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?)

SX-150 synth mod instructions, schematics and code [MrBook]

Via Collin Cunningham at MAKE, MrBook has a lovely rig with a modified Gakken SX-150, the synth kit that sells for US$50 in the States and has even been seen as a free add-in with Japanese magazines. He’s added MIDI control and a digital audio converter, and put it into a housing, which makes for a quite-playable instrument.

Really terrific work! Of course, a few thoughts:

• We need an OSC-compatible synth. (Anyone out there?)
• I love you, Live, but this looks like a perfect job for Numerology (for its modular sequencing) or Renoise (for tracking).
• Looks like more controls would make this even more self-contained.

If you have synth projects like this, we’d love to see them.

Pronunciation of some common music tech terms has been a source of debate. Generally, though, there’s only one right answer. I had hoped to kick off a pronunciation guide yesterday or today, but now I really can’t resist – not with none other than Tegan & Sara getting together to debate the right way to say Moog.

Don’t get me wrong. I love cows, and the sound “moo.” I suggest if you have something you want to name Moo, you should, like your own MooVerb max patch or something. However, here goes, a few of my favorites:

Moog: Rhymes with “brogue” or “rogue,” not the sound a cow makes. Don’t say “Moooooog” unless you want to get funny looks from synth nerds, or if you’re teaching synthesis to livestock in a dairy.

Monome: The community-based, (partly, at least) open-source controller rhymes with “MA gnome,” not the Spanish-sounding “Ma gnome ME.” You should not be able to use it in a couplet with paper mache. Get it? Two syllables. Sure, this pronunciation varies, but the two-syllable version is what the device’s co-creators call it.

OSC: Pronounce the letters of the open communications protocol, as in “O.S.C. / oh ess see”, not “osk” – though that would have been kind of cool. Think, “Rah, rah, rah, Give me an O! Give me an S! Give me a C! What’s that spell? Better than MIDI! Time-based messages, higher resolution, transport-independent high-speed networked communication with auto-discovery, gooooooooooOOOOO O.S.C.!” (People sometimes say this site is geeky. I have no idea what gives them that impression.)

And for now, O.S.C. stands for Open Sound Control, even though in one spot on the JazzMutant website it’s called “Open-Source Control.” Just get ready for this to change – because OSC really isn’t specific to sound, it may need a new name, like Open System Control. (A recent paper suggests dropping the “sound” in the name.)

MIDI: Rhymes with G. Gordon Liddy, or P. Diddy, or Tweetiebird saying “Piddy.” And, actually, it occurs to me I’ve never heard anyone mispronounce this. Fascinating – an acronym that’s actually intuitive. Oh, but “C.C.” stands for “Control Change,” NOT “continuous controllers” — look at the CC specs; most aren’t continuous. There. I got to be anal about something anyway. Updated: consensus is actually that “mee-dee” is a mispronunciation for native-English speakers, but likely makes more since than “mi-dee” in other languages — particularly if you speak French. So, in other words, it’s an acronym, and makes the most sense to pronounce in the natural way you would in your native tongue. (For English speakers, who knows what vowel sound is appropriate given how screwy our language is, but the creators of MIDI all say middy.)

Maschine: Native Instruments’ drum machine software and controller is German-engineered, so say “muh SHEEN uh,” three syllables, as if you grew up in Berlin. Now, granted, Maschine’s own promotional videos — outsourced to the US — anglicize this to “machine” / “muh SHEEN”, but the engineers and product folks who built the thing use the German pronunciation and think you should, too. And, anyway, it sounds cooler, just as I have to admit a currywurst is tastier than a Nathan’s dog.

I’m sure this is only a small selection of potential mispronunciations. Other candidates? We’ll have to release a full pronunciation guide soon.

Moldover 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.

Our friend Matt Moldover is a mad scientist of controllers. Stock Novation and M-Audio keyboards enter, and wind up coming out as live musical control monsters. You know that kid who mashes up toys in the first Toy Story movie? It’s like that, only musically productive.

Moldover has been steadily perfecting what was originally the Octamasher, a set of M-Audio keyboards connected to a central Ableton Live brain. The basic concept is a powerful one: instead of one person, one set of secret mappings even the performer (cough) sometimes forgets (yeah, that’s me), and one computer behind which he can hide, get a bunch of people jamming and remixing live – even if they’re new to computer music.

The Syncomasher is the latest iteration, and it’s looking utterly beautiful. It can be an installation toy or a serious performer instrument – or both at once. Check out the new custom body – which still retains that whimsical Moldoverism.

Check out this controller modification how-to, as well, from last year:

Okay, Google Android fans — your apps are starting to arrive, especially as Google continues to improve the SDK.

First up, here’s a demo of the new app FingerPlay MIDI, which turns Android into a simple touch controller. True, we’ve seen similar things on iPhone, and Apple’s platform has precise multitouch which Android lacks, but it’s nice to see the concept extended across platforms. Big thanks to postromantic on Twitter for the tip! (Follow cdmblogs for more.)

FingerPlay MIDI

I can’t tell yet if this will be open source – that would actually be nice, I think, as it’d allow the community of developers to have a shared set of tools. (In fact, it seems a logical model would be to cash in on general-market apps and open source the more music-specific, niche stuff.)

In other Android mobile news, Christopher Souvey continues to work on his Musical application and the Musical Pro desktop app. The desktop client works with MIDI over Wifi, and thanks to the Cupcake OS update, latency is greatly reduced after a complete rewrite and the creation of custom drawing and event handling and controls. Check out the slick new tuner and UI Christopher has been developing, too.

This play-along piano is probably not something any of you folks desperately need, but it is a good demonstration of what’s possible.

Another interesting thread to follow will be the growing power of Web apps. On Android, you’re already able to combine a Web app with the Java APIs, and going another level, mobile apps with native ARM code for the processor. Translation: while phones still have a fraction of the power of your computer, it’s getting easier for developers to work across platforms and to take advantage of what power is there. That’s leading to trends that could be of use not only to a single platform (Android, iPhone), but to mobile devices in general.
