Take a weekend, and make something: that’s the challenge behind the Music Hack Day, which joins a growing phenomenon of events built around collective creation. (CDM held its own tangible interface hackday online, which I definitely hope to follow up soon!) Initiated by Dave Haynes of music sharing service Soundcloud, the Hack Day has already hit London. Many of the events were Web app-based and focused on consumption rather than creation of music, but we also saw a chordal synth plug-in and beer bottle percussion instrument.

The Berlin Hack Day, which wound up earlier today, offers still more projects focused on the creation side of music hacking. Having Ableton and Native Instruments as sponsors likely helped the mood. And as you’d expect from one of the world capitals of creative hacking, Berliners don’t disappoint.

Among the projects: a beautiful, elegant 3D sequencer, a fun bird-and-sky multitouch soundmaker with multitouch trackpad input, and a robotic xylophone controlled by monome. Someone even worked out a way to turn NI’s Maschine into a rhythm game, complete with Street Fighter sounds.

I’ve got some of my favorite projects here, but see also an eyewitness report (in English and Italian) at Audio News Room:

xylobot run by monome from robb on Vimeo.

Monomist Rob Böhnke and Ramsey Arnaoot created one of my favorite hackday projects so far: a monome-controlled robotic xylophone. The ingredients: one monome grid controller, one Java application for step sequencing to the output, one Arduino open source controller board, and one terrific xylophone “robot” made of an array of servos that strike the bars of the instrument. Oh, and some hot glue and wood, of course.

Audio loop

Of course, what’s especially impressive is nailing this in just a weekend – imagine what they could do with more time and iterations.

Proof that musical visualizers don’t always have to be trippy, futuristic, Tron-like 3D landscapes (and that’s me speaking as a fan of such things), Gernot Poetsch instead chose a whimsical environment with clouds and cartoon birds, inspired by the graphic identity of Twitter. (No actual Twitter is involved, meaning you lose the, ahem, unreliable, buggy, unfiltered chat network but keep the cutesy happy sky! Works for me!)

The visuals are built in Quartz Composer, which via OSC transmits messages to synthesis language ChucK for noisemaking. The surprise is, the multitouch input is not a Lemur or an iPhone – it’s the new MacBook touchpad under Snow Leopard!

iLoveAcid is a beautiful-looking nodal sequencer by Jakob Penca which uses wireframe “tracks” to guide music playback through a sequencer, transmitting events to your soundmaker of choice via MIDI or OSC. By using curved timelines and connections, it’s a veritable model railroad of music, in which formations combine to form more complex structures instead of simply stepping across a grid. Despite appearances, it is so far only two-dimensional – but then, the z displacement could easily be assigned to some form of modulation. I’m really eager to see the video of this.

One ingredient: Processing, which makes it easier to write visual code and to connect to Java libraries.

Project Page

The hardware controller for Native Instruments’ Maschine software drum machine has been adapted to other software, like Ableton Live. But this is surely the first time it’s been made into a game. Using Maschine’s MIDI output as a game control and sounds from Street Fighter, MaschineFighter is a simple, Simon-style rhythm game. Unlike Simon, though, there’s a twist – instead of rote patterns generated in advance, you face off against a friend and try to out-rhythm each other, battle style. I think it’s actually a pretty brilliant idea, and could become a new sensation for us electronic music nerds – not to mention, it’ll finally test our rhythm in a way electronic performance often does not. (Correction: It is Mac-only, making use of the PYMIDI Objective-C based library, which, since everything else that starts with “Py” usually means Python – a la jThings that mean Java – I assumed, incorrectly, was built on Python. But anyway, if you like the idea, carry on! And, actually, having a pure Objective-C CoreMIDI interface is also pretty awesome.)

Hoping for a video of this, too.

If you have a project that didn’t make this list, or if you add documentation after the fact, let us know.

Bored with mouse pushing and knob twiddling? The d-touch tangible sequencer / drum machine makes a cheap interface (with free downloadable software) for assembling sequences. Make some (attractive) blocks, set up a webcam, and plug into your computer. I took a first look at this tool last month, and noted its use in sequencing walnuts. (Yes, the ones that fall from trees.) Since then, the developers have been hard at work on updates. Enrico writes:

We just released the d-touch sequencer, a new, more advanced, audio application. In the sequencer you can record your own samples in real time.

We also have few updates for the drum machine, which should solve the activation problems we were having at the beginning.

Go grab the markers and the software, and you have your own webcam-based drum machine.

Should you decide to go beyond their free instrument, the underlying system is really quite sophisticated. Part of what makes it beautiful is that you can design your own markers rather than settling for predefined patterns, as with most similar marker-tracking systems. There’s even a tool for correcting problems in your design. The freely-downloadable analysis software is written in C/C++, but if you use another environment (like Max or Processing or Reaktor), you can simply pipe data to your tool of choice.

The drum machine and sequencer are available now, so go download them and let you know how you fare! System requirements: a printer, a webcam, and a PC/Mac. Enjoy!

For some hands-on impressions of working with these things, the excellent PC Music Guru has a great description of the experience. Or, if you read the language, there’s a Japanese-language hands-on blog entry.

ParamDrum TR Edition from Peter Dines on Vimeo.

Imagine a machine that lets you walk a thin line between control and chaos. You’ll be tweaking it, for sure – you’ll want to invest a sufficient amount of time shaping its sounds and adjusting its instruments to alter its flightpath. But once set in motion, it will give you variety and delicious insanity.

That’s the idea behind Peter Dines’ ParamDrum, a Reaktor drum machine with granular goodies inside providing sample manipulation and a set of clear sequenced controls for adjusting parameters. The “Param” bit refers to the parameters you’ll control – pitch + sample select + speed + size (of the sample) + smooth (granular) + swing. These parameters are unleashed against a sequence that you’ll likely never fully control – but that will never feel like it’s simply on autopilot, either. You can then load your samples into three players, which can be conceived as bass + clap/tom/snare + hat or something else entirely.

It may sound out of control, but “control” in the MIDI sense is essential. You can control step probability with MIDI velocity, tap in sequences with MIDI notes, and record playable automation with MIDI CCs from your hardware encoders. Pete has worked out a lovely template for Native Instruments’ Maschine controller, for instance.

ParamDrum, then, becomes a factory for variations. It allows you to iterate through plenty of results you don’t like to the one that’s perfect, for production or performance.

ParamDrum is a cheap US$12.50, though you do need a copy of Reaktor 5 (also included in Komplete) to use it. The upside is, it’s editable, and you get Pete’s immaculately well-organized patch macros, so it’s something you can modify easily or use as a model for your own patches.

Full details on Pete’s noisepages page, Modulations, which is also a new repository for his thoughts on sound design, Reaktor patching, SuperCollider learning, and other music technological geekery.

Planet ParamDrum

The other cool thing about ParamDrum in our throwaway technological world is that it’s already started to attract a little community of users.

Loopy C, master of strange sounds, has turned ParamDrum into his personal “hyperdrummer” for a track called Jah Frazzin Zooks, which he describes in a kind of experimental abstract poetry:

‘Frippish’, vari-tempo spectralisms meet Ornette Coleman-influenced electronica, hyperperformance machines jamming in the cafe at the end of the Universe (which for some reason look like fractal vaginas? (above)). Duo form.

The full track can be heard at his blog:
Jah Frazzin Zooks

Brettwiththedobro has a screencast (above) showing his own rig, with custom samples and the combination of Kore and Reaktor for control. (If you’re interested in the Kore and Reaktor combination, Pete’s previeous video tutorial is a great place to start.

This is a screen capture of Peter Dines Reaktor ensemble ParamDrum. I replaced the samples with my own kitchen/dobro sample map and hooked it into Kore to control various parameters. Fun, weird loops are a cinch.

Pete is also working with me on OpenSoundControl implementation in ParamDrum, which could enable cross-country ParamDrum collaboration, and via a project I’m building, visualization of parameters in Processing. Stay tuned.

Float away with Mujik… from The Amazing Rolo on Vimeo.

Musical technology is often designed to be “hard” in character. Interfaces are cold and technological-looking, futuristic like spaceships, or made to replicate antique gear to make guitarists feel nostalgic. Musical interfaces consciously avoid anything “childish” – calling something a “toy” being the worst possible insult – and they’re certainly never whimsical.

That’s why the real news about Mujik isn’t that it’s a new iPhone app, or that, after a few weeks of teasers, you can download it today on the iTunes store. (The app is free for a limited time.) The news is that it’s a musical interface with lightning bugs.

Mujik teaser… from The Amazing Rolo on Vimeo.

The creators, led by Yann Seznec, clearly had this goal in mind:

Do you want an iPhone app to make beats? And produce like totally awesome tracks with a zillion channels and plugins and automation and 808 simulators and stuff yeah? Oh. Well, this is not for you. Mujik is more than a music app – get away from fake sliders and buttons and enter the world of Mujik, with charming graphics, lovely music, and a wonderfully tactile interface. It’s not rocket science, it’s just fun.

Mujik is brought to you by Lucky Frame, a small team of awesome people based in Edinburgh, Scotland. It’s lovely here, you should come visit.

You can’t save yet, but I rather like that. And while you can’t yet add your own sounds (which they’re also working on), I actually can imagine this would be something you’d share with your friends who are intimidating by the arcane, unreadable tracker you have installed on your hacked Game Boy.

On the team: Yann Seznec is also known as The Amazing Rolo, who we’ve seen previously on CDM making a free Wii looping machine, and who recently did a three-part series just for CDM on the Maker Faire. (one, two, three)

Thanks to Chris Hahn on Twitter for the tip!

Dream Theater keyboardist Jordan Rudess and noise.io developer Amidio have made a crazy-looking hexagonal sequencer for the iPhone. It comes with plenty of samples and factory sessions if you just want to play around, but I imagine the greatest draw for CDM readers is that it allows exporting your own files via a WiFi server application.

(Ahem… cough… Google Android and others don’t require any special app just to get files onto your mobile device. Sorry, something got stuck in my throat. Cough… ahem… can we have a real, live audio system in Android now, please? Whoops, throat thing happened again.)

This application also works with Beatmaker, so you now have a pretty nice studio of mobile apps on the iPhone and iPod touch. If your arms have been cramped whipping out your laptop on the Chinatown bus to Boston (now with 6″ of legroom), this could be a huge help.

More features:

• Stutter, chorus, and bit-distortion effects
• Seamless loop creation you can use with Beatmaker or your own favorite audio production tool
• Cell randomization

JR Hexatone Pro is US$9.99.

Lastly, from Jordan himself, here’s a tutorial on sound programming with the tool:

Performance with Cubie from sadmb on Vimeo.

Music sequencing as a Rubik’s Cube-style game, or hypnotic, kinetic rotating wheels – your piano roll won’t know what hit it. New musical art is set to be performed in Argentina, but you can download both tools, free.

Computer interfaces for music date back decades now, but with ingrained notions of hardware sound sequencers, linear media like tape, and hundreds of years of notation in staves and bars, old habits can be hard to kick. Yet it seems that suddenly, a younger generation of audiovisual composers is exploding notions of how musical interface and sequence could work, fully embracing a virtual space in which they themselves have come of age.

Next month’s spectacular-looking 404 Festival could make anyone want to book a flight to Argentina. Two highlighted artists from this festival for me really embody the possibilities of new sequencing metaphors. Both are built in Java.

At top, Cubie by Sadam Fujioka of Japan is free, downloadable software that combines audiovisual performance and game in a rotating cube.

Cubie is a software instrument which provides innovative idea of musical performance, differs from existing musical performance system such as musical notation, DJ systems, DAW systems, etc… It has a novel concept incorporating a new interactive technique based on puzzle games. Music is represented from highly saturated colored letters on a 3D cube. Almost unlimited number of melodies and rhythms can be created from a combination of those letters, and it can be changed on real-time by operations based on puzzle game. Those playful operations push a performer to play repeatedly and get the skill of performing with Cubie. Cubie is free software and you can play just like sadmb do.

More information in both Japanese and English at sadmb site (with lots of other software, as well). Built in Java with the use of JSyn for synthesis.

If these cubes feel overly rigid to you, though, and you don’t like the mechanical repetition of these lines, enter the crazy, spinning world of Hiroshi Matoba.

Hiroshi Matoba: OVERBUG from antjeverena on Vimeo.

Overbug is a music-performance tool designed to compose Minimal and Dance Music.

Through looping and newly arranging sound patterns, called ‘Bugsounds’, the program creates complex, polyrhythmic sounds. Overbug differs from conventional linear controlled music sequencers, which arrange the sound into a linear timeline from left to right. In Overbug the sound arrangement of the repeating music loops is equal to the visual abstraction of circular actions which built the interface through circles.

I showed a very early sketch I was working on last year of a circle-based sequencer, also built in Processing, though (cough) my chops are nowhere near Hiroshi’s. I was more interested in using the circles to subdivide cycles, as in Indonesian music. Seeing this piece is a major kick in my pants to try to work on my project a bit more and go a different direction.

Here’s a demo video explaining how this works:

Don’t miss a terrific-looking exhibition of Japanese works and the rest of the

These two works clearly belonged together, but I feel bad for not featuring any Latin American (or Argentinian, specifically) work — those of you associated with 404, if you’ve got hot tips, send them in.

Gestural Music Sequencer from Unearthed Music on Vimeo.

Something as simple as remapping a single knob can give you new musical ideas. So expand that to entire gestures and live video input, and you can help push your performance in new directions and out of old habits. That’s why it’s always great to see projects like the Gestural Music Sequencer.

Built entirely in free tools – tools fairly friendly even to non-coders – the GMS lets composer and musician John Keston explore new ideas through gestures captured in a video stream. It’s easier to see than to talk about, so check out the just-completed documentary short by Josh Klos, with the aid of Julie Kistler and Brian Smith. (And yes, documentation makes a huge difference; we’d love to see more of this stuff!)

The ingredients:

• Processing, the free, multiplatform coding environment [site | cdmu tag | cdmo tag]
• controlP5, a lovely, light, quick-and-dirty library for UI controls
• Ableton Live – though you could substitute other software via MIDI, Live makes a nice, familiar interactive music engine

Lots more information on John Keston’s wonderful Audio Cookbook blog, which is fast becoming one of my favorite reads:

http://audiocookbook.org/category/gms/

And here’s a really lovely video that demonstrates what you can do with video. It uses a string of lights in a jar as the source. Yes, in a way, it’s almost like having a very focused random generator, but I think there’s nothing wrong with that. There’s an almost analog approach to seeing the source, and using that to organically create music.

GMS: Chromatic Currents Part II from Unearthed Music on Vimeo.

I have to observe, while this works reasonably well with MIDI, it reveals why standardizing on networked communication, as OSC does, makes more sense. In a world of software, “controller” can really mean anything you like. Control is increasingly about software talking to software – including when devices are involved, since they generally have a software layer of their own. Also, because sometimes it’s easier to code this with Processing than with Max, I can see some powerful uses of the Python-based Live API, which we expect to mature later this year. (Yes, the project called Live API seems to be in a holding pattern, but we may be able to work up a more complete, Live 8-ready alternative.)

By the way, our goal is to make noisepages a platform and collection of tools for people doing this sort of work (or anything creative with music and motion), even if you host your blog elsewhere. Stay tuned for the details on that.

The translation of music from something largely invisible to a physical object is oddly beautiful, even when imperfect. That’s part of why we’re working on the Tangible Interface Hackday – less than 48 hours away now.

Here are a couple of additional sources of inspiration as we prepare.

At bottom, Guy John has made a sequencer out of one of the world’s most ancient games, Go. Over two millenia ago, Chinese people were passing the hours playing this game, so it’s an incredible way of connecting our passtimes today with the leisure time of our ancient ancestors – and a sign that gaming is a part of culture that endures. It’s fitting, too, as a lot of computer musical interfaces can be thought of as games. This particular game uses Max/MSP/Jitter and the CV Jitter externals for image analysis, then translates the game into a grid. Guy’s idea is fairly early in development, so I actually think you could go all sorts of different directions with this basic concept. (As seen in Hack a Day at the end of last year.)

At top, the Graphite Sequencer translates optical images made in the electricity-conducting material to sound in a simple turntable. It’s lovely seeing these patterns as sound objects, especially since usually we go the other way (trying to find patterns to affix to sounds). The same basic graphite-conducting process is used in the business card PAiA kit we showed at a past Handmade Music, as well as the Drawdio pencil (based on the same circuit).

Graphite Sequencer (2006), as seen recently via the blog of the fabulous-looking Montreal Elektra Festival

I’d love to see people continue to combine these fairly basic analog-style techniques – or thousands-year-old games – with the newer digital approach. Let us know what you come up with, creative folk.

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

There are two grids, a “seed” sequencer that initializes a starting pattern, and a “playback” sequencer that provides feedback and control of the pattern that plays as the software runs. These two grids operate via principles of Cellular Automata, specifically the John Horton Conway Game of Life model, a evolutionary grid “game” that has been popular in computer music for its simplicity and the way it becomes animated in time. (The Game of Life is a “zero-player game,” which I suspect is probably the only truly fun way to play Monopoly.)

The playback sequencer is just a set of cells. To determine when each cell actually trigger events, you use a neat, color-coded trigger sequencer, which, as it sounds, is what calls MIDI events. Using the value sequencers for each color-coded swatch, you determine what that message is. In fact, if you wanted, you could use glitch-sequencer to control only effects parameters or envelopes instead of notes – or visuals, or anything that can be triggered by MIDI.

As you’ve got seeded grids doing their organic, unpredictable thing, you’ll likely want a little bit of control, too, and you have mechanisms for that. There’s a pattern length grid which determines pattern length in a more conventional way, plus a clock division setting for setting the master rhythmic division. There’s also a snapshot setting, which itself is presented as a grid so you can make little glitchy song arrangements by triggering different settings.

Where all of this gets fancy is the additional trigger settings. In addition to the MIDI event values, you get:

• Gate percentage for randomized probabilities
• Clock division
• Loop length
• Quantization for pitch (none, Ionian, Phrygian)

You can also manage the color-coded swatches as layers and mix their volume independently.

My one-line version of the manual: with that many parameters, screw around a bit and you’ll get something pretty unpredictable and glitchy.

This concept is related to other attempts to do similar, Game of Life-based sequencers, particularly Lazyfish’s Newschool for Reaktor, and (applied to an effect) Audio Damage’s Automaton. Because tiny implementation details can have a big impact on the resulting sound, though, it’s always nice having a new take on this, and I think Bret’s creation is unique in its ability to tightly control the sequence or completely screw things up with a lot of parameters.

It is all built in Processing, the free, open-source Java-based coding environment. I’m hoping to get a scoop on some of the experience Bret had with timing and Java, so stay tuned. Processing coders, the MIDI library Bret used is themidibus. There’s a trick to getting MIDI working on the Mac thanks to the fact that Apple decided to stop supporting a standard Java API in their implementation (doh!), but once you hurdle that, you’ve got Mac + Windows + Linux support – and this could be ported to Android, too, with a little work.

Wonderful things happen when you invite lovers of noise together in a room. Musicians and non-musicians, electronics geeks and first-timers, folks pick up a soldering iron — often for the first time — and cause utter mayhem. So we again had a fantastic time at Handmade Music last month. I’ve just gotten the photos in, so decided to share.

We’re looking for folks to bring stuff to Handmade Music on 4/16 – see the bottom of the article and give us a shout if you have software or hardware creations to share. They don’t even have to work, entirely – this is the place to find people to help give advice, so we like even partly-functioning inventions.

Even if you live far, far from Brooklyn (like back in Old Amsterdam), the featured March projects are within reach:

• Loud Objects Noise Toy was the star of the evening. Lesley Flanigan and Tristan Perich of Loud Objects — superstar composers and sound artists themselves — were onhand as patient teachers and guides in the ways of Noise.
• glitchDS on PC and Mac: The DS homebrew creator Bret Truchan delighted with not only his mobile gaming creations, but a netbook running a new PC cellular automaton MIDI sequencer, ported to Processing. More on that soon. (See the image captured by Make Magazine’s Collin Cunningham.)
• Pulsantes I got Jaime Munarriz’ strange Processing + Pd pulsating rhythmic toys working on a PC – thanks, Jaime, for the virtual contribution!
• jReality Peter Brinkmann demonstrated the sonic capabilities of audiovisual virtual reality framework jReality. Intense stuff – you don’t even need to use Cartesian coordinates. Elliptical, baby!
• Networked Objects: Eric Beug brought by his DIY wireless synth modules and an iPhone for control. This progress is under development, so I hope it makes a repeat visit.

By the way, in case you wondered what happens when a bunch of people play all their newly-built Noise Toys at once? It sounds something like … this (and sorry, my digicam mic was entirely incapable of capturing the resulting sonic chaos):

More photos from Collin Cunningham and our event co-host MAKE Magazine:

Hey, You! Yeah, You!

So, folks in automobile / railroad / Zeppelin distance of New York, we’d love to see what you’re working on, be it a Max/Pd patch, Processing sketch, circuit-bent instrument, DIY controller, sensor project, or wearable SweaterSynth. Definitely bring cables, and (if you’ve got one) a portable PA; otherwise plug into our PA and projector.

Next engagement: Thursday, April 16 (this coming Thursday).
