your diskdrive is dear to you.

Back in the days, computers did not have a DAC (digital-to-analogue converters) which turn bytes into vibrations for loudspeakers. There is a peculiar story from 1966, when Tanzanian visitors to Sweden were treated with a printer playing their national anthem! Supposedly, this was the easiest way to make computer music for these engineers, although there was squarewave music elsewhere in Sweden at the time (where some pretty hardcore arpeggios were eventually made).

At the time, keyboards and screens were not common place either. Even in 1975 the Altair 8800 was just a box with switches and lights. The American hobbyist Erik Klein bought this computer as a kit and “30 hours later it was running with only one bug in the memory!” He happened to notice that the Altair was interfering with the nearby AM-radio, and he figured out how to control the tones and play his own music – “with nary a glitch“. Possibly this is the first piece of computer music made outside academia/art/videogames. But, the sounds are not digital and an AM-radio is not really a computer peripheral anyway.

On another (ir)relevant note, peripherals have been re-purposed in the C64 demoscene. If you run out of memory or CPU-power on your Commodore 64, you can use the 2 KB RAM and 6502 CPU inside the 1541. One example is the demo Deus Ex Machina (C64 2000) by Crest. Jeff’s song “Crossbow” apparently plays from the diskdrive.

So, the lesson to learn is that computer peripherals can be great tourist attractions and can probably be used for even more bizarre things. I’ll finish off this post with some more examples of music with peripherals.

Composing:

  • Paul Slocum and his dot matrix synth, used for exhibitions and the excellent music project Tree Wave.
  • Sue Harding’s Dot Matrix music. youtube. Does not involve any programming, but rather trial and error style by printing images and see how they sound. Notice the Amigas!
  • Little-scale has a number of printer projects and an arduino tutorial aswell.
  • Half Arsed Printar Shreddage at youtube. Feeding samples into a dot matrix printer head.
  • Gijs Gieskes’ Image Scanning Sequencer
  • Amiga-drive performing El Condor Pasa (stepmotor) youtube
  • Amiga-drive performing a melody (“spinmotor”) youtube
  • Amiga-drive playing a sample. youtube

Software:

  • Tape Composer (C64 2009) Compose music for the Datasette (the “tape deck”). It plays back either through the motor, or through audio tape decks (the music you make is saved as data that sounds like your music, uh when you play it as audio) more info here. When I tried it I didn’t get much sound out of my datasette.
  • Tap Music Composer (ZX Spectrum 2007) I forgot how this works, but the results sound like data-cassettes in the right tones.

Children with Chips taking over after Children of the Chip

April 17, 2009

I remember reading a thread on some Amiga forum a while back, about a dad who got his kid a Commodore 128 (or something similar). The datadaddy was surprised by how engaged his son got with the old computer. The Playstation and PC next to it were turned off. The C128 obviously had something that the newer machines were missing. Possibly it was just a temporary fascination, but it was definitely more than nostalgia or sarcasm, or gaming. When this kid and his friends were confronted with BASIC (the built-in operative system of the C128), they started exploring the possibilities of the computer. This was just something completely different than ultra-immersive blabla-technology. I think this is a very relevant idea, one that right now is explored by the Playpower project: 8-bit technology has unique possibilities!

Sure, these old systems are not “user-friendly” and its programming abilities might not attract people that are not into tech-logics. But in the 1980s, thousands of children/teenagers had the priviledge to explore ground-breaking machinery to learn how a computer (not an operative system) works. Ever since, computers have been debugged, standardized, normalized, controlled, patented, censored, etcetera. To most people this constitutes progress, but that is of course a politically and culturally biased statement. There is nothing limited about 8-bit technology per se. It’s still amazing technology for children or some people in non-computerized areas. And of course to those people who like working close to the machine without wearing a corporate condom.

I just realized that there are in fact three exhibitions that independent from eachother, concerns children and 8-bits. BliepBliep! is a “hands-on exhibition for the whole family” in Rotterdam (nl), running until September. Its theme is the sounds of computers and videogames, and apparently gives you some kinds of composing possibilities aswell.

ComputerMusic4Kids was made by Marieke Verbiesen who is an artist, researcher, teacher, and one part in VideoHomeTraining. Here you have a custom built matrix step sequencer where you can organize sampled sounds from a specific machine. There are 11 machines to choose from, from 1972’s Odyssey to 1989’s Gameboy. I actually tried an early version of this, and I think it’s something that kids definitely would get into. And grown ups like me, too. ComputerMusic4Kids is currently not on display anywhere, but watch out!

21st century retro-futurists is part of Art Venture, an exhibition in Roanoke (us). It was curated by Jeremy Kolosine who is most known for getting the 8-bit Operators together, but is also one of the most experienced composers doing 8-bit music today. This exhibition aims at getting people involved in making music and video with 8-bit technology and circuit bent objects. There are both workshops and installations, so this definitely seems like one of the more ambitious chip style things that have been executed in the art world. Any other suggestions?
