The Covert Seq – Creating patterns and Presets from Bjorn Vayner on Vimeo.

The Covert Operators and Bjorn Vayner have become my favorite go-to source for wild Ableton Live hacks. And even before the release of Max for Live, Bjorn has built some terrific, simple step-sequencers using Live’s Racks feature. That’s just the Racks feature – no Max patches or hidden features anywhere to be found. Sure, I suppose the clip view itself can be seen as a kind of step sequencer, but this gives you a unique way of generating sequences.

If you just want to begin playing with step sequencing in Live, Bjorn has a new download, aptly called The Covert Sequencer, as seen in the video at top. It’s free, it’s fun, it celebrates the 5th Anniversary of Covert Ops and the 10th of Ableton Live (good grief!), and it’s all voodoo built with dummy clips and MIDI effects.

If you want to try your hand at the ninja skills behind all of this, Bjorn posted a screencast back in August revealing his secrets:

And if you like this sort of thing, definitely don’t miss The Covert Operators’ exclusive creation for CDM, making elaborate use of the racks and slicing features of Live 7 and later:

What happens when you put all the digital and electronic tools you love together into one groove session? I expect it probably looks something like this video. Welcome to the new digital music age: DIY electronics, vintage digital tech (Game Boys), and modern computer tech (Monome as Arduinome clone, Max/MSP, and shiny MacBook) all coexist. And a fair bit of what you see if a modern hybrid of old and new paradigms, like the thoroughly modernized Tracker Renoise. Thomas Margolf says “Greetings from Rotterdam” and writes,

We made a first Jam using the new GorF step-sequencer, Arduinome, max msp patch ‘Soyuz’, a Gameboy running LittleSoundDJ, LSDJMC2 Gameboy Midi-Interface, Renoise, Ableton Live and a Nord Micro-Modular. It’s the first session with a fresh soldered GorF.

Lovely stuff. Keep on soldering and jammin’, folks. Okay, tagging this story is going to take … a lot of tags.

I ask you: what is the foundation for rhythmic electronic music? I suggest that the humble step-sequencer is the backbone of many of today’s musical genres and memetic evolutions. To have electronic rhythm, you need to start with a clock and go from there, dividing it into fractions and multiples. Then start assigning sounds to those divisions and you’re pretty much there- techno is happening.

I’ve been working on prototyping a sequencer-synth and in doing research, I’ve come across numerous projects that tackle this idea with great enthusiasm. Because a sequencer can drive any type of electronics, projects tend to fall into two categories: audio, or visual. Additionally, I’m seeing two main drivers for the sequence itself: the nimble arduino, and the CMOS 4017 Decade counter IC. I’ll survey here some of the finished projects to give an idea of what’s possible. Come with me, won’t you, on an exploration of the world of DIY sequencers.

First up, a few excellent audio sequencers:

basic arduino sequencer from nikolaosh on Vimeo.

This “basic arduino sequencer” by Nikolaosh is undeniably fun. Looks like four potentiometers controlling software synth parameters, with the Arduino doing the sequencing as well. Basic, but effective nonetheless. You can see more details and grab the code here.

BeatSequencer 1.0 from Kamil Garbacz on Vimeo.

This “Beatsequencer” by Kamil Garbacz also uses Arduino to drive a matrix of LEDs. Looks like the top row indicates the position of the step, while the bottom 3 rows indicate on/off status for the beep assigned to that row. A matrix of switches turns each step on and off, 808-style. It’s a very compact design with a minimal interface, but it seems to work.

cigarduino punk console from frogstar on Vimeo.

This “Cigarduino Punk Console” from frogstar has a lot of great elements- nice pulsewave synthesis from the Arduino and a fun cigar-box case. It’s a little light on the LEDs though- don’t we all like our sequencers to have big banks of LEDs pusling through their paces?

In the 4017 category, we’ve got this nice little box from Note!. It nicely marries the Atari Punk console to the 4017 running as a 4-step sequencer. Good glitchy tones get put through their paces.

This sequencer from 9volts really opens up the possibilities here- he’s using the 4017 synched to a drum sampler, triggering circuit-bent devices and controlling gating and filtering. That’s what I’m talkin’ about right there.

Visual sequences:

PAN PC + 555 + 4017 from h.cosas on Vimeo.

This experiment from h.cosas uses the 4017 to drive an LCD display with interesting results. Dig those color bars!

This LED pattern sequencer by WootsPC is very nice to look at- this should give you an idea of what can be done with a basic sequencer, some LEDs, and an eye for animation.

What I take away from all of these projects is the idea that a sequencer can drive pretty much anything, and the most fun and interesting projects lie not in the sequencer itself, but in what is driven by the sequencer.

I’d really like to see someone who combines these LED animations with a good sounding, nicely-interfaced sequenced synth that’s syncable to MIDI clock input, but I think I might have to build that one myself- I’m working on my own like-minded project, and I’ve realized I’ve got a ways to go before I’ll be satisfied with the results. In case you’re curious, here’s my little project as of two weeks ago. I’ve made some modifications since then, but you get the basic idea.

Is anyone else working on a sequencer project? Please post it in the comments and tell us what how it’s coming along.

You buy a box. You unwrap the box. You plug it in. You read the manual to learn what it does. Or you bring a box home, and meanwhile a community of people – possibly including you – works to imagine new possibilities for what the box can do and share them with each other. It’s clear that the idea of open hardware (free hardware?) has a lot of potential. But it’s a matter of finding products that realize that vision. And today alone, I’ve got a lot of good news on that front.

There’s some wonderfully good news for fans of DIY music tech. And the homebrewed, open, hackable tools often outshine commercially-available options. For developers, they’re a change to hack on something, but they serve as end-user products, too. The GorF step sequencer and minicommand — the latter tough to describe but a sort of do-everything magical box o’ MIDI — are each nearing shipment, complete with preorders. And the folks at BUG Labs have added sound capabilities, which is already turning into some interesting prototypes of alternative mobile music devices.

Back-to-Basics, DIY Step Sequencer Kit

The GorF step sequencer appeared in a video demo a few weeks ago. But if you were intrigued by the YouTube rendition of GorF, the time to get your own is nearing. PCBs have arrived and, in a DIY Valentine’s Day present, there’s a poll about interest.

Black Box Performer

GorF is impressive, and I like its elegant, simple step interface. But the tool that’s been really blowing my mind is the minicommand. At first, it looks like just a simple, compact controller – nice knobs, and a screen you can customize. That’s all well and good. But the minicommand is better understood as a do-everything, magical black box. Programmable with the Arduino environment, the minicommand can become a controller, an arpeggiator, a Euclidian polyrhythm maker… out of the box, it’ll already have a ton of firmware tools, alone. Maker wesen writes:

- standard midi controller firmware
- machinedrum notes (hook up a keyboard to the machinedrum). The device has an additional MIDI IN for that kind of purposes
- monomachine firmware (revert to kit, etc…)
- supatrigga for the machinedrum
- genetic patch mutation firmware for machiinedrum and monomachine
- polyrhythmic sequencer (with MIDI CLOCK slave or master function)
- arpeggiator
- much more…

It’s like what a lot of people do with Max or AudioMulch patches, but in a hardware box, with tight timing, that you can either plug into your computer or into hardware synths. It’s like MIDI hardware for the year 2009. You might wind up just using it as a reliable clock source for your software with hardware controls, or you might drive hardware with it, or you might control visuals – it’ll become whatever you like.

Oh, and by the way, while the Akai APC is cool, I’d love to see an ultra-compact setup with one of the minicommands and perhaps a Faderfox or two. Time to dust off your 5-pin MIDI cables, huh?

Hack-a-Pod: BUGsound

At the opposite end of the spectrum, the folks at BUG Labs have added a sound input/output module to their hot-swappable, LEGO-esque modular mobile gadgets. The BUG is basically a modular computer that runs an open source OS and Java stack and is pretty intelligent about talking to sensors and the Web. As readers have noted, it’s not cheap, but I think it’s best understood as a prototyping device. As such, it has some competition from even devices like Google’s Android, but with a key difference: you have total control over the OS and the hardware you plug in. So, Android may also have GPS, but it doesn’t have audio input, or the ability to connect sensors or servos via bare wires, and you probably don’t want to take your 2-year-contract phone and strap it to a mobile robot.

Why prototype mobile devices? Because it becomes possible to imagine just how interesting mobile gadgets in the future could be. Instead of passive devices for consuming approved content (cough, iTunes), they become open-ended, handheld computers that do whatever you like.

And that could mean you could also prototype musical instruments with the flexibility of computers, instead of the closed-box, commercial options we have now.

BUGsound Available Today

BUGsound isn’t quite high-fidelity: the internal speaker is a simple mono speaker, though at least it makes noise, and there’s a simple, built-in electret condenser mic. But it can drive headphones, it has stereo input and output, controllable gain, and even automatic gain control. Where it gets interesting is that you can combine these features with other modules, like the accelerometer or GPS, for mashed-up gadgets. And there are some simple DSP-based sound functions on the board, too.

I’m finally blocking aside some time to work with BUGsound myself, but there’s already a cool demo app from the community called Phunky. It mixes three sound files using accelerometer data. This also demonstrates why we need to get more robust sound-crunching capabilities going (Pd, perhaps) so the applications can get more interesting.

I’m really excited about all three projects. You know where to stay tuned for more. And by the way, we might just have some new ways of covering these kinds of projects and helping folks collaborate … soon.

The creator of the wonderful glitchDS, repeaterDS, and cellDS Nintendo homebrew music apps has turned his sights to the free and open coding-for-artists desktop tool Processing. The result: a drum machine that mutates and morphs in wonderful ways via a command-line interface. (I almost put the command line bit in the headline, but while I actually adore command lines, I think the more interesting part of it is the way it mutates its patterns in lovely ways. No boring endless step sequence repeat here.)

The tool is called Quotile, and since it is built in Processing and the code is entirely free, you’re welcome to try it out and change it around if you like! Apparently the Mac camp are having some troubles, but I don’t see any reason it shouldn’t work on Mac; the problem is generally that getting Java MIDI running on Mac has some tricky bits because Apple dropped support for the Java MIDI API, even though it’s a standard part of the Java platform. In this case, I expect it’s the library’s reliance on mmj or people having trouble installing that MIDI subsystem that’s the culprit. Keep the faith: it can work, and I hope we can get a standard, reliable MIDI library soon.

The sound source above: Machinedrum, of course.

I’ll give this a try on Linux later today, on the platform that I think has the best MIDI support, hands-down – yes, even compared to the Mac. (I’ll explain why I think that soon.)

Speaking of MIDI libraries, the Processing library this is based on is a new one called MIDI Bus. It’s very similar to wesen’s rwmidi, which we’ve covered before.

Forget NAMM — one of a handful of hardware I’m most excited about in 2009 is all DIY, the 8-step GorF step sequencer. (I’m hoping for follow-ups like a Forg or Grof. Kermit (Muppet) fans know what I’m talking about.)

With four sequences with parameters, steps with pitch, gate, and Control Change, sequencing controls, legato mode, and the planned ability to both send and receive clock, this is one useful-looking device. And from the video above, it looks like it’s progressing really nicely.

In fact, if you think about it, it’s kind of puzzling that there isn’t a simple, cheap, commercial device that does this. As a kit, though, people could hack in features others might not imagine, it could be combined with other DIY and open source synth and music projects, and it makes a great kit and learning tool — meaning it’s more fun, anyway. And if you want a pink case, you can do that, too, but you can decide whether you want it more salmon or fuchsia.

Paul, do keep us posted!

Sequencing – the collection of techniques that actually assemble events in our music – seems to get far less attention than it deserves. After all, there are fairly accepted ways of synthesizing sound, but as many ways of thinking about musical events as there are ways of thinking about composition. Among the big DAWs, you’ll often see pitches to upgrade based on new effects plug-ins or magical audio-processing abilities, but rarely MIDI sequencing improvements. (When there are, of course, I applaud.)

That makes this week’s pre-Christmas announcement of Numerology 2.0 all that more special. Numerology is a modular sequencer and that alone. It brings some of the modular capabilities usually found in synths to sequencing, with component sequencers and modulation for manipulating sequence evens the way you’d usually transform sound signal.

The upshot of all of this: you can play with musical patterns with the freedom usually reserved for synths. Features:

• Sequencing modules, including MonoNote (monophonic sequencer), polyphonic PolyNote (duh) and MatrixSeq, eight-track DrumSeq
• Component sequencers for modular-style sequencing, plus LFOs, envelopes, CV mixers, MIDI generators, MIDI processors
• Stacks: virtual equipment racks for easier composing / performance, and an integrated audio mixer
• Add software plug-ins (AU) or route to external hardware gear (yep, the computer is still awesome when it comes to sequencing outboard synths, even in 2008/9!)
• New, simple sound-generating modules for easy integration with the environment, including synthesis, polyphonic AudioSample and eight-part DrumKit
• MIDI remote control of parameters, plus custom CV, audio, and MIDI routing
• Timeline playlist arrangement
• Sync via MIDI clock, MTC, or ReWire
• Mac-only, 10.4.11 and later; US$99 until 1/4/09 (then $119)

System requirements are pretty tame (this is a sequencer, after all), so this could be a great application for an older Mac, provided it has a 1GHz or greater CPU. (PowerPCs included.)

How does it all work? Here are some videos to give you an idea. Hope to add this to my scary but delicious testing pile (New Years’ Resolution: more useful hands-on content).

A demo:

Getting started:

Any passionate Numerology users out there? We’d love to hear from you. What are your thoughts on the new version, and how do you use the tool in your music?

Here’s something I’d very much like to see: a hackable, kit step sequencer.

nostromo tips us off to a blog item on his site on the project. The creation of Monowave maker Paul Maddox, the 8-step sequencer is based on an Atmel Mega16 micro chip. The whole thing is looking very compact, which could make a nice little unit or might integrate well with other projects (like a synth).

The other good news to me: new DIY hardware could be a great way to run clock into software. Previously, that job has fallen to somewhat dull consumer drum machines. With DIY projects, even software lovers may soon be hacking new features into hardware and manipulating software sequences with that.

Planned features include “rock-solid timing” (sounds good), plus:

• 4 sequences with parameters
• Steps with pitch, velocity, gate on/off, and two Control Change messages (CC1/CC2) on a selectable channel
• Adjust tempo, base note (including via MIDI), sequence and step length
• Legato mode
• Send MIDI clock out, MIDI sync in (currently input isn’t done – input is usually trickier than output, but output may actually be more interesting to people)

nostromo already has some ideas for how to make this interesting when combined with chip trackers like LSDJ and LPGT, so worth reading his original post (thanks!):

Anyone out there worked on a similar project? (I’d sure love to have a DIY sequencer or two at our Handmade Music events in NYC!)

Here’s what it looks like in action:

Download and explanation of how to use it:

Introducing Frankenloop: Free Reaktor-Powered Step Sequencer with a Twist

Peter will be revisiting how the tool was put together and how you might use it in Kore in future episodes stay tuned.

We’ve had some running themes going on the site in the past few weeks.

I’ve been talking about Kore for sound design and performance:

Sound Design for Imaginary Instruments: Kore, Guitar Rig

Sound Design for Imaginary Instruments: A Kore-Prepared Piano

Sound Design for Imaginary Instruments: The Results

How to Control Reaktor Patch Parameters with Kore

Kore: The CPU-Saving Power of X in Live Performance

That reflects for me the appeal of Kore in my work, which is to use it as a meta-instrument for shaping and playing sound. I got to play my first gig with just Kore — Reaktor stood in for Live. (I expect I’ll bring Ableton back into it, but it was fun to do.)

… and Peter Dines has (at my urging) been gradually building up some resources for learning Reaktor patching, with a couple of additions from me:

Mutek Interview: Exploring the Reaktor User Library with Fennesz

Revving up Reaktor: A Refresher on Clocks and Events

Next Steps with Reaktor: Tutorial Review

Tim Exile: Reaktor Video Master Class/Demo

We’ll keep developing these themes. Over the coming weeks, looking at what we have slated, I think we’ll have a sort of live, online manual for these tools. We really do welcome your feedback — and I have to say, I’m really pleased to have heard from you as this is a new idea. I’m learning a lot from it. Now if you’ll excuse me, back to hacking.

Hope this gives you something to play with over the weekend, Reaktor and Kore users — it definitely does for me. Now I just need some rainy weather that encourages me to stay in and work on it…

Mobile music suites date back to the first PDAs; the Palm has long been a stand-out platform with apps like Chocopoolp’s wonderful Bhajis Loops. The iPod Touch and iPhone have been a hotbed for development, thanks to sharing development frameworks with the Mac. That led our iPod/iPhone software round-up to be bursting with good stuff. But lacking a final SDK from Apple, many of the options were, admittedly, early in development or toy-like.

Intua’s new BeatMaker, a complete music studio, looks more like a real music tool. The basic functionality:

• Mobile sampler: 16 pads for editable sample playback, slicing, and pattern recording. (I hoped this meant you could actually record on the fly, but it looks like you can’t.)
• Step sequencer with an interesting-looking interface, pictured above
• Effects: two channels with beat-synced delay, 3-band EQ, and bit-crushing distortion

Intua Product Page

We’ll be watching for news from Apple this week, which should give us a better sense, hopefully, of what Apple’s developer plans are. To me, the restrictions so far (limiting features, eliminating multi-tasking, and requiring distribution via official Apple outlets) dampen some of the appeal of the platform. Likewise, so far we’ve seen basically “hacked” development – and quite frankly, it’s been more interesting as a result. We should know soon more about what officially-sanctioned development will look like for music. BeatMaker could be one of the first generation of apps to fit that category.

And lest I just seem sour, to me the larger point is that OSes come and go; what we’re really seeing is richer capabilities on mobile devices. Apple certainly deserves credit for making that vision most apparent in a shipping device.
