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:

Berlin Hack Submissions

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.

Code, hardware, and software: Hack Days are all about getting actual stuff made. Berliners, the Music Hack Day that took place in London at The Guardian now gets underway in Berlin this weekend. For anyone who thought the first event was overly Web-centric, there are some new players in Berlin. Ableton is a sponsor, and Ableton, Native Instruments, and RjDj are all presenting hack sessions (in addition to the more Web-focused / consumer-focused 7digital, Songkick, Cloudspeakers, Mufin, SoundCloud, and Echonest). The awesome German musician magazine DE:BUG is also in on the action. I also see our friends at Future Audio Workshop (developers of Circle) in the lineup.

Weekend schedule

So, German readers, who’s going? I’d love to have some spies tell us what the discussions are with NI and Ableton.

I’m, as always, interested in how we can get past geography and share work internationally. So if you’re doing a project, be sure to take lots of pictures, screen caps, code pastes, and the like, and we’ll feature your work here on CDM.

Future events are planned for other cities, and I hope CDM will be involved in some of them. Boston will be the first US event, but it’s on a date I can’t make it. Anyone have a space here in New York you’d like to suggest?

Showcasing amazing projects is a good thing. But we know that no creation emerges fully-formed. They start from nothing, with lots of mistakes along the way. You get help and ideas from other people. And you need time.

So this month’s Handmade Music in Brooklyn we’re declaring an Open Lab. Got a kit lying on your shelf, waiting to get made? Got a half-finished project that needs fixing? Just want to hang around some musical and visual DIYers and see what they’re up to? And just need a few hours to make some progress? That’s the idea.

Software projects, hardware projects, gear hacking, circuit bending, coding, patching in Reaktor or Pd or Max – it’s all welcome.

We also have a very special guest this month in the form of Morgan Packard, a talented multi-instrumentalist and computer musician (video at top, with live visuals by superDraw creator Joshue Ott). At 7:30p, Morgan will show off his free Ripple musical environment, built on the powerful open source SuperCollider code-for-sound platform. It’s a great chance to see what SuperCollider can do, how a scratch-built environment can open up musical possibilities, and what you can do with Ripple yourself.

Full details: Handmade Music Brooklyn: Open Lab, Featuring Morgan Packard’s Musical Code [handmademusic@noisepages]

Facebook Event Page

The whole event runs 6:00p-11:00p at 3rd Ward Brooklyn. As always, it’s completely free. Be sure to bring your projects and the tools you’ll need; we can provide power, a PA, space, and other folks to hang out with. And we can help give you an excuse to set aside a few hours of time.

We’ll also be taking notes on how the setup works, as we know this may be something other Handmade Music events want to try in your neck of the woods.

Electronics and code and whatnot are great fun, but a lot of people want to know, how can they add actual, physical motion to a project? I’ve rounded up the last few odds and ends from the London Music Hackday organized in the offices of The Guardian, and came across Alistair MacDonald and Mr. Duck’s Percussion Machine, which uses Arduino with servos to strike beer bottles.

Here’s the perspective of the non-techie on the affair from the newspaper’s music blog:
Beats and geeks at Music Hack Day

Of course, I’ve heard from at least a couple of people that for this audience, you’re not entirely ready to do all your work in the cloud. APIs. Yawn – the computer musician audience still is happiest with as much CPU power as they can muster, live sound making in native code on a local machine, and, you know – rocking out. But that to me is a bit interesting in itself.

Also from the hackday:

While the Arduino is ideal for hard projects, software projects turn to the fuzzy textile-friendly Arduino LilyPad. (Side note: the LilyPad turns out not quite the perfect tool for all occasions, and a discussion of all soft electronics may be what’s next. But it is a good starting point.)

Rain Ashford used the LilyPad to make an interactive felt cat named TwinkleStarduino. Just don’t cross the streams – er, threads: “Yep – all the components are connected by conductive thread – none of these must touch each other or you’ll get a short circuit – which is a challenge in itself :-)”

Rain’s blog post discusses some of the challenges of the project and some of the things that went wrong, which I quite like. (One of the goals I set out for our own music hackday last month was to break s***.)

Musichackday 2009 – my hack: TwinkleStarduino [I like cats]

For fans of RjDj, the interactive music engine for the iPhone and iPod touch, here’s an example of the sort of work you can hack together in a day with the help of patching environment Pd:

Lastly, photos by organizer Dave Haynes:

And yes, it sounds like the EchoNest is interested in doing a hackday here in America. And with the help of the site we’re building, noisepages, we definitely plan more hackdays on CDM, too, with a CDM-style focus. Stay tuned.

The Music Bore – Video 2 from Nicholas Humfrey on Vimeo.

“I’m sorry, Dave, I can’t allow you to listen to Coldplay.”

What would radio be like if playlists were not only robotic, but had robot DJs pulling information from the Interwebs dynamically? That’s the question asked by the winning team at London’s Music Hackday last weekend, which created an epic mashup of data sources to produce a voice-synthesized IRC chatbot that researches and plays music for you.

Music Bore

Music Bore was just one of a number of projects developed in the weekend of musical hacking, some for listening, and at least one (a fantastic and free synth plug-in) for what we really like – production. With some of the world’s top musical coders in attendance, the results were amazing, even if not all projects were entirely finished. (Hey, that’s why they call it hacking.)

You can check out the full list on the wiki, but here are some favorites — and if you were there, do shout out to us as you put more documentation up of the event and projects.

Harmony Box by Dave and Mike is a synth plug-in for Mac (AU/VST) and Windows (VST, thus also Linux) that quickly creates lovely chords. I love the simplicity of the instrument – really lovely work, gents – and I think I may actually use it on a project. They accept donations if you’d like to see this instrument mature. Of course, with everyone else doing Web mash-ups, this didn’t win, but it’s more up our alley. (Web 2.0 – meh, whatever.)

The synth has its own project blog:
http://davenoise.com/blog/

Other winners (in our book, and as recommended by Harmony Box co-creator Dave Gamble):

LonelyHarps by Jamie Hollingworth and David Padbury is a Last.fm-based tool concept that helps you find dates – and choose the right tracks to set the mood – using music for compatibility. And, really, do you really want to date someone who doesn’t have musically compatible tastes? (I’m sure it’s just because they spotted lots of hotties on Last.fm, but…) The only bad news: the app didn’t actually get fully made yet, but we’ll stay tuned, gents. They do have impressive-looking formulas.

Music Zeitgeist by Cristiano Betta visualizes lyrics by decade, such as the 1980s, above. (Yeah, it was all about wanting and karma, the 80s.) Check out the project directly.

Theremag by Jono Cole and Jonty Wareing of Last.fm is actually the app I most want to see, but there’s no documentation yet. It’s a Theremin emulator on the Google Android-based HTC G1, with an unusual sensor — the built-in magnetometer (the one that normally acts as the compass) which was used to pitch-bend Michael Jackson. Once they get documentation up, expect to see it here. (I love that magnet sensor, too. Good fun.)

iPhone Music Visualizer by George J Cook and Matt Biddulph grabs Soundcloud files, analyzes them with Echonest (which recently got an iPhone-friendly Cocoa API), and then plays them back with a visualizer. It looks like a great place to get started if you’re planning on building something similar yourself.

In fact, it’s well worth checking out the wiki not only because some of the projects have (okay, sometimes-sloppy) source code, but point you at the resources you’d need to tackle something like this yourself if you’re a coder. And the event prompted a lot of folks from Last.fm to Echonest and BBC and others to get their APIs together.

It’s a terrific idea, and it sounds like we need another music hackday here. (Press releases, ahem, claimed this was the “first” music hackday, even though we’ve done a global event ourselves, but who cares — let’s do more!)

New York would make a nice base of operations for a similar event because a lot of folks with interesting APIs are here (or in nearby East Coast towns), but I think it’d be great to get more people online and not just in one locale.

What think you, sirs and madames? Tips on how we could make an online event work?

Fritzcrate Project / lusidLearn Early Demo from Michael Schieben on Vimeo.

Knobs and faders can be rigid. Fancy multitouch devices can be expensive. But for the cost of a webcam and some spare materials, you can build computer interfaces with objects around the house, thanks to the power of open source software.

In just one day, a group of artists in the CDM community, from Austria and Germany to New York to Australia, got quite a lot working with tangible interfaces. At top, Michael Schieben and Christophe Stoll experimented with using soda bottles to control software like Future Audio Workshop’s lovely Circle. (Ableton Live works, too – as does any MIDI software.) As Precious Forever, these guys are responsible for some of the best UIs in music software, from FAW to recent Native Instruments designs, so it’s lovely to see them experimenting with this idea.

As you add more people to the mix, you get ideas you might otherwise never have imagined, from a game involving blocks of the Tokyo skyline to an interface built into floor toms.

We also got a lot of real-world data on what works, what needs work, and what causes trouble for beginners, which we’ll be documenting. (Adam and Martin from the Trackmate and reacTIVision projects, respectively, were both tuned in to see progress and provided lots of help – and are also collecting that data to improve their own documentation and libraries.) More commentary on all these side benefits, as well as a discussion with visitors from Argentina on the scene around the world, at Create Digital Motion.

Musical Resources

We also got some really helpful tips for working with the free, powerful, tri-platform synthesis tool SuperCollider:
Charles Martin wrote up an easy SC test script for receiving Trackmate messages (and also had the clever idea of using a floor tom)

And for connecting Trackmate to MIDI and working with Processing, lots of tips are available on Michael Schieben’s noisepages blog:

So, what’s next? You can join discussion and brainstorming for how to proceed, and how to get in on another hackday (formal or ongoing), even if you missed the first. Stop by the Tangible and Multi-Touch Interface group on noisepages:
Tangible + Multi-Touch noisepages Group

Our noisepages community is still in “alpha” state, but it’s usable – we’ve just fixed avatar uploading, which was the biggest problem. We’ll have more features, functionality, and improvements down the line, as well as more extensive documentation for how to get started. But if you’re a bleeding edge sort of person, join up free and give us some advice on what you’d like out of it.

I look forward to more work on these projects. Stay tuned for more, including some additional documentation (I’m developing some stuff around my own project).

As you can see, people have already begun playing with ideas for tangible interfaces. Oddly enough, two German gentlemen each named Michael (not aware of one another) have gotten a headstart, including the first experiment above in progress. We’ll be experimenting with new interfaces in New York and around the globe. (If that isn’t enough experimentation with new interfaces, the NIME conference – New Interfaces in Musical Expression – is happening now in Pittsburgh, and we expect reports back from that, too!) The event has also been featured on Boing Boing and MAKE.

Trackmate :: 5 ways to get started from adam kumpf on Vimeo.

The folks reading this site comprise an incredible worldwide community of creative musicians and technologists. So it’s always fantastic when we get to connect. Here’s our first experiment in doing just that with a one-day project starter to share. The theme: tangible interfaces.

The knob/potentiometer – when you get enough of them, plugged into the right things, in the hands of the right people – has given us some wonderful music. (Heck, see also the string.) Simple inventions + lots of people + creativity + experimentation = brilliant output.

Computer interfaces that make use of physical objects for input are nothing new. But what is new is easier tools for making use of them, plus emerging communities of people who are new to the idea bringing fresh ideas. So, as opposed to our usual behind-the-computer isolation, we’re going to get folks together for the first in a series of experiments in virtual, shared hacking.

June 6 (and in the days around it), we’ll have a shared online event, plus an in-person event in NYC at the wonderful New Work City, working with projects based on the simple-and-cheap, open-source Trackmate hardware+software, a tangible interface you can build for as little as US$50 in parts, including the essential webcam.

What you need: some cheap parts, a webcam, a computer, some objects to track, and some inclination – the tracking software is even already built for you.

What you can do: Apply stickers to track the physical objects, and turn any tangible real-world stuff into a musical interface. (Some coding or patching experience is recommended for connecting your interface to tools like Max or Pd or SuperCollider to make sounds, or for translating to MIDI for other tools.)

For musicians, I could imagine some really interesting possibilities. You can compose a wide variety of music and synthesized sound using nothing but a mouse as input; add a physical input with multiple points, and you lierally open more dimensions.

How to get involved:

• Building it: Parts + resources
• Join in: RSVP for the online shared event
• NYC: Some space left at the in-person event in NYC – RSVP required – plus a party in the evening. Other in-person events may get organized in other cities; stay tuned.

On Create Digital Motion I’ve written a more detailed explanation of the event, why we’re doing it, and how to get involved:

Global Hackdays: Experimenting with Cheap Tangible Interfaces, June 6

…and I’ve been adding to a blog on this project and future hackdays, which will be updated with more resources, ideas, tests, and tutorials leading up to, during, and after our first-ever global hackday:

http://hackday.noisepages.com/

By the way, apologies for completely botching our livestream of Handmade Music this week. Lesson learned: you need a reliably fast network to avoid total failure. New Work City is set up as an online-connected office, and they have a plenty-fast network, and if you follow me on Twitter I’ll be testing it the week of June 1. Readers have watched CDM experiment and learn by trial-and-error, though, and I always appreciate your support.

Also, this is not to be confused with Hack-A-Day, one of my all-time favorite places on the Internet. But let’s make every day a hackday.
