Digital technology has the power to transmit information more efficiently, to make the invisible visible, and to express new things. It can also be pushed so far to the limits of actually transmitting information to be meaningless. It can push well beyond what we can even perceive in a useful way. What’s bizarre and wonderful about Johannes Kreidler’s work is that he’s not afraid of pushing toward that boundary. The results may have only a shred of remaining meaning, or be intentionally, comically meaningless. But he’s nothing if not inventive.

The video above, politically speaking, is Not Safe For Anything – where else can you bring up Hitler and Britney Spears and condoms? But the only visually tantalizing information is the brief view of a condom speaker membrane and a chest with pasties.

The creations range from:

An oven pipe imported in 1972 from Alaska to New Zealand, vibrated at 574 cycles per second using a gasoline motor. Then, in 2003, this recording was manipulated and filtered on an old atari computer using hacked software.

…to:

Immanuel Kant: Critique of Pure Reason, played 22,000 times in one second (audible only to bats).

The controversial nods and humor aside, I think this really does say something about time and data. I could tell you, but I’d need a microsecond. Let’s just avoid any mention of datamosh.

Johannes Kreidler does know how to encode information in useful, accessible ways, too, however. He’s done just that with a terrific book on Pd (Pure Data), the open source, visual programming environment in which he created works like the one above. Can’t dance to it? You can do other things with Pd, too. You can dance to it? Then, by all means, go for it:

If you hate modern samplers with all their supposed fidelity, longing instead for the glitchy digital distortion of samplers past, a DIY project has brought you the sounds you love. “Where’s the Party At?” has been inspiring tingly sensations in digital lovers since I first wrote about it in September.

Now, the kit version is shipping. It’s a unique-looking combination of reliability and sonic unreliability, good open source design engineering and, as the creator puts it, a certain “crustiness.”

Apocryphal Feature List and General Horn-Tooting:

• 8-bit max sample depth, 1-bit minimum.
• 20kHz (or so, user adjustable) max sample rate, no minimum.
• 512k SRAM, about 26 seconds (minimum) or sample time.
• Big, versatile 6 button, 7 knob, 8 LED user interface. For Cavemen.
• Even more big and versatile full MIDI control in and out capability. Fully sequenceable. For people who use Live and general bespectacled electronic music nerds.
• Sample banking — multi-timbral recording, playback and audio processing across all banks.
• Sample multiplication, XOR, ABS, and all sorts of other weird sample processing and cross-modulation.
• Real time overdubbing.
• Preferences saved in permanent memory.
• Hackable analog clock source which can be syncronized to other synths.
• Non-Hackable crystal clock source which will always do Exactly What You Tell it.
• Programmable clock jitter, bit rate reduction, aliasing, and sample clock errors all adjustable in real time.
• All the normal backwards masking and half time and typical sampling features common to many commercial samplers.
• On-The-Fly Granular reconstruction of samples.
• Full pitch control of samples.
• Self test mode for debugging.
• 2.8Hz-357kHz frequency response (measured).
• Sub-audible noise floor.
• Looks nerdy and attracts people with stringy hair. Possibly bad skin.

Where’s the Party At, Hardware Version 1.01

I also love the bag of shiny hardware for aiding in making yours nice!

For those of you longing to mutate beats like so many promiscuous Petri Disk bacteria, programmer Bret Truchan is a kindred spirit. Bret has created a series of instant experimental classics for the Nintendo DS: glitchDS, a cellular automaton music sequencer, repeaterDS, a visual sample mangler, and cellDS, a grid-based sequencer you can script in Lua.

The Nintendo DS is portable and cute, but it’s not normally open to running software without the Nintendo Seal of Quality. (Insert snickers here.) To run Bret’s software, you need specialized hardware that fools the DS into running software. The DS isn’t entirely stable when it comes to things like timing, either, and it doesn’t have the flexibility of computers.

Enter the netbook. The netbook is nearly as portable, completely open to running whatever you like on Windows or Linux, and boasts easy USB connectivity, a big screen, and … well, you know, all the things you like about laptops. When it comes to musical productivity, much as I love the DS, the netbook has a whole lot going for it, and still has that added ultra-portability that makes you feel you can make music anywhere.

Bret recently made the jump to desktop software with Quotile, a step sequencer you can live-code for mighty morphing beats. Quotile is cool, but for many, glitchDS was the star. Now you can run glitchDS anywhere – just the job for a laptop you were going to retire, or that new netbook.

Not Sequencing, Glitch Sequencing

Glitch-sequencer is a sequencer, so it needs to either talk to a software synth or external hardware. Bret likes to hook it up to his machinedrum and monomachine. Our own Handmade Music event was the (unofficial) first public outing of the software, and included an HP netbook and the machinedrum, which makes for a sweet, mobile combination.

Despite the appearance of a grid and sequences of levels, this isn’t an app that works like a conventional sequencer. Here’s the basic breakdown:

• Cellular Automata via a seed + playback grid
• Trigger and value sequencers to determine which MIDI events the organically-generated mutations produce
• Pattern length, clock division settings for setting metric values
• Sync settings

What’s in for this season in music software? Cellular automata. You may have been exposed to a cellular automaton in the classic Game of Life; it’s basically a very simple biological simulator exposed as an intuitive, 2-dimensional grid of squares. If tic-tac-toe, Charles Darwin, and a petri dish of bacteria got together in one wild evening, you’d come up with something like this as a result. The Game of Life has been around since mathematician John Conway invented it in 1970, but lately it’s been cross-bred with music software to help patterns escape the rigid, boring repetition of traditional sequencer grids.

Cellular automata is in fine form on the beautiful, strange homebrew sequencer for the Nintendo DS, GlitchDS, which has had ongoing updates. It’s still fun as ever in Reaktor 5’s Newschool preset (old news, but enjoyable nonetheless). But in what’s so far the most anticipated plug-in release of the fall, CA takes on particularly powerful sonic possibilities in the first “experimental” release from beloved plug-in boutique Audio Damage:

Automaton [Product Page, Mac AU/VST; Windows VST]
Cost: US$49.99

Since the cellular automata grid can control anything, it’s what you hook it up to that matters — and that’s especially important, because it means instead of a set of knobs or sequence grid doing the same thing over and over and over and over again, CA “evolves” on its own, bringing much-needed change to your music. Automaton is a combination of a flexible CA sequencer with four effects:

1. Stutter (modulates a buffer, so you can combine Automaton with existing beat loops and patterns)
2. Modulate (a self-modulating ring modulator)
3. Bitcrush (which includes AD’s own “error” setting)
4. Replicate (based on their Replicant effect, which goes even further in the beat slicing realm a la Ableton’s Beat Repeat)

I’ve been playing around with the beta, and it’s just fantastic. I hope to finish off some special CDM presets and share them with you, though I’m a bit behind — let’s see if I can top the presets that come with the tool. One of the hallmarks of Audio Damage’s software in VST format is lots of MIDI learn support, and since it supports VST automation I anticipate some fun combining this with Kore. Either way, think easy tweaking and live performance control.

Now, question math geeks: any other cellular automata aside form the Game of Life that work well with music? I’m sure there are some experimental music projects out there that have used other CA, so link away.

Here are two tutorial videos of the tool in action, in case you haven’t seen them already:

One box, many sounds, all toy-like and strange. Such is the vision of the Glam Machine. Norman Fairbanks, the man who brought us the all-Tenori-On album, has been teasing this creation, housed in a lovely wooden box with a giant VU meter on it, for a few days. Now we finally get to find out what it is — and apparently it was all inspired by Norman doing an interview here for CDM.

Imagine a semi-modular box with glitchy sampler and the repurposed, Frankenbending sounds of electronic toy guts:

The instrument will consists of three main sections: two modified toys and a lo-fi sampler. The first toy is a complex modern educational toy that can be altered to produce amazing organic soundscapes, sweeping orchestral sounds and strange percussive loops. It also has a stereo output, which is rather nice. The second toy, in contrast to the mellow tones of the first, produces harsher sounding staccato blips, crunches and bleeps. This section can also make several different animal sounds. The sampler can record up to 20 seconds of audio, either as one long sound or four shorter ones. This is useful as the unpredictable nature of circuit bending can sometimes make it difficult to recall a particular sound. Last but not least: there is also a loop function.

Norman did the brief, but the hardware-constructing mad scientist is an East London-based fellow named Dave Cranmer, aka nervous squirrel. (See the interview he did with Future Music mag, and the many creative projects he’s working on on his site.)

Here’s a look at the insides, plus a video of another Nervous Squirrel Creation in action:
