Nerds: It’s an OSC sequencer. It’s JavaScript-programmable for making your own generative music. It works with hardware and other software. You can use it in real-time.

Everyone: it makes spectacularly strange sounds out of spectacularly beautiful flows of geometries through space.

IanniX, the latest-generation descendant of work done by pioneering experimental composer Iannis Xenakis, has been evolving at rapid pace into what may be the most sophisticated graphical sequencer ever. Xenakis originally had to content himself to drawing elaborate, architectural graphics on paper, then later being one of the first to use a graphical tablet for interactive scores. IanniX, backed by the French Ministry of Culture, is now barely recognizable even from more primitive versions that carried the same name. But the idea is the same: graphical geometries represent events in pitch and time, now sequencing other software (any software that can handle OSC or MIDI) to produce sound.

Free on Mac, Windows, and Linux, and now with growing documentation, IanniX can be seen producing the kinds of warped sounds Xenakis made in his music. But it is one of the first steps toward a graphical sequencer that could be used in all kinds of cases. And it’s free and open source under the GPL v3.

I’ve included some of the recent videos that show off what it can do. I especially like the recursive demo. But since it runs on your OS — well, unless you’re sticking to your beloved Atari ST or BeBox — you can just go grab it yourself.

My sense is that IanniX could have implications even beyond this software. Imagine a greater variety of music software that begins to work in spatial and graphical interfaces, not just the traditional piano rolls and linear tape-style arrangement views. And imagine that such tools, using protocols like OSC and MIDI, begin to establish common means of communicating with one another over a network. (OSC and, in particular, MIDI, are in need of some evolution to fully satisfy that. But these kinds of tools might be an ideal way to prod that very evolution.)

Speaking of prodding, thanks to Mark Birchall on Twitter for reminding me to write this up.

Now, if I can just find some hyperspace portal to additional space and time to play with this properly… there must be a productivity jump gate around here somewhere.

Named for Curtis Roads, Curtis is an iPad and iPhone/iPod touch application that implements granular sound processing – a technique, imagined early on by the composer Xenakis, which divides sound into tiny granules, allowing more liquid modification of the audio. Roads brought this idea to digital synthesis, and the results can transform recorded samples in pitch and time.

Composer, producer, and sound designer Richard Devine has long made use of granular techniques in his own work, so it’s little surprise Richard is turning his sonic compositional efforts to the iPad app. The latest release includes a new sound set he designed, but he also writes CDM to point out a track he’s shared on SoundCloud, free to download and hear and for your remixing and re-compositional use.

The track is a composition of samples, and it shows just how much you can do with recorded audio:

This piece is a Acousmatic composition based on everyday found objects. I recorded various wine glasses, gears, metal, motors, Ratchets, chimes, croaking frog scraper, Indian bells, Tibetan Singing Bowls, Santoor, waterphone, piano, hematite magnets, processed voice, underwater ambiances, computer, and sprinkled bits of Buchla 200e/Doepfer Euro rack Modular.

All of the sounds originally captured at 24-bit 96khz with a Neumann RSM 191 A/S stereo shotgun mic, SMK4060 Stereo Matched 4060-BM Miniature Omnidirectional Microphones and Sound Devices 702 recorder.

If you want to try out Curtis, you can do so on both iPad (pictured above) and iPhone:

I love the geometric/vector-style twist on the wave display. New in the recent 1.1 release: pitch control, echo effect, volume control … and the all-important MP3 import. (Usually working with uncompressed files is more successful, however. With WAV or MP3 files, simply drag-and-drop files from iTunes.)

In other sound design experiments, Richard records an insect’s footsteps inside a box, recorded on a catch-and-release program, from earlier this summer.

Found a large Velvet Ant walking on my driveway today, and couldn’t help but notice the odd sounds this insect was making. The recording is of the insect crawling around inside a cardboard box, before I let it go back into my backyard. The Velvet Ant, also known as the “Cow Killer” is actually not an ant, but a wasp. I recorded this with 2 DPA 4060 Lav’s and Sound Devices 702 recorder at 24bit-96Khz.

The Harmonic Center of the Universe from Jesse Stiles on Vimeo.

This beautiful, meditative installation of choreographed lights and sound, by way of Rucyl and Saturn Never Sleeps, is the creation of Chris Harvey, Olivia Robinson, & Jesse Stiles. The Harmonic Center of the Universe evidently narrowly escaped destruction last year during a thunderstorm, but perhaps Art is as much repair as it is creation.

Artist Jesse Stiles specializes in such light shows. There’s a clear connection to the polytropes of Iannis Xenakis, with its own cascades of choreographed light – a reminder that lights can still have a place, even in an age of projection. He also writes experimental pop songs and does sound and music for IMAX films. (Yeah, Jesse, you’re someone we need to meet.)

Along similar lines, we saw the gorgeous balloon and music collaboration of Robert Henke and Christopher Bauder, ATOM, last year in Montreal. What strikes me about all these works it that the lit object and sound appear to fuse to an extent that these become either musical sculptures or a kind of sequencer in physical space. It’s remarkable that the digital can make musical structure more virtual, more invisible, or more physical – almost without consideration one way or another.

Synthesis geeks are creating some fun sonic toys for the iPhone. There’s no reason you couldn’t plug in an iPod touch or your phone into a mixer and use them in live or studio creations for a little variety. And as mobile platforms grow in capabilities, other platforms should be close behind. (Not to mention, you can always rescue an entire iPod or PDA and run Pd, often for just the few dollars an app costs!)

At top, the granular sampling app Curtis captures sound from a thumb piano. Curtis costs justs a dollar, but allows you to sample, then visually manipulate recorded sound, using granular techniques. A “smooth” synthesis engine is upcoming, but I rather like the lo-fi sound — hope you’ll allow us to switch engines with a toggle. As seen at Synthtopia.

The app is named for Curtis Roads, who did much of the seminal research into making granular techniques a technical reality. See his book Microsound
for an excellent overview of compositional, historical, acoustical, theoretical, musical, and, well, every possible aspect of this influential sonic practice. Have a look at the documentary on Roads and granular music we saw last month.

Segue – one early practitioner of granular music was Iannis Xenakis!

iGendyn is a new, free mobile application built around the GENeral DYNamic stochastic synthesis approach of Xenakis: “Imagine a set of control points (CPs) which together define the shape of a time domain waveform; with each new cycle through this waveform, their relative positions are updated using probabilistic distributions.” And yes, that’s GENDYN as in General Dynamic – not, in fact, a character from The Lord of the Rings.

Got that? In the default algorithm, X is amplitude, Y determines how quickly you scan through control points to produce the sound, and tilt changes probability. In other words, whether you understand the underlying approach or not (and hearing is always better, anyway), you can tilt your iPhone around and explore networks of probabilistic sounds.

Meanwhile, mother of all synth-geeky iPhone apps finally got its 1.1 update approved, so have a go with Jasuto 1.1 for a really terrific look at what modular synthesis could be. Jasuto also has a desktop VST version and the two will be able to integrate, so you have lots of possibilities here.

Thanks again for the mention of Tone Generation. I just thought I’d draw your attention to another related piece I produced with Ian Helliwell last year. It was called ‘Expo 67 – A Radiophonic collage’ and was a snapshot in sound of the Montreal worlds fair in 1967. Tristram Cary composed music for the Great Britain pavilion and much of this is used in the programme. If you listen closely you’ll also hear Tristam’s voice popping up.

Also featured are compositions by Hugh le Caine, Donald Erb, Eldon Rathburn, Erkki Salmenhaara & Erkki Kurrniemi, Giles Tremblay and Iannis Xenakis.

As always keep up the inspiring work with CDM. It is in my top 3 sites that I visit daily alongside Music Thing and Matrix Synth.

Give the music a listen:

And to help give yourself some visual inspiration, check out this retro-fantastic archive of Montreal Expo pictures, found (bizarrely) in a scrapbook found on the street in Cambridge, Massachusetts.

Unfortunately, I don’t think there are any images of Xenakis’ polytope. But, perhaps on a more realistic budget (ahem), this is how I want festivals of technology and culture to be. Oh, and it’s never a bad idea to invite Poland.
