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.

Once upon a time, people made things from electronics. Boys, girls, laypeople made stuff. My Dad actually tinkered with Theremins growing up and subscribed to Popular Mechanics. Now, in an age of hyper-specialization, too many people assume that making sounds with geeky-looking, handmade electronics should be left to the pros. But give people some instruction and let them make some noise, and you might be surprised how eager people are to try something out. Noise making, it seems, is some sort of primeval human instinct.

So, it comes as little surprise that the wizards of Austin got lots of people into the act of electronic sonification. Led by Dr. Bleep, Eric Archer, and 8ms, they’ve kicked off the Texas iteration of Handmade Music Night, and send us the video to prove it.

There’s no reason you have to be left out of the fun, though – you can handmade some loud noises at home. Eric Archer has expanded the site for his freebie Mini Sound Rockers, the kit he used to get folks started at Handmade Music Austin:

Check out the video below to see them in action. And I think we should definitely have, in addition to the schematics, a step-by-step tutorial. The gang in Austin also promises some ready-to-buy kits coming soon, so stay tuned.

And for another video of the Mini Space Rockers circuit, here’s a terrific creation from Switzerland, as suggested by Eric in comments:

The work is by datenkrieger75, using both Eric’s circuit and a hacked Gakken SX-150 bassline.

It may be 2009, but you can still play electronic music as though you’re an invading alien visitor from the future. Just ask The Sonic Manipulator, an electronic musical performer and inventor, alias Claude Woodward. His musical creations range from warped radios to instruments derived from turntable scratches and Theremins. And then there are some instruments that seem to be sonic weapons. (Apologies to recent protesters in Pittsburgh.)

CDM reader Andrew Cordani caught Claude at the UK’s British Invention Show. Claude is apparently a Perth, Australia transplant, by way of Cambridge, though Andrew writes that he “has been known to travel about a bit (Mars, Venus, Jupiter, Alpha Centauri, Epsilon Indi, Teegarden’s star and further).”

Andrew describes Claude’s other creations:

Met at the British Invention Show (http://www.britishinventionshow.com/show/index.html), at Alexandra Palace (http://en.wikipedia.org/wiki/Alexandra_Palace)
(Organized by [MP3 player inventor] Kane Kramer – http://en.wikipedia.org/wiki/Kane_Kramer)

The Claude-a-tron – a sort of pre-wireless (i.e. wired) Theremin – and is “Way cool”

The Radiolian a lot of fun – Essentially triggerable (pre-recorded) radio samples – Used to switch-between radio programs (reminds me of http://www.neave.com/television/ )

The Greet-o-metre + The Transatron should be given out to all travellers, interstellar or not!

(My fave was the Rap Rod – which does for scratching what CDs did for vinyl. The Bash-a-tron was a close second, though)

Definitely check the Sonic Manipulator site for many, many more bizarre creations if the one at top doesn’t impress you. See a couple of my faves at bottom.

Fans of DIY, the whole event sounds fantastic! Thanks, Andrew, who can be found here (with his own futuristic creations):

Want to make a splash among the aficionados of digital sound? Releasing a software instrument emulating a broad collection of vintage digital synthesis chips from game and computer systems seems to do the trick. See my look at that software, and just as importantly, the chips that inspired it.

Within days of the release of Plogue’s Chipsounds, we have a couple of fair reviews of the new tool. Already got Chipsounds? Plogue’s David Viens has released screencasts showing you how to use it. Curious about other ways to explore vintage 8-bit sound? We’ve got that, too, in samples, hardware, and even SuperCollider code.

Reviews are in

Torley has an extensive video review – amazing stuff for something just days old – shown above. Gisle Martens Meyers has a review, too, on the blog Ugress. One complaint is that the plug-in is multi-timbral, rather than requiring different instances. In turn, automation is in the form of MIDI Control Changes, not parameters, since parameter automation really doesn’t deal with multi-timbral plug-ins. But all in all, you can get a lot from both reviews, plus a look at how the software works. There’s also a sense of where the software could go in future updates.

Plogue Chipsounds makes chiptune & video game sounds easy [Torley Lives]
Chipsounds Plugin Chip Sounds [Ugress]

The discussion of Chipsounds has also brought other efforts to resurrect vintage, 8-bit sounds.

Get Your Chip Fix

This is by no means comprehensive, but here are a few of the best goodies readers have pointed out in the last few days:

Free Samples: Little Scale, aka Sebastian Tomczak, has been busy. He’s added sample packs of his own, including a Friday release of the Commodore 64 SID. Add that to Sega Master System, Mega Drive, speech chip, and Atari POKEY and TIA. These are just samples, so rather than being a turn-key solution as Chipsounds is, they’re more of a construction set – though that could make them useful in other scenarios.

C64 SID Sample Pack [little-scale]

Go Hardware! And, in turn, if hardware fires you up more than software or samples, Sebastian has done some lovely work connecting the actual chips to MIDI interfaces.

And here’s the documentation on how to do it with the free and open hardware Arduino platform

Other hardware solutions:
A DIY TI SN76477N-based Voice Module, comprehensively documented (a heck of a lot fancier than the Arduino stuff I wanted to play around with)

SuperCollider Code: For SuperCollider fans, Fredrik Olofsson (aka RedFrik) has built emulations of vintage chips in the object-oriented sound coding language. That’s a doubly delicious thing: aside from allowing you to make 8-bit sounds in the free tool, looking at his emulations is a great way to discover more of what you can do with SuperCollider. You can continue in code the kind of elegant, minimal synthesis design work the early creators of the original chips did in hardware. (Thanks, Howard S and Morgan Packard for the tip!)

SC Code [and a lot of other great SC code there, too... bookmarked, downloaded.]

Video walkthroughs

I know quite a few readers did pick up Chipsounds, so you’ll be pleased to know – in case you missed this – that there are some video demos that walk you through how the tool works. This also gives a better idea of how the software itself functions, since I got distracted waxing rhapsodic about the chips!

As my piano teacher used to say to me, “that should keep you off the streets.”

Enjoy.

From Sarah and Lara Grant, we have a dress that makes music, with tube-like apparatus made of felt for connecting sound, modular fashion. From the raucous duo Great Tiger, we get a homebrewed arcade controller Ableton Live that mashes loops into dance music with a quick button push. Yep, it’s Handmade Music time again in New York tomorrow Thursday. If you’re anywhere in the area, come on down – and feel free to bring your own projects and/or expect some surprise technological appearances. If not, we’ve still got some MP3s, visuals, and how-to information to share.

If you do make it to Brooklyn, we can promise some behind-the-scenes demonstrations, noise, at least one live set, and free, ice-cold Colt 45s while they last.

Read on for event details, a preview of the projects, and videos and downloadable MP3s from Great Tiger.

Wearable Patch Cords in a Sonic Dress

Sound artists, inventors, and designer sisters Sarah and Lara Grant present an in-progress audiological fashion experiment involving patch cords made from felt. (I love the gorgeous conceptual drawing.) They’re working with a dancer to make this into a performance, and we get to see the work evolve before our eyes.

the title of the piece is ‘Audiotrails’, playing off of the word ‘entrails’, since as you’ll from the drawing attached, we are designing a dress that has several felted cords coming out from the gut which will act as patch cords. These patch cords connect to different parts of the garment to produce various noises and effects.

What we will be bringing is an example of our patch cord concept in the form of a felted swatch and a concept drawing of the final piece, which we have not completed, but hope to present either next month or the following at handmade music. We will be talking about our process and answering any questions based on that. Sarah and I had been envisioning our set up on a table in the smaller room, since had not been planning to perform and since our goal has been to show our progress of a project that would take a couple months to finish.

Here’s a look at one of the coils, a felted patch cable that can then become part of the garment:

Sarah Grant has also done fascinating research into what she calls “felted signal processing,” in which textiles can themselves become active sound elements.

Push the Button: DIY Arcade Controller for Ableton Live and the Button-Mashing Music of Great Tiger

That’s button mashing in a good way. Inspired by games, fast push-button moves and combos, and electronic music, the duo Great Tiger has built a custom rig for mashing samples in Ableton Live.

The custom arcade controller, looking like what happens when an 80s arcade cabinet and the monome have a love child, was featured on the DJ blog DJ TechTools. (Worth reading that article for lots more technical details from the duo.) This video by Great Tiger gives a behind-the-scenes look at how the hardware is used with Live and how it’s put together.

Here’s Great Tiger live in action at Brooklyn’s Red Star:

The grid is in. While the monome remains the standards bearer for hardware with grids of buttons on it, arrays of buttons are suddenly everywhere, in the commercial Akai APC40 and Novation Launchpad, and, from Livid Instruments, the Ohm64 and now the Block. I think it’s a real compliment to the monome’s creators – and the community that has authored ingenious open software for the monome – that there is this excitement around the design.

The latest entry is Livid’s Block, a compact, aluminum-and-wood controller that’s easy to carry and which weighs less than 3 pounds. It’s not a monome – it eschews the monome’s stringent minimalist design aesthetic and adds knobs on top, faders on the side. That layout has made the M-Audio Trigger Finger a blockbuster hit, so I think it could attract people who want more than just buttons. (That’s why choice is generally a good thing.) But just as importantly, the Block takes cues from the monome beyond the skin-deep. As with the Ohm64, Livid is working to open-source both the guts of the hardware and the software on the computer. The instruments are made by hand using sustainable materials and finishes, manufactured in Texas in their own shop rather than the lowest bidder overseas. The hardware itself encourages hacks and customization. These are principles championed by the monome’s Brian Crabtree and Kelli Cain, and they’re badly in need of some company. Livid, like those monome creators, is a handful of individuals rather then a big company, but they give us new hardware that embodies sustainability, openness, and local production – and that makes the monome and its principles stronger. (Livid has been crafting performance hardware and Max patches for many years.) And while this bus-powered USB MIDI device doesn’t yet support (OSC) OpenSoundControl, that could come – without sacrificing conventional MIDI connections to outboard gear when you don’t have the computer connected. (Clarification: as with the Ohm64, OSC support is not yet available but should be possible. Stay tuned.)

Basic specs:

• 8×8 backlit keypad with corresponding knobs, function buttons, and faders
• Square layout that can be used at any rotation (so the USB port lies where you want it)
• Runs a suite of apps built in Max/MSP from Livid – including a sampler, synth, sequencer
• blockEditor for customizing layouts, lights
• US$399, available November 1

I’m interested in more open software, so I’m working on making an editor in Java and would love to hear what else people might want. (SuperCollider looper? Pd algorithmic grid controller? Processing library?) These I hope to make work both with the Livid hardware’s added faders and knobs, and the monome’s more minimal design. Of course, OSC will be terrific for computer applications if that comes to pass, but I love the idea of gear that can also talk to MIDI hardware.

I really like Novation’s Launchpad, but for a little more money, you get a beautiful case, additional controls, and added flexibility, all in gear handcrafted by the maker and with an open approach to hardware and software. Without getting into a debate over the merits one way or another, consider this: you can choose. We didn’t use to have these kinds of choices in music hardware. The fact that we do now – not only the ability to choose the nameplate, but the very philosophy behind the device’s manufacture – I think can benefit everyone, users and manufacturers alike. It opens up the entire music tech industry to new ideas and new variety.

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 Project:

“Play Box” is is a User Interface for Natural User Interaction.
? allows multi-touch and object recognition (TUIO marker)
? hovering is also possible
? 22 ” TFT display , 1680 x 1050 pixel
? robust
? plug`n play

“Play Live” is a dedicated multitouch controller surface for Ableton Live.

- GUI Elements support multi-touch interaction
- easy to setup , just load the “Play” Control Surface
- you need no controller assignment
- you can control 32 tracks and 127 scenes, that are 4064 clips
- track controls are mute, solo, record, send1, send2, pan, level
- scene feedback name and state
- clip feedback color, name and state
- Transport control
- 2 Returns
- Master
- support bidirectional communication
- display track level meter, name

The whole app is coded in python.
- use Python Ableton Live API
- and libavg www.libavg.de for the GUI and Trackingengine
- PyPortMidi receive/send Midi Messages

“Play Live” Future plans:
- FX View per Track
- subpage for abstract clip controlling

I tested it with my mac book pro, “Play Live” and “Ableton Live” is running at the same machine. It should work on all platforms (Windows, Linux, Mac OS X). That Project started with my Diploma Thesis in Applied Computer Science 1 year ago.

Everything is coded and built by myself. The GUI – elements has been designed by Gösta Wellmer.

In this work, I created a GUI-Controller Library which allow me to Develop very rapidly Multitouch Interfaces for other Audio Environments.
More Apps coming soon ;-)

I [plan] to sell the” Play Box” and Apps like “Play Live” if anyone is interested.
The price is yet not specified.

That`s not my first multitouch Interface. 2 Years ago I created forfour – http://forfour.hi-pi.de/
- used PD, Processing, Reactivision and OGRE.
But the “Play Box” is another level;-)

I hope to have video to share soon – and yeah, it’s time to plan another visit to Berlin.

Autonomous bassline generators? Wireless, modular, infrared sync? Tiny drum machines networking together? Welcome to Texas, and the minds of Eric Archer, Bleep Labs, 4ms Pedals, the Church of the Friendly Ghost, and Andromeda Space Rockers.

One look at a floor full of blinking circuits, and most ladies and gentleman might assume they’ve stumbled upon some alien technology. “Imagine the things we could learn from this civilization – advancements far beyond our own,” as the stock line from sci fi goes. “Man and woman are not meant to learn such things. You’re meddling in things beyond your comprehension.”

In other words, you couldn’t build something like this, right?

Or could you?

In Austin, Texas, Eric, Dann, and Dr. Bleep are launching a new Handmade Music series, kicking it off with kits and classes so that anyone – including beginners – can start building stuff. For the 101 crowd, there’s a free beginner class even if you’ve never touched a soldering iron, so you can build your own analog drum. “I’m no n00b,” you say, “impress me.” Sure – the “upper division” gets to talk more advanced synth design and walks through the full-blown modular, networkable kit.

At the end of it all is an open jam and featured performance.

If you’re anywhere near Austin, Texas – or can find a bargain plane fare – you’ll want to clear your calendar for October 18!

Full Event Details, October 18 Handmade Music in Austin [Handmade Music @noisepages]

That’s just the first of more events to come, so stay glued to the Handmade Music site for events in Austin, New York, Portugal, Germany, and beyond.

“That’s right / you’re not from Texas / Texas wants you anyway.” For those of us in New York, Lisbon, Rio, Sydney, and Jakarta, there’s still hope. The kits will be online, and I”m looking at ways of putting together a full Handmade Music curriculum of projects online for all of us on the site we’re developing this fall, noisepages – ideas welcome.

I certainly didn’t expect to get deep into these geekier topics in high school while I was busily trying to fail Calculus and screw up science lab results in ways that baffled my teachers. But it’s a glorious age we live in, in which we get to assimilate alien technology as our own. Stay tuned.

four tiny drum machines from ALH84001 on Vimeo.

Cybernetics is poised to make a comeback. The theory is, everything from electronic circuits to plants and animals can be understood in terms of feedback loops, as organisms – mechanical or organic – respond to input from their surroundings. The father of modern cybernetics, MIT mathematician Norbert Weiner, was inspired by working on the guidance systems of missiles. His writing was picked up Louis and Bebe Barron, informing their organism-like sonic circuits, as used in the film Forbidden Planet. The word cybernetic itself comes from Plato. Plato was talking about human self-governance. But designed with cybernetic ideas in mind, technology, too, becomes self-governing and autonomous – and the sonic circuits, too.

Young designers like Eric Archer are to me the newest continuation of work like the Barrons’. Inside his lab, Eric and others are creating hardware that behaves like intelligent life. In the video at top, four tiny drum machines, equipped with insect-like brains and reflexes, network together wirelessly over infrared, responding to light by way of photocells. These tiny devices form a colonial consciousness.

Eric may be a mad scientist, but he isn’t keeping his work secret or proprietary. He’s sharing the tools, sharing his methods, and with a whole growing crew of sonic DIYers in Austin, Texas, inviting anyone to join the revolution under the banner of the Handmade Music series. (More on the upcoming event shortly.) If you’re not from Texas, a lot of this documentation is also appearing online.

Here are more of the creations, plus the simple but powerful circuit that makes it all happen.

And yes, there’s a lot of potential to wireless IR sync.

The drums have names:

Drum Machines (Eric Archer)
ASR mk I “pops”: two analog damped sine oscillators with photocell pitch control, 16 presets
ASR mk II “snappy”: analog white noise, photocell controlled filter, envelope + VCA, 16 presets
ASR mk III “twiki”: photocell tuned analog osc, photocell tuned LPF, envelope + VCA, programmable
ASR mk IV “boomer”: analog damped sine oscillator, long decay, photocell pitch envelope, programmable

But drum machines are just the beginning of what could eventually be wirelessly synced. First up, this autonomous bassline generator, created by 4ms Pedals

The Autonomous Bassline Generator creates deterministic bassline patterns in a sci-fi retro sound by generating melodies on the fly, based on a knob. It’s just an AVR (attiny44) chip doing all the work, plus an opamp to act as the filter (photocell). The blue button is Tap Tempo, or if you hold it down for 1 second, it syncs up to the pulses on the IR receiver (this lets you beat-sync multiple Andromeda Space Rocker modules). The red button lets you edit a single note in the melody. Pulse-width modulation is currently pre-set to a certain envelope, but that will become user-controllable soon!

Part of the “Andromeda Space Rockers” series of modules, see www.ericarcher.net for drum modules.

The 6-pin header board dangling to the right is an ISP header. Totally hackable!

“Ah,” you say. “But I have computers and things. I don’t just want a bunch of little drum machines running around my studio like so many electronic beetles while I furiously tap my tap tempo in Ableton. Can’t I sync thing up?”

Yes. Yes, you can. There’s already a MIDI-to-IR prototype in the works.

Four analog drum machines are synchronized with a desktop computer running Logic. Logic is playing a loop with TR808 samples. MIDI timecode from Logic is converted to IR Sync with a PIC microcontroller. The PIC flashes an infrared LED, providing wireless clock to a chain of analog drum modules. Each drum module has an onboard sequencer, analog sound generator, and IR Sync repeater. At the end of the video, the tempo is increased to almost 3000 BPM. In a separate test, the system played OK at 1000 BPM. Of course this tempo is ridiculous but it is a nice “torture test” of Nathan’s PIC code.

PIC stuff: Nathan Wooster
drum machines: Eric Archer

Our friends at Bleep Labs also have projects in the works.

Eric and 4ms have contributed the circuits at the heart of this.

This simple circuit handles infrared clock networking. (Click for the full circuit.) I’m assuming you know how to read this; we may have to put together an actual how-to tutorial for those new to electronics, too.

And 4ms has a version for interfacing with microcontrollers.

The Barrons would be proud.

Austrian Composer Peter Ablinger has transformed a child speaking so that it can be played as MIDI events on a mechanically-controlled piano, making the piano a kind of speech speaker. Via Matrixsynth, the readers at Hack a Day get fairly involved with how this may be working.

It seems not quite accurate to describe this as vocoding in the strictest sense, so much as a simple transformation to a (much) lower frequency resolution – that is, the 88 keys of the piano. Ablinger, for his part, describes the events as “pixels.” It’s pretty extraordinary that without a bandpass filter, you get something approximating the noisy sibilance of the speech, but this seems to be the result of having lots of events (that is, lots of resolution in terms of time). Edit: Listening again, the short answer to how you can hear so much of the voice through the piano seems to be, you can’t; the original is almost certainly mixed in. It’s nonetheless an interesting effect, and I’d like to hear the piano on its own. In other words, the basic process is, 1) convert the sound spectrum of the recorded voice to a series of MIDI events, and 2) play back the translated MIDI file. You can see that the MIDI playback is accomplished with Pd (Pure Data) running on a Windows Linux/KDE netbook, though it’s not clear what was used to do the original conversion. (The screen shot with side-by-side audio and MIDI appears as though it may be for demonstration purposes, only.)

Correction: The work is absolutely done in custom software developed by the composer in Pd (Pure Data). It’s an ideal tool for the job, and free and open source. I wouldn’t dare try to replicate the results here, but this is fantastic inspiration for playing with sound in Pd.

One Windows tool that’s capable of the job is TS Audiotomidi, as observed by Hack a Day spacecoyote. Whether or not that’s what’s at work here – and it may well be – that utility is itself interesting. Edit: Yeah, far more likely the whole thing was done in Pd. And Pd should be up to the task.

TS-AudioToMIDI

Of course, this is to say nothing of the lovely work done on the mechanical piano. It’s a beautiful piece. Here’s hoping some government bureaucrats got the message of the declaration. Now, we just need a chorus of something really loud – say a thousand trumpets – shouting out the Universal Declaration of Human Rights.
