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?)

The art of music is as expressive an art as you can find, so why shouldn’t the objects we use to make music be equally personal and creative? That’s the question we ask regularly on CDM, so we’re pleased to be sponsoring a contest with our friends at Instructables, along with the good people of Bleep Labs and custom speaker maker Zalytron.

Instructables, of course, are a site that let you share step-by-step instructions for making stuff. Far from keeping you art secret, they let you claim bragging rights for brilliant creations by letting you share how you’ve made them — and how other folks can do the same. It says that making things doesn’t have to be about something you’ve got that no one else does, but on the contrary, that value can actually come from other people doing the same thing. I got to meet the co-founders on the panel we gave at the OFFF Festival in Lisbon – really terrific folks.

For the Art of Sound Contest, anything’s game – homemade and modded instruments, electronics, circuit bending, speakers, controllers, the lot – even visuals. At the risk of influencing the voting, there’s already a musical light show, on the visual end, a sequencer (seen at top), an Arduino trumpet, and, yes, Spock lovers, even a Vulcan Lyre.

By the way, if you document stuff on Instructables, you can now embed the steps, as seen below. So that means you can make your own page on our in-alpha-testing noisepages community site and add additional details in blog form.

Check out the latest and most popular entries on the contest page:

And, of course, even if you don’t enter, you’ll have lots of things to try making. If you do want to enter, you have until July 26. Stay tuned to CDM as we keep track of the contest and the projects – even if you can’t enter, I promise we’ll have some goodies to share. And, of course, there’s an instructables for how to enter:

How To Enter the Art of Sound Contest – More DIY How To Projects

I’m especially fond of these speaker creatures. Mustache? Monocle? Check. And, hey, even if you lose, there’s an Instructables to teach you to make your own.

Too cute…

Updated: It seems Instructables has gone to a new pricing model. I’m still getting all the details as this is a recent announcement. I realize this may be cause for concern for some of our readers. Suffice to say, I understand that bandwidth-consuming sites aren’t free to run as a publisher myself, but I also understand creators being concerned about specific restrictions – particularly in regards to content they’ve created. It does appear that the “free” accounts are functional; I’m just unclear, for instance, on the “secondary images” – what sizes you have access to, etc. Stay tuned.

Ableton Live enthusiasts, you take very seriously what gear you plug into your laptop sets. We’ve seen painstakingly-created DIY controllers like the arcade button hardware below, and bizarre oddities like calculators and arcade cabinets and blenders and Osterizers (above). So, in celebration of New York installment of the Dubspot Ableton Live 8 Tour, Saturday, June 27, we’re going to get together in a fantastic space and have a little Live party. And we want to see what controllers you’ve made.

If you’re coming to town for the Live Tour or are in the New York area, we’d love for you to show some of your creations. Built or customized your own controller? Got your Wii remotes and webcams running your Live set? Built your own special Reaktor / Pd / Max / Python creation to customize your Live performance? Invented some hardware that works with Live? We’d love to see it. It’s a week that includes some of the most skilled Live minds in the planet presenting, plus celebrity appearances by the likes of Richie Hawtin, Scientist, and others. So we expect that even though this is last-minute, this could be a fun chance to get together.

If you’re interested, just sign up below or head directly to the Google Docs form. This is an informal, relaxed venue with drinks and finger foods. (Check out the recent New York Magazine write-up.) The idea is to bring along some headphones or small speakers and show things off in the catacomb-like former stables (and former sex club) nooks of this fantastic bar, meet up, relax, and get to know each other. We’ll also feature a live performance or two; if interested, let us know what your stuff sounds like.

The event will be open to the public; stay tuned for more details on this and the event itself.

And if you want to learn how to use controllers intelligently with Ableton Live – from the cheap and accessible to the weird – I’ll be teaching a workshop at Dubspot on Sunday 6/28.

Sign up, creative folks:

MUTEK this year looks to be a tremendous few days of audiovisual performance and art. To get in the mood one day early, we’re working with our friends at New York’s eclectic monthly live electronic party to host a special Montreal edition of Warper. It’s a convergence of New York and Montreal artists (full lineup below), running a full twelve hours. It’ll be totally free (donations welcome), with a cash bar available all day and night.

A big thanks to Jazz Mutant, makers of the OSC-driven, multi-touch controllers Lemur and Dexter, for their support.

I’ll be covering both the pre-party and MUTEK and its artists all week long, along with Greg Smith for Rhizome, so stay tuned to CDM for stories, video, and sound.

Meet up in the open lab: At 2pm, we’ll have an open music and visual technological laboratory, a la our Handmade Music series. Artists will bring their rigs, and original hardware and software creations to share what they’ve made and how they play. Confirmed for the lab:

• Multitouch and Open Music Tools: Nathanaël Lécaudé and Eric Andrade will show their open source multitouch table PyMT (built in Python), which works with Max/MSP for sound generation, plus the TamTam musical software suite, an educational music suite powered by Csound that runs on the OLPC (and other platforms), created at the University of Montreal by Jean Piché and his team.
• A Chipsound Premiere: David Viens of Plogue will be on-hand to talk about Plogue’s “chipsound” software instruments, as scooped on CDM – and I hope David brings along some Bidule creations, as well.
• Guitar video instruments: Matt Dickey is bringing his guitar-video rig, powered by Jitter, which allows audience members to conduct his playing and control visuals and … you’ll just have to come see it to fully understand. (See also his guitar-controlled generative visual experiments.)

Bring your cool rigs + projects: If you’d like to join in on the lab and you’ll be in the Montreal area, just fill out this form to let us know what to expect. (We have 1-2 projectors, a PA, and tables; bring extra amps and cables if you can.)

Lemur multi-touch demo: At 5pm, Brooklyn musician Nick Shelestak (White Badger) will demonstrate how he integrates the Lemur multi-touch hardware controller in the studio and on stage using Ableton Live, along with a few other special features unique to the Lemur.

Audiovisual lineup: At 6pm, we get into fully live audio and visuals from our friends in Montreal and in town from New York. It’s a packed lineup – see the full details below. (The Cougarettes and I will each be doing simultaneous audio and visuals…)

The Gamelatron at the Chelsea Museaum Teaser

Handmade Music hits Brooklyn again Thursday night with a terrific lineup:

• Robotic gamelan instruments with the Gamelatron, created by Zemi17 and the League of Electronic Musical Urban Robots (LEMUR) – check the video above!
• Rescued PDAs and iPods making music, with the Linux-powered ReWare project (which even allows you to run Pd on an old iPod), by Hans-Christoph Steiner – expect a box full of handhelds making noise
• Gestural Android handheld music, as I demonstrate the possibilities of the Google Android platform and G1 phone for OSC
• The Arduino-based Hard/Soft synth, designed by Gijs Gieskes and built by MAKE’s Collin Cunningham
