Clean is overrated. If you’re ready for a little digital dirt in your synth life, powered by the open-source Arduino hardware, Marc Nostromo’s Squealer is for you. Built atop the wonderful, Arduino-based Pocket Piano kit by Critter and Guitari, it’s a full-blown, simple, digitally-gritty synthesis engine.
You get a monosynth, some fixed waveforms, a resonant filter, decay, and some aliasing tricks for extra grit. The big news: the Arduino Piano Squealer is now under a GPL license.
Novation’s Launchpad, its affordable (< $200) "grid" controller, may have a big Ableton logo on it. But underneath, it's just a MIDI controller. Bi-colored LEDs, containing a red and green element for red, green, and amber output (amber = red+green), can be triggered using simple MIDI note and control messages. That means, whether you're looking forward to Max for Live or you're sequencing in a tracker or writing Processing sketches, you can use the Launchpad just like any other MIDI controller.
One of the things I thought was a major demerit for Akai was the fact that they failed to ship a MIDI implementation for the Akai APC40. MIDI implementations are the charts of MIDI messages we've had since the very first MIDI devices came out in the 80s. They're usually printed in the back pages of the manual, and even the cheapest gear has often had one.
Score: Novation 1, Akai 0. Novation has done the MIDI documentation, and then some. Its MIDI “Programmers Reference” is out even before the official Launchpad ship date. And rather than just doing a MIDI chart and assuming people know how to read it, they’ve taken the care to fully explain the way MIDI messages work, how to calculate the right messages, and how to really use this. Experts will have all the information they need, but newcomers will also find they can spend a little time and learn how to do what they want.
It’s listed as “for Max/MSP programmers,” but anyone using MIDI will want to have a look; that’s obviously relevant to far more than just Max. (In fact, there’s not a single mention of anything specific to Max in the document.)
What might people do with stuff like this? Well, as of just four hours ago, Matt DiFonzo lets us know he’s written a simple monome emulator. It’s even got a clever name:
There’s some bad news mixed with the good. Even with something as simple as a grid of buttons, MIDI isn’t as friendly as it could be. I still would like to have a MIDI editor for the Launchpad so you can reassign buttons if you like — that’s a feature, incidentally, available on rival Ohm and Block hardware from Livid Instruments. Also, the documentation reveals that Launchpad uses “a low-speed version of USB,” which runs at a maximum of 400 messages per second, thus taking 200 milliseconds to update a Launchpad’s LEDs. (There are some workarounds, but they’re … more work. Clarification: Once you double up messages, though, you can get this to a more acceptable gap, and that’s for updating all the LEDs, not the latency of input messages.)
As computer music practice – part composition, part instrumental play – spreads, the idea of software interface as performance tool is becoming second nature. Putting those opposable thumbs and sensitive fingertips to work, multitouch controllers are growing in number, variety, and sophistication. Berlin-based artist Marco Kuhn shows off his beautiful creation, the PlayBox multitouch hardware, and its first app, PlayLive. That first software focuses on Ableton Live performance, but Live could be just the beginning – Marco has worked with Pd in the past and promises other apps to come. He’s interested in selling this device in the future, and he shares with us the tools he used to create this work for those of you doing development along similar lines.
The Pico model may lack the impressive array of keys on the flagship Alpha, but when it ships next month it’ll cost well under a grand. And even the Pico promises high-resolution touch, velocity-sensitive keys that you can “bend” as well as press, and high-resolution breath input.
The “space bassoon” Eigenharp seems to have landed from another planet. Today, I’ve got good news: it’s bringing alien gifts with it. By next year, both the software and the high-performance protocol the instrument uses will be open source. Taken together with other advancements in the open source community and with protocols like OSC, that could mean we’re at the vanguard of a golden age for more open, more intelligent, more expressive digital instruments.
Genuinely new music controllers made available commercially don’t come along very often. So this week’s news of a strange but wonderful-looking instrument shaped like a bassoon with customizable key controls turned many heads. With high-resolution, high-frequency data and reliance on the computer for everything from sound generation to mapping the keys to different tunings, the computer connection matters. Eigenharp’s chairman, John Lambert, sets the record straight for CDM on the software, the way it talks to your computer and other gear, and how open the tools and protocol will be.
I’ll be talking more with John next week, but I want to bring you this news now. Part of blogging means that you don’t hold back – you share that first reaction and then learn more. I’m pleased to say I was dead wrong on the Eigenharp. What looked on the spec sheet like MIDI-only communication and proprietary software turns out to be just the opposite. Sometimes, being wrong is great. Here are all the details:
Part of the beauty of the iPhone from its launch date was the notion of a Mac you could fit in the palm of your hand. That makes it ironic that, for so many developers, mobile platforms in general have turned into a way to fragment software, to make it run fewer places instead of more. There’s something to be said for designing to a specific mobile device, but on the other hand, how many developers would want to restrict where their creations run? And particularly in music, isn’t the appeal of mobile creation the ability to have your tools work in more places? Maybe targeting just one gadget is the right choice for a given tool, but it shouldn’t be the only choice.
On the iPhone, the application Thump has plenty in common with a range of mobile music making tools. It’s simple but fun, a groove box with sequencing, subtractive synths, drums, and a set of basic effects, plus the ability to load your own samples and export songs.
Thump also demonstrates how simplifying sonic capabilities can produce musically-beautiful results, by focusing on the essentials and creating something with personality. Here’s a track by its creator showing off its sounds: thump soundreel by mazbox
What might not be immediately apparent is that under the hood, Thump makes use of the open source environment openFrameworks. As a result, the same code runs on iPhone, Mac, and Windows, as well as Linux. (It’s not distributed for Linux, but it could be. Hint, hint.) Creator Marek Bereza gives back, too – he ported the openFrameworks audio library to the iPhone, where it’s available to anyone.
Updated Marek notes in comments just what this means. The video below is, essentially, the same app. In place of the iPod screen, he has used a massive lattice of physical controls. A separate installation at the same show used a large touchscreen and simplified interface. And this really demonstrates what cross-platform means. Guy Kawasaki in the 80s mocked “ports” as a cheap wine. The idea is not to simply dump your code on a different platform and hope for the best – in fact, in this case, the changes from one platform to another were radical. The key is maximizing what’s essential, what really is not specific to a single device.
