New York startup littleBits and founder Ayah Bdeir helped pioneer the modern definition of open source hardware. But they also put it into action, getting even young kids snapping together their own hardware ideas. The process is addictively simple: whereas platforms like Arduino require breadboards and wires, littleBits’ tiny circuits are already pre-made and snap together with magnets.

It’s an idea that screams out for sound applications. And now – in a collaboration that leaked earlier this week – that’s happened. The surprise is, the collaborator is none other than KORG.

The price: US$159 (direct, and at some retailers).
Shipping: Beginning of December.

That buys you a box full of miniature circuit boards containing the basic elements of a synthesizer: a keyboard, a sequencer, oscillators and filter and envelope, and even a delay. (We have full details of the modules below.) The oscillators and filter and delay were derived from the KORG monotron, meaning the filter circuit is the latest adaptation of the MS-20’s filter design. (This one uses the second-generation MS-20 filter, not the original filter as found on the monotron, though the character isn’t entirely different.) They’ve undergone some modifications to make them work in the littleBits set, but they still retain their distinctive sound. And that means what you get is perhaps best described as a build-your-own monotron prototype.

Where this gets interesting is that you can mix and match the synth kit with other littleBits projects, adding motors or blinking lights or sensors. It’s definitely pricier and more limited than using something like Arduino, but you don’t have to muck about with breadboards, wires, code, and soldering irons. Almost everything just works. And it could easily be a gateway – or rapid prototyping solution – to those other systems, especially for kids (or anyone in a hurry).

The best way to see what this means is to watch Reggie Watts’ cute demo video. It happens fast, but take particular note of the moment when he adds motor-driven animated figures – something you can’t easily do with a conventional sound modular.

I’ve been in touch with KORG’s Chief Engineer Tatsuya Takahashi (the man behind the monotron and volca series), littleBits’s Product Development man (and music tech lover) Paul Rothman, and KORG Product Originator Tadahiko Sakamaki. Mr. Sakamaki might well be called KORG’s Chief Cool Officer, having brought the volcas and monotrons, the Kaossilator, nanoSERIES, MS-20 mini, and others to market. They spoke to me earlier this week from New York via Skype. Audio isn’t terribly great, but I can share what I learned. (Kudos to the KORG gentlemen, who were cogent despite having just gotten off a flight from Japan.)

I’ve also had a hands-on demo with Paul (who made some fascinating little combinations) and just received a pre-production set; we’ll have some sounds for you next week.

First, here’s what comes in the box:

Power: On/off switch, 9-volt battery connection (included)

Oscillator: (2x) Single oscillator source, switchable to square and saw, with pitch knob (plus tune, which works when you plug in the keyboard)

Random: Noise oscillator. Switchable to two modes: “Noise” outputs white noise; “random voltage” is used for control (playing random pitches – think a sample & hold generator)

Keyboard: 13 switches give you an octave of notes; there’s a dial for register. “Press” mode is momentary; “hold” sustains the pitch. You actually get two outputs: the pitch output, but also a trigger output for controlling other modules.

Micro sequencer:Step through four sequence values, each set by a knob. You can clock the sequencer either using the knob or externally (in step mode). That means you can trigger steps (via the keyboard, for instance), or send a pulse for external clock.

Envelope: Attack and Decay knobs, for a simple two-stage envelope.

Filter: Cutoff, Peak (Resonance); with Peak all the way up, the filter will self-oscillate (which means you have a third oscillator, if you like).

Delay: Time, Feedback.

Mix: Two inputs, one output. You also can use the Mix module two combine the two oscillators.

Split: (2x) One signal input, two signal outputs.

Synth Speaker: This module has a small speaker atop it, plus a volume control, but it also has a 3.5mm minijack output for headphones or line output.



These modules come with a booklet that explains their function, plus all the basics of sound synthesis. It also has some fun projects, with warnings to get adults’ help. (Okay… uh… I still imagine all of us grown-ups raiding the paper plates and causing mayhem with the hot glue gun.) This includes novel routings for making practical synths, and physical modifications – like building a keytar, or attaching straws and plates to the knobs to make a DJ-style platter interface.

Now, for some questions and answers – it’s easiest to summarize this from the conversation we had:

Can you perform with these? Absolutely. “Tats” joined Reggie Watts and chip musician Nullsleep onstage at Le Poisson Rouge in Manhattan this week. He told me that he already had the synth kit ready to go, and soldered a single wire from the underside of one of the modules to a volca for clock, for an impromptu volca + littleBits concert.

What about MIDI? There’s no MIDI yet, though Paul tells CDM that littleBits would like to release such a module in future. But it wouldn’t be hard to hack other connections, analog CV or MIDI.

How close are these to the monotron circuits? Tatsuya says there was a bit of work to adapt the circuitry to littleBits, first and foremost the non-trivial issue of making everything run at 5V. But they are otherwise quite close.

Wait, did KORG just release open source hardware? Yep. And that makes KORG the first major manufacturer to do so explicitly. It’s not available yet, but circuit designs under an Open Source Hardware license, plus firmware for the digital modules, will be up on GitHub along with the other littleBits modules. That means you could theoretically devise your own synth based on these circuits if you really wanted. The only thing that isn’t open is the proprietary design for the magnet-snap attachments. Whether that’s a business decision or not, it’s also a practical one. Paul says you’d need special equipment to mold those tiny plastic parts. (I expect 3D printing on most readily-available affordable printers could cause problems with fit.)

I asked (and even Tatsuya asked) if this was a significant issue for KORG. Tadahiko said there wasn’t even much discussion; the company was pleased with the enthusiasm from customers over releasing circuits like those for the monotron. Adding the explicit license almost sounds like a (generous) afterthought.



What if you want to make your own modules? This isn’t really possible yet – though attaching a wire as Tats did is easy enough. But Paul says that a Hardware Developer Kit is in the works which would allow people to create their own modules. It seems that the music and sound community will be all over that, even more so than the existing people using littleBits.

Why does KORG keep doing this cool stuff? I talked to Tadahiko a bit about where the motivation to do this at KORG originates. He spoke really passionately about the desire to do “interesting” things – that all the way to the top, chief Kato Seiki makes doing interesting things, things that make customers happy, comes first, even before business considerations. And having a company that investigates ideas first and then thinks about the business case to me is fascinating.

What modules might you add on? There are “exploration” kits full of lots of options, but Paul when he was in Berlin demonstrated four that are also displayed on the included booklet, and they make a lot of sense. There’s a microphone, which also lets you input signal – perfect for using the filter. There’s a pressure sensor. There’s also a bar graph (which displays levels anywhere in the signal chain, though it’s more useful in some spots than others). Or you can go crazy with ideas like (EL) light wire.

I’m really excited to see what people do with the littleBits series, partly because there’s now a resurgence in interest in DIY and modular. This isn’t necessarily the best or most practical synth you can buy for $159, absent MIDI and some other options (and without a case). But if you are willing to spend a bit of extra money on the convenience of the magnets, and want to piece together your own, very tiny modular, it’s a crazy amount of fun.

And Tatsuya said something interesting about the motivation behind these. I asked, clumsily, if there was some sort of renewed interest in DIY sound instruments. Tatsuya went further, and said he thought people were interested in exploring sound. Understanding that as the main motivation behind all we do, behind our desire for these tools, I think can’t be overstated.

With that, I hope you get some music making time this weekend. Enjoy, and see you next week.

If you’ve got more questions about the littleBits, let us know so we can include them in our review.

    instant xmas gift

  • Sylvain Poitras

    I can’t wait for my daughter to be old enough to play with these…

  • WetBoy

    So the video suggests there are 3 boxed versions, kind of ike a Starter up to a Pro kit.

    No mention of these in this article?
    Looks great but pricey compared to the Patchblocks IMO

    • Charlie Lesoine

      The 3 different versions are non synth kits. There is only 1 synth kit.

  • gli

    really cool to see how much korg cares

  • Shmerdjee

    Patchblocks looks nicer

  • Will

    These look so fun! High Five @ Korg.

  • shim

    note to the food network: just add reggie watts to anything and it is killer. sniff…i love reggie as only a man that loves a man that loves women can. this could be a portlandia ep.

    I HEART ME SOME WATTZ!!! yerp.

  • Scamstar

    Remember when Korg was a serious synth company? Most of the new stuff looks like toys, and more importantly, they FEELS like toys. Sure I know about the kronos, and the highend stuff. But look at other companies. Novation, Waldorf, Arturia, Dave smith and even Moog. They all strife to bring us real instruments at affordable prices. What if korg dropped its toys and “select sound by genre” keyboards, and started to make innovative stuff at compatible prices! But no…. Instead we are left with a relaunch of an ms20, overprices higend synths, and a toysRus segment, that is far inferior to the likes of what you can find on kickstarter. Shame on you Korg! Ask yourself this question: If some of the great classic synth companies where to be resurrected, like Oberheim, ARP, Ensoniq and the likes. Do you think that they would be developing these kind of insults to the established music composers and engineers? I think not. I wonder at what price Korg could offer me a kronos synth, if they dident have to use money developing these kind of fisher price instruments. I I own an original ms20, and many other classics! I know what a real synth costs! But these other synth companies are offering great new instrument, with great sound and architecture, at affordable prices, and Korg are putting out toys!? Really?

    • just passing

      Tissue for your chin, there?

    • Jaybeeg

      This is a product by a NYC-based company called littleBits. Korg simply collaborated with them on the design.

    • Greg Lőrincz

      Dude, it’s NOT Korg. Read the article again. It might be a toy but the best one I’ve seen in years. Don’t get upset about companies not catering your specific needs!

    • http://pkirn.com/ Peter Kirn

      Well, the sound circuitry is 100% KORG, to be fair. So anything to do with sound, you can blame on them. :) (within the constraints imposed by littleBits … running everything on 5V is an exciting challenge, I’ll say!)

    • Greg Lőrincz

      That 5V thing is pretty impressive. How the hell? I guess they used low-power components but still… The circuitry is 100% Monotron. In other synths, such as the venerable MS20 they used LM13700 (or LM13600) OTAs rather than transistors for the CV control of the filter. I know, splitting the hair….

    • Greg Lőrincz

      “I wonder at what price Korg could offer me a kronos synth, if they dident have to use money developing these kind of fisher price instruments. I I own an original ms20, and many other classics!”

      I wish you just didn’t say that. I can’t take you seriously. I don’t think any once can.

    • http://pkirn.com/ Peter Kirn

      Heh, I think you deleted your earlier rant. Fair enough.

      I mean, I have a different take on the volcas. I think the volca keys is an utterly brilliant synth, and not a toy.

      And, honestly, much as I love the KAOSS series and the Kaossilator, I can live without those devices. But the volca series and monotron and, yes, even the reissued MS-20 mini to me make some really unique sounds and can be valued as proper instruments.

      Now, does this leave plenty of room left over for the other synth makers you mentioned? Hell, yes, it does. It’d be boring running CDM if it didn’t. There’s a lot to be done in digital and analog instruments alike.
