Lured by the siren song of modular synthesis and DIY electronics, but not sure how to navigate the piles of requisite knowledge – or uncertain what the trip down this rabbit hole might have in store?

For years, Tom Whitwell’s Music Thing was a beloved daily read, as that site and this one were among the early blog-format destinations for music tech. Tom moved on – something about a major day-gig at a paper called The Times, perhaps named after the font? – but that makes us all the more delighted to get a dispatch from him. In this guest column for CDM, he introduces one project, a brilliant FM radio sequencer, but also helps us catch up on reading on modular synthesis and electronics dating back to the origins of the technology. And he has a realistic look at what this will do to your life – all inspired by “pure enthusiasm,” as he puts it, “this is fun, you should try it.”

Hey, isn’t that what the drug dealer said in those just-say-no instructional videos we watched in the 80s? Coincidence, I’m sure. -PK

Since buying a Eurorack modular synth a year ago, I’ve spent a lot of time building DIY synth modules and reading about synths and the people who build them. (See reading list, below, if you’d like to do the same.)

The hardest part of DIY electronics is starting out. My first step was building a few guitar pedal kits and learning by reading the Beavis Audio site. Other people start with noisemaker kits like the Atari Punk Console or circuit bending. They all lead in the same direction — down a very deep rabbit hole. 

There’s a lot to buy – a kind of infrastructure you need before doing anything – soldering kit, a multimeter, and a stock of components. None of it costs much, but it’s hard and disconcerting to buy. Online megastores like Farnell or Mouser will stock 50 versions of every component. Get the part number wrong, and you accidentally order capacitors as small as grains of sand, or as large as golfballs. Smaller stores – in the UK, I use http://www.bitsbox.co.uk/ - are easier because they only stock common hobby-friendly parts. 

After making a few guitar pedals, I moved onto synth modules. They’re a great DIY platform. The infrastructure is all there, in terms of power supply, case, inputs, and outputs. Parts are cheap, there’s a healthy and helpful community, and a nice learning curve, from basic utility modules to mind-bendingly complex frequency shifters and vocoders. 

In a year, I’ve built:

• a super-simple, chiptuney oscillator
• a tiny spring reverb driver
• a stupidly-complicated and blinkenlights-covered Arduino-powered Euclidean beat sequencer
• a very useful Arduino MIDI clock
• and a simple but handy 8-step sequencer (see video, below)

For this project, I was inspired by this quote from Don Buchla, the legend of west coast synthesis: 

“My studio at that time was ten feet wide. It was so crowded in there we hauled the workbench out on the sidewalk on good days and set up my oscilloscope and worked out there. [John] Cage came by and for voltage control I had hooked up my keyboard to an FM module that I’d built, a little module that was an FM receiver and I could play stations on it because I had one of the first varactor tuned FMs. Cage, as you can imagine, was just enormously interested in the fact that I could tune each key to a station and then proceeded to play the radio” ( Source [PDF] )

Thirty years later, Don released the 272e module (see Matrixsynth on the announcement), a $1250, four-channel polyphonic FM Tuner. There’s also the ADDAC102, a very fancy stereo €270 Eurorack module [see Synthtopia, with a video]. I wanted something quick, cheap and easy that would let me follow in Don and John’s footsteps. After a lot of searching and a few dead ends, I found the wonderful video demo, below, of a battery-powered FM sequencer based on a €15 radio kit from Germany. 

Projects like this follow a predictable curve. There’s a burst of experimental excitement at the start; receiving the crucial part, building the circuit on breadboard and realizing that — YES! — it’s going to work. 

Then comes a period of frustration and tedium. Re-buying a crucial part you blew up. Fiddling with the circuit so it responds just how you want it. Transferring the breadboard layout to a piece of perfboard, or designing a PCB and waiting for it to be made in China. If you’re using an Arduino or other programmable controller, there’s a long period of writing code, battling feature creep, debugging. 

During this period, you have to really, really want the thing you’re making, dreaming of how cool it will be, how much fun you’ll have playing it and telling everyone about it. 

Tom's FM radio-sequencing module project, in all its glory.

Building music gear is more multidisciplinary than you might imagine. The interface and the feel is as important as the functionality. My Euclidean sequencer is a cool-looking thing, with a big LED matrix. It’s really useful – turning trains of pulses into Afro-Latin rhythms. But it’s fiddly and annoying to use. The FM Radio module could be 50% smaller – and size is important in any modular synth – but this time I wanted good big knobs for fine tuning the signals and control voltages. 

So, as the project continues, you’ll spend time designing a front panel, deciding how many knobs you need, removing ones you’ll never use. And along the way, you’re learning. This time round, I wanted to get the control just right – precise, stable tuning so that stations would stay locked. That meant experimentation and [asking for help on the MuffWiggler forum]. I also spent ages reading ham radio sites, trying to work out how to make a voltage-controlled Shortwave radio (I gave up). 
Eventually, the lacquer is dry on the panel, the parts are all in, debugging is complete and the module is working. The result: either elation and fun, or almost immediate maker’s remorse. It’s bad enough spending money on a piece of music gear that you never love. It’s really annoying spending time building one that you can’t then flip on eBay. 

So far, this FM module is pure fun, an injection of random audio in the heart of the system. Every time I turn it on, something else comes out – pirate dubstep stations, Turkish music, news reports and Bryan Adams. You can filter it, sequence it, use it as a noise source, or let it modulate oscillators or open filters. Listen:

Reading List

Great online resources for learning about modular synths and the first golden age of experimental electronic music include: 

Ubuweb’s electronic music resources section 
Also at Ubuweb, several editions of Electronic Music Review, a beautifully-designed but short-lived journal boasting Robert Moog as Technical Editor. 

The Red Bull Music Academy includes long, detailed interviews with Don Buchla, Tom Oberheim, Peter Zinovieff of EMS, Robert Moog and Morton Subotnik.

Synapse magazine was a mid-70s journal of electronic music, where you’d find DIY projects from people like Serge Tcherepnin

Vasulka is a huge and rather poorly-organised archive of documents, interviews and transcripts, containing some gems.

Source Magazine was, back in California in 1967, a plush avant-garde journal. Many editions came with 10″ vinyl records, pages printed on transparencies or fur. John Cage was a guest editor, and the magazine carried experimental scores from composers like Steve Reich. Original copies sell for $500+, but the articles and scores have been collected in a book:

What’s Next?

Tom is already on to the next build since he finished up the radio sequencer. This time, it’s a shift register sequencer. A what?

A 16-step random sequencer, something between the Wiard Noise Ring, the CGS Gated Comparator and Nav’s BITSY.

It takes random noise to fill up 4 x 4 step 4015 shift registers, shifted by a clock input. The shift registers are looped – either after 8 or 16 steps. 8 of the steps are fed into a DAC0800 analog/digital converter, which produces a 0-8 volt output.

Electronic music making has had several major epochs. There was the rise of the hardware synth, first with modular patch cords and later streamlined into encapsulated controls, in the form of knobs and switches. There was the digital synth, in code and graphical patches. And there was the two-dimensional user interface.

We may be on the cusp of a new age: the three-dimensional paradigm for music making.

AudioGL, a spectacularly-ambitious project by Toronto-based engineer and musician Jonathan Heppner, is one step closer to reality. Three years in the making, the tool is already surprisingly mature. And a crowd-sourced funding campaign promises to bring beta releases as soon as this summer. In the demo video above, you can see an overview of some of its broad capabilities:

• Synthesis, via modular connections
• Sample loading
• The ability to zoom into more conventional 2D sequences, piano roll views, and envelopes/automation
• Grouping of related nodes
• Patch sharing
• Graphical feedback for envelopes and automation, tracked across z-axis wireframes, like circuitry

All of this is presented in a mind-boggling visual display, resembling nothing more than constellations of stars.

Is it just me, or does this make anyone else want to somehow combine modular synthesis with a space strategy sim like Galactic Civilizations? Then again, that might cause some sort of nerd singularity that would tear apart the fabric of the space-time continuum – or at least ensure we never have any normal human relationships again.

Anyway, the vitals:

• It runs on a lowly Lenovo tablet right now, with integrated graphics.
• The goal is to make it run on your PC by the end of the year. (Mac users hardly need a better reason to dual boot. Why are you booting into Windows? Because I run a single application that makes it the future.)
• MIDI and ReWire are onboard, with OSC and VST coming.
• With crowd funding, you’ll get a Win32/64 release planned by the end of the year, and betas by summer (Windows) or fall/winter (Mac).

I like this quote:

Some things which have influenced the design of AudioGL:
Catia – Dassault Systèmes
AutoCAD – Autodesk
Cubase – Steinberg
Nord Modular – Clavia
The Demoscene

Indeed. And with computer software now reaching a high degree of maturity, such mash-ups could open new worlds.

For the last few decades, generally speaking, we’ve had computers, and we’ve had physical, modular, analog gear. Computers are endlessly patchable, but not using physical cords. Modulars use physical cords, but they lack the flexibility (and affordability) of a computer.

Now, US$25 and an Arduino can change that.

rePatcher is a simple, tangible modular interface for computers. It could work with any software, but right out of the gate it already works with two popular (virtual) patching environments, Max/MSP and the free and open source Pure Data (Pd). You use physical patch cords to make connections, and those connections are reflected in the patch you see on the screen. The patch cords are coupled with requisite encoders for dialing in additional parameter changes. (Reason comes up as a possible candidate for additional compatibility, which would, of course, be really sweet.)

rePatcher is built as a shield for Arduino, so you’ll need one of those, but that still keeps the price low enough to say I absolutely have to have one of these right now.

It’s not the first attempt to do something like this, but it might be the most accessible and affordable – and interesting. And while those cute little patch cords are fun, there’s nothing stopping someone from building on this idea and going to bigger cords and something more extensive than this 6×6 matrix.

Best of all: the magic happens entirely over USB, so if you want to make this work with something else – say, your favorite VJ software – you can do so with anything that can communicate over serial.

For the lover of musical instruments and technology, southern California’s NAMM show is a giant toy shop. It’s work for many of its attendees, of course, but we know many of our readers dream of the objects that will make their next creations. And sure, inspiring lust is not our aim; on the contrary, there is some love that goes into these things. In the ideal, that’s the relationship of creator and consumer. These are things not to be bought and discarded, but kept and really used.

So, we have a different look at the NAMM show, through the lens of CDM contributor Marsha Vdovin, who has been at this show more times than she might like to count. I’ve added some comments about what these devices are and why they’re important. And the next time we see them, these inventions pictured in silence here, we expect them to be working hard on music far from the din and flourescent glare of the trade show floor.

As always, click for larger images. Photos by Marsha Vdovin; words by Peter Kirn:

Roland’s V-Guitar marks a surprising collaboration, bringing the famed American guitar maker Fender together with the Japanese electronic maker to make an “electronic guitar,” merging the two company’s tech on a digitally-augmented Stratocaster. More on this soon – but the extended playing techniques won over many guitarists.

The Danish design aesthetes of AIAIAI have improved upon their TMA-1 headphones with a studio model. Same drivers, same basic design, but a “flatter” response to sound (rather than beefed-up, DJ-ready bass) and closed ear design. It’s impossible to hear anything at NAMM, but I can attest that the new design is far, far more comfy to wear. Actually, if I could have kept these on the whole show to drown out the sound, it would have been great.

An easy place to spot a talented celebrity was at the Dave Smith Instruments booth, at which artists clustered around Dave and Roger Linn. They were on-hand with plenty of tweaks to their stellar Tempest drum machine.

Teenage Engineering’s OP-1 grew up, with new features (drum sounds! MIDI sync – at last), and grew out, with a companion product for connecting sensors and USB host mode that could be a boutique item for music DIYers. We’ll go hands-on with each this year, and while readers were disappointed on a lack of some details (will the OpLab be open source?), we expect to get more details from the Teenagers when the product is ready in the coming months.

Readers of tech blogs (ahem) may miss out on the fact that the vast majority of NAMM is really for guitarists, drummers, and traditional instrumentalists. And yes, that includes glittery, pink products from Daisy Rock Guitars. We’ve concluded this model will be perfect for Sparkle Pony. (And really, if you’re not watching Portlandia to get that reference, get on it. Also, Jenny Conlee is crazy awesome.)

Thin, responsive, and expressive, the QuNeo from Keith McMillen – funded on Kickstarter – proves it’s really happening. With continuous pressure response on its touch controls and bi-directional control, it could be the most anyone will ever have gotten from a US$200 controller. Yes, we’ll be watching.

Pioneer wasn’t showing anything new at this show — they timed those launches over the fall with new controllers like the Ergo. But they did have a glossly all-white lacquer set of limited-edition devices that looked absurdly gorgeous. Now if I want to do my flat over in the style of a Stanley Kubrick set, I know what DJ gear I’ll be buying. (If you don’t know what I mean, watch the end of 2001 again – or the living room in Tron: Legacy, which is more or less a copy.) White is the new generic-dull-charcoal.

Akai’s MPC Renaissance is unlike any other mass-market controller we’ve seen. It’s actually substantial, something that feels like a vintage MPC even though it’s designed to work with software (pictured). The audio circuitry is straight out of the modern MPC, but there’s a switch for “vintage” modes – think 12-bit output when the MPC60 is enabled, for instance. Akai told CDM they built the software in-house, but we also learned at NAMM that they licensed time-stretch tech from iZotope, giving their upcoming MPC software generous audio-manipulation abilities.

The Renaissance will cost you, with a street expected well over a grand, but that makes it even more welcome that the same superb pads and response curves are also on the maker’s MAX49 keyboard and cheaper MPC Model.

Just expect to wait: these were prototypes, and there were still some bugs to work out.

The Renaissance is for the MPC die-hard; the MPC Studio is the model that will directly take on Native Instruments and Maschine. It’s slim, sleek, and still has great-feeling controls. And while that makes it compelling competition for Maschine, I’m gratified to see this whole market expanding, new workflows for performance and production, and a push to better quality in the controllers. The days when computer gear meant “cheap and plastic-y” are mercifully at an end. Speaking of which –

Akai’s MAX49 keyboard could be a new model to beat. The keyboard action is satisfyingly springy, with a new keybed not seen in previous models. The pads are identical to those on the Renaissance, and feel more the way proper MPC pads should. Not everyone will love the light-up, touch-sensitive resistive faders, but I found with a bit of pressure, they worked well – and that means never having to worry about a fader catching up with the value in software. You also get serious features: Control Voltage, a full complement of MIDI ports, and aftertouch. Did I mention Control Voltage? It’s nice to see a controller keyboard with a slightly premium price, build, and features.

The last surprise from Akai was this MPC DJ. The company says it’s a prototype only, and had little more to say about it, but it’s fascinating to see the MPC and turntable controls converge.

Moog’s Minitaur was my favorite synth of the show. It just sounds consistently brilliant, no matter which way you turn it or play it – and I accordingly noticed it was the synth the most people were actually playing on the show floor.

This is what a 24-karet KORG MonoTribe looks like, alongside a silver-plated model. There’s little more one can say. It is, of course, one of a kind — and already spoken for.

The other thing of beauty at the KORG booth: a limited-edition reverse-key SV-1 keyboard.

iOS accessories were numerous, but a few were genuinely useful. IK Multimedia’s iRig Mic “Cast,” for instance, is coupled with handy software for podcasters, as a quick tool for interviewing or podcast recording.

It’s not a new product, but one of the reviews to which I’m most looking forward is this Eers product. It promises custom in-ears you make yourself, rather than the enormous cost of getting them custom-made. Stay tuned on this one – protecting your hearing and making on-stage gigs go well is perhaps as essential as gear can get.

The just-intonation Hymnatron from the Dewanatron crew was one of the most compositionally-compelling instruments at the show, with a unique sound, tuning, and key layout. And it looks mighty handsome in this one-off wooden case.

LiveWire’s modular was among the many dreamy modular rigs at Big City Music and Analog Haven, two Los Angeles hotspots for analog modulars. Did we mention space was more plentiful and inexpensive, and gigs more generous, in LA than in NYC, Chicago, or San Francisco? Funny coincidence, that.

Many modules graced this show, but the most intriguing was not analog, but digital – think digital algorithms in an analog, patch-cord-modular hardware workflow. Tom Erbe, maker of long-beloved SoundHack (the app, and then more recently the plug-ins) put some of his sonic wizardry into a module, collaborating with one of our favorite modular builders, MakeNoise. The result: the MakeNoise Echofon. As such, it’s a perfect emblem of our Create Digital Music, Create Analog Music philosophy. Dear Berlin friends: let’s plug this into your monster modulars, okay?

Big City Music is a wonderful place. The other candidate for best new module: brilliant creations by Metasonix, as previewed here. We’ll be watching for these to be patch-able, too.

Casio had its classic CZ-1000 synth on-hand at its booth. The Casio XW isn’t quite a successor to the CZ, though it does include some of those waveforms and phase distortion sounds. What it does appear to be is a very affordable, do-just-about-everything workstation at a fraction of the price of any of its rivals. For someone who wants a jack-of-all-trades gigging keyboard, this could very much be a contender.

Our friends at Beatport are evidently getting into the hardware business. The most interesting launch wasn’t a set of TMA headphones with Slimer-green cords (I’ll take the Studio model, thanks, or just a non-Danish set of studio cans). Instead, I was intrigued by the eminently-practical line of gigging cords Beatport is working on with Hosa. They include features live digital musicians and DJs badly need, like color-coded cords you can find easily at a show, and hinged USB cords you can cram into tight spaces. More on those soon.

Thanks, all. Lastly, I want to thank everyone I got to spend time with at the NAMM show, and particularly Marsha Vdovin, who is responsible for these photos and keeping our schedule together. NAMM is always too crowded and too short, but it can lay groundwork for a whole year. And I’m excited for this Year of the Dragon. Be seeing you.

Metasonix, the maker celebrating the mad science of tubes for making wonderfully-terrible noises, reveals to CDM that next week they’ll unveil a new Voltage Controlled Oscillator. Behold, videos! From top:

“A prototype R-55 thyratron VCO is controlled with a Makenoise Rene sequencer, with an R-54 VCO tuned to track along.”

“A prototype R-55 thyratron VCO tunes along with an R-54 VCO, both driven with the same CV.”

Analog: you can scare small children with it. In a good way.

And as if you needed another reason to visit their booth at NAMM – or follow along as we visit them virtually here on CDM – Metasonix will have this prototype at the Big City booth. Big City Music, a California treasure trove of boutique music hardware and analog goodies, is a place I’m always willing to evangelize. Metasonix writes CDM:

“This is a prototype, the finished ones will be slightly different.

If people want to see more, the R-55 will be on display at NAMM, at the
Big City Music booth (6735). I won’t be there but Josh can demo it.

They are expected to ship May 2012.
BCM is getting an exclusive distribution on these and the quantities will be limited. ”

Touchable tablets may be all the rage at the CES trade show, showcase to consumer-friendly gadgetry. But quietly, developer Sensomusic has accomplished multi-touch control of an open-ended music system on standard-issue PCs and accessories. They’ve pointed the way to just what this mechanism could be.

The latest video isn’t terribly easy to see, but it realizes something that has been the dream of fans of the music control protocol OSC (OpenSoundControl). “Learn” functionality lets you touch a control, then assign that control to something in your music software. But because these functions have relied on MIDI, they’ve generally been a bit arbitrary – touch one thing at a time, get a number for that thing, then assign that number to a controller. It works well enough, provided you step through each control. OSC promises to do more, though: an arbitrary touch controller on, say, your iPhone (or anything else) can have a plain-English name. And you can see multiple parameters appear on the screen at once, so that a sensor or multi-touch pad could have all its messages pop up at the same time.

Finally, Usine does OSC Learn correctly, with messages that pop up with names and get connected to whatever you like. I still think there’s more potential here to be plumbed, but it’s a great step.

If you don’t follow why that’s cool, check out another mapping notion from last year – here using a touch panel to make any graphic playable. And at the end of this story, check out the clever multitouch gesture recognition they’ve added.

Again, all of this you can do with standard-issue hardware – Apple iOS hardware, if you like, controlling a PC, or non-Apple hardware displays with touch or Android devices and the like. (Unlike the Emulator we saw earlier today or the original Lemur device, it’s a software solution that works with your hardware of choice.) More to watch:

Modular music making is a throwback to the early days of electronic music, in which a spaghetti of patch cords is the price of open-ended sound creation. Fairly or unfairly, it has often been viewed as the domain of the eccentric wealthy musician. You needed cash, endless patience, and lots of space – well, unless you happened to be lucky enough to pick up a vintage modular as people were getting rid of them.

But something has happened: modules have become more practical and accessible. Like any music technology, they can become a rabbit hole into which time and money fall and no music escapes. But also like any music technology, there are ways of bending these tools to your will, applying fiscal and creative discipline to make them musically productive.

Enter the “desktop modular” revolution. Modules are cheaper and more usable. It’s easier than ever to assemble a rig of modular that coexists with your digital gear, be it MIDI hardware or computers. That means just a select set of modules within your budget (and available physical space) could find a place. And modules are more innovative and fun than they’ve been in the past, too. They merge digital and analog tech – just as this site has loved doing (despite our name) over the years.

And just as suddenly, that spaghetti entree starts to look delicious.

I can’t say I’ve personally found room for this kind of gear, but I’ve enjoyed watching the evolution of new equipment. And over the past few months, I’ve witnessed a bumper crop of terrific new modules. It’s time to survey some of that fertile landscape, as 2011 winds to a close. Here are a few of my favorites, sure to inspire other nominees from readers. And I imagine this adds fresh cause to venture into the basement stalls of the Winter NAMM music manufacturer trade show in Anaheim next month, where these sorts of less-mainstream devices flourish.

Notably, these modules all work with the ‘small’ Eurorack (A100) format. German maker Doepfer Musikelektronik popularized this format, and it has since taken off. In fact, that puzzled quite a few readers when Moog’s re-entry in modular eschewed that format. (That may be their loss.) But Moog ladder filters aside, there has been plenty of action in the Eurorack space.

Utility: Kenton MIDI-to-CV and More

Kenton’s Modular Solo is about as nice a utility knife as you could add to a modular rig, for integrating lots of different gear. Plug it in via ribbon cable, and you get:

• MIDI in and out
• SYNC 24 (“DIN SYNC” – think 808 and 606 drum machine sync)
• CV analog and gate output
• Two clock outs, four aux outs (think assigning MIDI to filter cutoff, etc., says Kenton)
• And an LFO – triangle, saw up and down, square, S&H pulse width with several fixed widths

£195.00, though all the extras there easily could make it worth it.

Utility: Expert Sleepers ES-4 Modules

Expert Sleepers’ ES-4 is the latest of their modules, turning a standard S/PDIF signal into five channels of control voltage. Coupled with their Silent Way software, you can also use it for MIDI, only with sample-accurate timing. That makes it a sample-accurate MIDI interface, if you like. (See video at top for a MIDI demo.) You can turn three of those five outputs into any signal you like – gate, envelope, LFO, and so on.

Where do you get that S/PDIF output? Well, lots of audio interfaces have them, and many computers – including recent MacBooks – do, as well.

There’s also an ES-4 Gate Expander add-on for additional 8 on/off gates, triggers, clocks, and so on. The unit is £151, or £64 for the Gate Expander, not including VAT.

More demos:

Sound Sculpting: ADE-10 Reactive Shaper

Justin Owen of Abstract Data sends us this creation. It’s an all-analog waveshaper, wavefolder, feedback unit, with audio to LFO range. That means you can use it as an LFO or design sounds or manipulate synth pads or … any number of things. In fact, it’s nice enough that I could see using it alone, sort of Moogerfooger / stomp style. This is the same nice gentleman who created the Kicker, a synth focused on bass drums.

Loads of sound samples on SoundCloud, in addition to the video tutorial and demo above. It’s yours for £135.00, which I think is quite a bargain.

ADE-10 Reactive Shaper Eurorack Module (2011) by abstractjuz

Synthesis: Monotron in a Eurorack

A bit more left-field, but you can even get Korg’s simple-but-fun Monotron synth in a Eurorack module. Skip ahead in the video below to hear it in action. (Well, unless you prefer field recording crinkly wrapping sounds, in which case the unboxing portion of the video will be your favorite. Toddlers, dogs, and gear lovers agree: unboxing is the best part.)

US$249 puts the Monotron in a rack format. Of course, there, you can do quite a lot more with the Monotron than you can with the original, with both full CV and MIDI control and very, very nice knobs, in place of the awful-feeling (though stunningly inexpensive) controls on the original. All together, that makes a very playable, very fine synth.

Synthesis: Triangle Core Oscillators

Just when you think you can’t innovate in something as simple as an oscillator — you can.

Synthesist Danjel van Tijn sends news of the Dixie VCO, which, named for its creator, reimagines how to do a triangle oscillator:

It is a triangle core oscillator in Eurorack format that utilises a brand new method of implementing a triangle core oscillator using a design by professor David G. Dixon.

Side note: Trianglecore would make a great genre name.

Professor Dixon co-designed the module and collaborated on its construction. In the video at top, you can see what those waveforms look like. Below, you can see how this might work in a musical context:

Melodic demo of the Dixie VCO. Two Dixies are used (only one at first) along with a Z8000 for sequencing, a uScale for quantizing, uStep for step sequencing and everything is filtered through the new Dr. Octature VCF/VCO.

The uScale is used to help demonstrate the extremely wide and accurate range of tracking of both VCOs. The sequence spans many octaves but the intervals of the two Dixies stay in tune.

PWM, LIN FM and Sync are all played with along with different combinations of waveforms to explore just some of the timbre possibilities.

And here’s what happens when you reverse sync:

We seem to lack purchase info on this particular module for now, but there are loads of other great modules from this Vancouver, Canada-based builder – and yes, they work with Max/MSP and computers, too, not just modules:

http://www.intellijel.com/

Roundup of Other Great Picks

Knowing I could never keep up with all that’s happening on the Eurorack scene, I asked Danjel aka Intellijel to give us some of his picks for some of the coolest modules. He obliged with a drool-worthy – and I dare say genuinely musical – list. Here are his favorites:

There is so much stuff! Eurorack has obviously tried to update or recreate most of the classic synthesis blocks from various manufacturers (Buchla, Moog, Roland etc. etc.) but the past couple of years very interesting developments have been made incoporating brand new designs not found anywhere else. Some of these are completely DSP based, some are hybrids and some like the Dixie VCO are %100 analog.

Other stuff I have put out that is unique (and actually has decent video) would include:

uScale: CV quantizer but it also does intelligent interval generation

Corgasmatron:
This is a dual multimode filter with the same transfer function as classic Korg MS20 but it is a completely new circuit design (nothing related to the original at all) using all modern components.

On the analoghaven page there is a list of about 40 manufacturers each with many modules:
http://www.analoguehaven.com/what/

The Muffwiggler.com forum is extremely active with all things to do with modular synthesis (and synths in general).

Stuff worth noting form other manufacturers (there is so much more from each of these groups):

Cylonix Cyclebox:
FPGA based extremely deep triple VCO with through zero FM and massive amount of synthesis and waveshaping options

Thanks, Danjel! This looks fantastic – plenty to consider as inspiration.

It all makes me wish for a holiday on which some supernatural being, against all rules of material consumption and the conservation of physics, flies around the Earth leaving, for free, the things you desire as gifts. If someone can make this happen, let me know. Also, I’ll need the contract to a flat in which I can house said materializing goods. Until then, I’ll have to hack something together for free in Pd and run it on a netbook.

Dream On: Modular, The Movie, and the Planner

Modular remains such a cultural phenomenon, it has inspired its own movie project, as seen on IndieGogo (trailer above):

I Dream of Wires: The Modular Synthesizer Documentary

If we’ve sold you on this whole idea, Danjel also points us to this:

There is a pretty cool online interactive virtual modular for planning out a system
It contains pretty much every module available.

More analog…

By the way, if you appreciate this sort of analog coverage and would like a domain at which you can see it, you should complain to Trash Audio. They cheekily registered the createanalogmusic.com domain and redirected it to their site, and they haven’t responded to offers to buy it from them them. I suggest you flood their inbox with complaints until they aquiesce. Alternatively, perhaps you can think of a word that means analog but begins with the letter ‘D,’ as that’d fit nicely with the ‘CDM’ acronym. Or we could come up with something in another language – German, for instance.

I’ve registered createanalogmusic.de for now; I’ll point it at something later this week. And as for how we can get back at TRASH_AUDIO — I’m open to suggestions. Can’t crash their NAMM party; I’ll be on a flight back to Berlin. (Seriously, that crew held a great synth meetup in LA in September I was lucky enough to catch – at least briefly.)

We’ll continue to happily bring you judgment-free electronic music making on a variety of platforms, from the Apple II to a discarded, broken cell phone to analog circuitry you wired up yourself, because that’s how we roll.

I’m not sure how everyone who owns an iPad uses it for music, but I find myself strangely drawn, more than anything else, to analog step sequencers. With MIDI connections – via a special interface or a standard USB MIDI interface connected via adapter to the tablet – you can even drive hardware. For me, the app of choice has been Little MIDI Machine. Developer Chris Randall has a new application in the analog-style sequencing category, though, called Phaedra.

If you haven’t grabbed it already, you have until the New Year to get it for US$4.99 before the price jumps to ten bucks. And you get an impressive array of features:

• Multiple buses, with 32 steps max each
• Programmable note, velocity, gate time, and two MIDI CC outs for each step
• Send or receive MIDI Clock for sync
• Use MIDI hardware (via Core MIDI), other apps (using “background MIDI” or OMAC), or your computer (networking via a MIDI Network Session

Phaedra for iPad [iTunes Store Link; you'll need iOS 5.0]

I wanted to know more about the creation of Phaedra. Developer and musician Chris Randall, known for his work with boutique plug-in maker Audio Damage, released this under a new moniker, Naughty Panther, which does iOS and MIDI development. Chris has been known to mix old and new, as with his musical use of the Apple II. Here, he gives us some insight into how he went through the design process on this new tool.

CDM: How do you sketch out the UI on a project like this? Paper and pencil?

Chris: Normally I just make notes in a little Field Notes notebook as I think about them — I carry one everywhere — then once I have a clear mental image of what I want to make, I just bust it straight out in Photoshop (or, for skeuomorphic interfaces like this one, a combination of Photoshop for the panel and 3D Studio Max for the knobs and buttons).

What inspiration did you consider as far as hardware?

Adam sent me the page for the Moon Modular 568 “Sequential Trigger Source” and quipped that it would make a fun iPad app, and I kind of ran with it. (Their site is a frame-a-thon, but ’tis here: http://www.lunar-experience.com/home.html) As you can see, the UI for Phaedra closely follows the Moon Modular design. The functionality diverges quite a bit, though. Once I had the initial look, I just started adding features I personally thought would be nice in a step sequencer. Then the beta testers had some more input. And now that it is out, I’m getting a ton of great feature requests from the users. The next update will have some cool tricks in it, provided I can figure out how to code them.

What hardware would you recommend for connecting MIDI?

The best MIDI I/O situation for Phaedra is an Alesis iO Dock. Hands down. I have tested it with a half dozen MIDI interfaces via the [Apple] Camera Connection Kit [for connecting driverless USB MIDI interfaces], and they all work fine except that $5 cheap one that people buy from Amazon, which unsurprisingly, has problems. Phaedra also automatically creates a virtual port and connects to all virtual endpoints running on the iPad, so it can drive NLog Pro, Animoog, whatever. And it also is [Apple MIDI] Network Session aware, so it can just work over wi-fi.

I’m going to add OSC output as an option in the next update, I think. I’m still thinking about how to implement that, but it seems like it would be handy, and then Phaedra’s abilities would be greatly increased.

I’m also adding trigger outputs via the audio ports, so you can use Phaedra to clock an external modular sequencer like Makenoise René, or a pre-MIDI drum machine. I’m giving it 48-ppq clock for Korg drum machines, 24-ppq clock for most every other drum machine, and arbitrary rates from 16-ppq on up to 1-ppq for driving modular sequencers and your Monotribe. This should be handy, and will be sample-accurate in line with the MIDI clock output.

Some Cool Shit

Numerology is a sophisticated Mac modular step sequencer, capable of brewing patterns from simple to elaborate using combinations of note-making building blocks. It’s also a powerful host, opening up signal routing and modulation to AU plug-ins.

Version 3.1, released this week, may be a “point” release, but its two additions are significant. First, it’ll run as a VST plug-in in any host, which adds direct MIDI routing from plug-in to host. (Somewhere, plug-in developers are nodding, knowingly – AU may be more commonly associated with the Mac, but VST can be a better choice even for Mac users.)

Second, as you can see in the video, you get some tasty new real-time pattern recording modules. Out of the box, they’ll run easily with Novation’s inexpensive Launchpad controller, though you could adapt them to other controllers, too, if you wished. Check out the video to see it all coming together.

Description:

Numerology’s updated Launchpad mapping with realtime pattern recording into the DrumSeq, PolyNote and MonoNote sequencers. The laptop is running Ableton Live with three instances of the Numerology VST, as well as Camel Audio Alchemy for synth lead and NI Massive on pads. The drum sounds are from Numerology’s DrumKit module with a patch designed by Jason Wolf of Tripl3Tone.

All of this is yours in two editions:
Standard (US$129)
Pro (US$199) with multi-output support for hosted Audio Units, OSC support, custom scale quantization, and advanced modules

Thanks to developer James Coker – and glad I can prod him to release videos with these software updates.

More than any technical obstacle, and very often more than any artistic or inspirational challenge, very often the single biggest enemy of music making is time. Finding a way to comfortably develop ideas anywhere, therefore, is a godsend. And some of our favorite artists are the ones who’ve found a way to simply keep producing. Whether it’s a laptop, a gameboy, a manuscript notebook, or indeed an Apple tablet, it’s always nice to see some of the tools that make music creation mobile and inspiration always-accessible.

Chicago-raised, LA-based artist Salva has been lighting up the radar of a lot of DJs, cities, and outlets like Resident Advisor and FACT, and recently was accepted to teach a session be a participant at Red Bull Music Academy. He’s also been lighting up the radar of air traffic controllers — all of that success and endless gigs mean some time on the road. He’s swapped his laptop for an iPad in order to keep writing. Here, we get to watch as Paul Salva constructs music from scratch using Tabletop, a modular creation environment for the iPad.

Check out the step-by-step process in the video at top, as Salva constructs a tune. Found via Prefix Magazine, which notes Salva is appearing alongside the likes of some other artists we love – Sepalcure and Starkey, among others – in an upcoming compilation:

Salva, Sepalcure, Starkey Appear On Frite Nite Comp [Prefix Magazine, an excellent and prolific source of music reporting]

Retronyms, the developers of Tabletop, were naturally excited by what Salva was doing with their software. “We had a good time working with him,” says Retronyms’ Keith Pishnery, “as he gave us a invaluable feedback during the beta stage as well as really pushing the limit of the app in his demo songs. For version 1, he created a custom 808 kit, but has plans to create more sounds for other instruments in a future update.”

Retronyms have also done an interview with Paul on their blog, as well as the video chat here, which elaborates on the step-by-step vid above.

Tabletop Q+A: Salva (Frite Nite/Friends of Friends)

Paul tells CDM a little bit more about what he’s doing:

How’s the iPad fitting into production — or is this just a one-off here?

Paul: As relates to my setup, Tabletop has now become a writing tool for me on the road and at home. I started working with Retronyms on Tabletop a few months back, and the more I worked on it in the development stages, the more I got hooked. I’m working on more content — synth/sample patches, drum machine kits, etc. to offer up for the next round.

Now that I’ve integrated the iPad, TouchOSC is another universally awesome tool which helps me integrate with any midi-ready device that I use alongside Serato and Ableton. For device communication, really stoked about Korg’s WIST technology [wireless "sync-start" used in Korg's iPad apps] as well, which Tabletop utilizes too.

What’s the rest of your rig like?

Like most producers I know, I utilize a hybrid of software and hardware. I love analog synths, but I use a lot of virtual instruments as well. I use Logic and Ableton in my production process for DAWs, a bunch of outboard gear and turntables and mic recording play a big part. My studio is growing with lots of vintage goodies as fast as I’m able to collect!!

Or, as Salva puts it to Retronyms, “Late mornings in bed on the weekend, in the airport, chillin’ on the couch — its nice to have a little portable studio for some creative time.”
