MIDI control of analog devices from Michael Una on Vimeo.

John at HighlyLiquid has been busy this year- he’s got a new kit out and one in the works that really step up the game. You may be familiar with his previous kits, which add MIDI control to Speak & Spell, Atari 2600, or pretty much every Casio. HighlyLiquid also stocks more open-ended kits which can add MIDI control to pretty much anything- I used one in my MAKE Magazine article last year to build a drum-playing robot.

The new MD24 falls into the latter category. It takes a MIDI input and gives you 24 discrete +5V outputs that can be used to drive relays, transistors, or servo motors. Functionally, the MD24 is similar to HighlyLiquid’s MSA-T or MSA-R kits, except that you now have 24 outputs instead of just 8- a significant improvement.

Certainly, people with a lot of time on their hands will say “I can do that myself with Arduino, running MIDI through the USB-to-serial converter, and I’ll build a custom Max/MSP patch to control the parameters.” Sure you can, but personally I prefer to spend only as much time as it takes to get my musical systems up and running, instead devoting my time to actually making music and practicing my live set. If you are like me and love DIY stuff, but also don’t want to spend 6 months programming your own ATMEGA chips, then I recommend you consider this type of solution.

I found the kit very easy to assemble. The board is laid out with a decent amount of space between the components and is clearly labeled. The online instructions were very thorough and identified any potential problems. I was able to assemble the kit in about 40 minutes and I was able to hook the MD24 up to my handmade sequencer synth very quickly. It all worked on the first try. (Disclosure: I’ve built one of these kits before and pretty much knew what I was doing, but I didn’t find it all that difficult the first time I did it either)

I made a little video to demonstrate the system in action, which works a lot better than trying to describe it with text. (See top)

My conclusion: The HighlyLiquid MD24 MIDI Decoder kit is a very affordable, powerful solution for all your analog sequencing and control needs. My imagination was really sparked by this one, and the potential applications are immense. HighlyLiquid bridges the gap between the analog and digital worlds very elegantly and with a minimum of time and fuss- 100% win.

And, a teaser: There’s a DIY MIDI controller kit in the works which looks totally awesome. I hope it’s released soon because I got all kinds of plans for it.

If you’re in the New York area, tomorrow night we have another noise-making get-together at the lovely 3rd Ward. The event is free, and we have free Colt 45.

Amanda Ervin is the featured guest this month; see one of her circuits above. Her designs are intended to be something that other folks can make, so they could be an excellent starting point for the project you’re dreaming of. (And once you get sequenced events down, of course, you can assign them to whatever sounds or visuals you like.)

Thursday, September 17
7:30 – 10:30 pm
FREE
3rd Ward in East Williamsburg; Directions
With the support of Etsy.com, Make Magazine, and XLR8R.com

Full details:

And on Facebook:
Handmade Music Night

Nice blurb on myopenbar.com

I’ve given up on live streaming from the event because we can’t get a reliable connection, but we will have documentation for CDM on the projects afterward.

Amanda Ervin makes elegant noise-making apparatuses from simple circuits, and is able to share that process with her students (see her classes among 3rd Ward’s Circuits lineup). She’s going to show off some of her latest creations at the open showcase of Handmade Music Brooklyn, our monthly party + science fair + musical performance + ruckus. (More details soon on Handmade Music events that are springing up worldwide, thanks to the hard work and creativity of the DIY music community!)

What really impresses me about these projects is that Amanda has made both the project and the curriculum – that is, she can teach you to make these, too! It’s often easier to make something for yourself alone than it is to make it reproducible, so I do admire that in a design.

If you’re in the New York area, you can catch the event free, Thursday evening September 17. (Directions) If not, we’re working with 3rd Ward on ways to translate the educational experience online.

Here’s a musical excerpt from Amanda, as well:

WalkSX from Gijs on Vimeo.

As the Sony Walkman turns 30, many of the mobile cassette’s fans wax nostalgic. But it takes Gijs Gieskes to wire up a new Rube Goldberg-style musical instrument based on the Walkman’s simple tape playback.

Follow along carefully through the signal flow of this unusual instrument:

1. The Walkman has audio on the tape itself, sampled from a Roland TR-808 drum machine.

2. Because a compact cassette has two tracks (left and right, for stereo), one track is dedicated to the drums, another to the rim shot.

3. The rim shot track is fed as a mono audio input to an Arduino (the open-source microcontroller platform). The Arduino responds to the audio level, so each time a rim shot hit occurs, it ….

4. …sends a sequence event to the Gakken SX-150. That means that you can adjust the speed of the whole contraption by…

5. …adjusting the speed of the tape. (Bless you, analog playback!)

It takes Gijs to think that way somehow: put together, these elements are actually fairly simple, but strikingly effective. Fortunately, if this does inspire new ideas, Gijs has posted all his Arduino code, so you can check this out and try something yourself.

A $50 synth that makes neat noises is fun. But a $50 synth that has a proper housing, audio jacks, and can be MIDI controlled — that’s a whole lot better. So readers were wowed last week as we saw the work MrBook did with his Gakken SX-150.

Now, by popular demand, MrBook shares his techniques with specs, instructions, and code. This isn’t a bad project to get started with if you’ve been thinking of doing something on these lines.

The basic ingredients and process:

• Find the connections on the synth for audio and control, using contact points on the board
• Build a simple circuit that adds MIDI input (control) and audio output – schematic on his site. It’s not a tough circuit at all — this could be fun soldering practice.
• Add the Arduino, the open source, dirt-cheap, accessible microcontroller project board, and some code MrBook has written for you.

That should be fun even for relative newcomers – provided you have basic soldering chops. If you want to get more advanced, there’s room to modify the Arduino code to do fun stuff, or, as MrBook is doing, add a standalone Arduino sequencer or the like to drive your synth in hardware alone. (While I’m still on a crusade to do OSC for stuff that talks to computers, I think MIDI should absolutely be used for what it’s good add – connecting hardware.)

You can also have some fun with the casing. (Someone needs to mod the drab colors on the Gakken, too, I think.)

If you do a project and document it, do let us know! And we’ll be watching for more from MrBook.

You can get your SX-150 kit from our good friends at MAKE. (Nope, I’m not getting any cash for saying that. Hmmm… okay, I need an affiliate account, don’t I? Make?)

Elly Jessop and VAMP at the Maker Faire from The Amazing Rolo on Vimeo.

Yann Seznec aka The Amazing Rolo brings CDM his coverage of music tech at the Maker Faire in three episodes today.

Continuing the tradition of computer-augmented vocal performance and interactive gloves, Elena “Elly” Jessop shows off her VAMP system at Maker Faire. Elly is a Masters student at the MIT Media Lab’s Opera of the Future research group, headed by Todd Machover. Interestingly, Elly’s background is in conventional theater, including stage and costume design and choreography.

http://web.media.mit.edu/~ejessop/

VAMP stands for “Vocal Augmentation and Manipulation Prosthesis.” What’s really nice in this demo is that the results sound like more than just effects – they begin to become real augmentation, setting up a complex relationship between the vocalist and the sounds that come out.

It’ll be great to see your work evolve over time, Elly, as you fuse that experience. (And I know what a challenge can be, as I’m still working on fusions of my own, having likewise come from various non-digital backgrounds… heck, I made my way through puppetry class at Sarah Lawrence, even. It’s a lifetime-scale commitment.)

For more on data gloves and such: composer, computer scientist, and futurist Jaron Lanier did lots of seminal thinking about these ideas leading back to the 80s. And you can find some extraordinary work from “augmented vocalists” like Laetitia Sonami and Pamela Z. Here’s a terrific 2006 interview by Sua Constabile for Cycling ‘74 with Laetitia:

Barry Threw demos the K-Bow at Maker Faire from The Amazing Rolo on Vimeo.

Yann Seznec aka The Amazing Rolo brings CDM his coverage of
music tech at the Maker Faire in three episodes today.

As long as there have been computers, violinists have looked for ways of extending the nuances of their physical performance into the digital realm. (Us keyboardists have it easy – we’re used to pressing an array of levers, and a lot of the gestures we make are, arguably, superfluous.) Many of these concepts return to the idea of the bow.

The K-Bow by Keith McMillen Instruments is a Bluetooth-enabled bow with sensors that read bow angle, length, acceleration, grip pressure, and even hair tension. It’s accompanied by software developed in Max/MSP. The bow itself is one of those “if you have to ask, you can’t afford it situations,” at US$4000-5000 retail, though they claim the bow itself – specially-designed kevlar and carbon graphite, anyone? – can compete with more expensive bows even before you add in the sensors.

http://www.keithmcmillen.com/kbow/index.html

In the video at top, developer Barry Threw of Keith McMillen Instruments demonstrates the K-Bow.

Here’s what you get out of the software screen:

Barry has also written up a visit to the STEIM research center and work with sensor bow pioneer Jon Rose.

And yes, you can rock out hard with this thing:

I know what you’re thinking – you could also just hook your violin into a pickup and some distortion pedals. I think it’s really the experience of playing it that changes, though I’m just guessing, since I’m not a string player.

Previous research projects:

Jon Rose’s own Hyperstring project (warning: loud hyperviolin audio auto-plays, and I don’t see any mute button!)

The Augmented Violin project at IRCAM: see Emmanuel Flety’s development blog, IRCAM project page and references

And that’s by no means a complete list, of course.

Who are the people in your DIY music neighborhood?

Well, quite a few of the DIYers here on Planet Earth are converging this week in New York. Lover of circuit bending, creative electronics, and DIY music hardware are gathering for the massive Bent Festival in Manhattan, complete with performances, workshops, and a book launch. And we’ve got a special edition planned of Handmade Music featuring several artists from Bent, too, in our monthly free event. For the rest of the planet, I hope to share some of these goodies well beyond the borders of the five boroughs.

To give you a taste of the kind of work we’re doing, check out the videos here of Chiptune Marching Band, getting kids making noisy circuits for the first time and the fantastic electronic workings of Peter Edwards’ brain, plus NPR radio coverage of Ranjit Bhatnagar’s hand-crafted “Instrument a Day.”

For more on handmade music and Ranjit’s brilliant, self-motivated hand-crafted Instrument a Day project, NPR did a fantastic piece on All Things Considered:

An Instrument A Day, Crafted By Hand [audio, interviews, and sound examples of some wild and wonderful instruments]

Interested in experimenting with MIDI, minus the wires? Why not try a DIY hack yourself? Limor Fried aka Lady Ada of Adafruit Industries has posted a detailed tutorial on transmitting MIDI over the inexpensive and relatively friendly XBee wireless module.

It’s a bit of a hack – you force the XBee to communicate at MIDI baud rate, and on Windows, at least, you have to fool the OS into using MIDI’s non-standard baud rate for serial communications. But it seems to work. That’s where you come in: Limor’s got some folks testing this, but we could use some additional real-world tests and a “port” of the instructions to Mac OS and Linux. (I’ll be testing, too, once I get my hands on some spare XBees.)

Tutorial: Using XBees to create a wireless bi-directional MIDI link [ladyada.net/make]

HOW TO – Using XBees to create a wireless bi-directional MIDI link [adafruit blog]

Ingredient list:

• XBee module
• Adafruit’s own handy XBee Adapter Kit (an adapter board that makes it easier to add the wireless module to your own projects)
• Parts for making the MIDI adapter: MIDI connectors, optocoupler, hex inverter
• A computer (Limor runs Windows, but any OS should work)
• Some MIDI gear (see: hardware manufactured from the mid-1980s to now)

How does this compare to commercially-available wireless MIDI adapters? Honestly, I have no idea – that’s where we could use some real-world tests. (Yeah, I know – I’m really helpful. But then, there’s still a compelling argument for wires in many situations.) My guess is, if you’re serious about wireless MIDI, you may want to consider other alternatives.

If you’re serious about wireless, in fact, you may want to look beyond MIDI. Brian Kerr, who brought his own wireless controller to a recent Handmade Music night, chose OpenSoundControl after unsuccessfully testing MIDI. The problem with OSC, of course, is that you really need MIDI on the other end for almost all hardware (like Limor’s own x0xb0x 303 clone). OSC is a better choice if you’re building your own project – you can always convert back to MIDI on the other end, but you have the convenience of OSC over wireless and can use OSC natively with software that supports it. (Visual software, tools like Max, Processing, and SuperCollider, and – I really do believe – soon, music software will work.)

But then again, this is a fantastic way to experiment with the XBee and to try some fun stuff with MIDI gear you’ve already got hanging around – and may be just fine for some applications. I’m eager to hear how it goes. More on wireless control and projects soon – stay tuned. Thanks for the great work on this, Limor!

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).
