In an explosion of color, buttons, keys, velcro, and fur, and coupled with a cyborg-chic eyepiece, the VoltAxe is controllerism gone Mad Max, a post-acocalyptic keytar bred from salvaged parts. And if you want to make a unique construction of your own, creator Julie Covello – aka New York’s DJ Shakey – is willing to tell all her secrets, as well as why this was important to her music.

In modeling (the basement hobby variety, not the skinny fashionista one), “kitbashing” is the act of combining bits of multiple kits to produce one finished whole. Some custom new controllers are following a similar route, taking the best bits of, say, a keyboard and a Novation Launchpad, and going a bit nuts. Julie’s work deserves special mention not only because it takes that technique to an extreme, but it couples it with a heads-up, hands-free video display to keep feedback from the computer visible without being a distraction.

Julie tells us all the details:

The VoltAxe controller was created as part of my artist-in-residency at the Clocktower Gallery in New York City, made possible with support from the Jerome Foundation. I named my residency “Dj Shakey’s Audio Control Adventure” and wrote a pseudo-blog on Facebook.

To me, exploring Controllerism means trying to make my performance easier, more creative, and more dynamic. I did quite a bit of general research during this project, but with the performance controller, I focused on making a system that allowed me to walk around, not look at the controller, not look at my laptop (remove the barrier between
me and the audience and / or my bandmates), and have maximum flexibility and spontaneity with the sounds I was manipulating.

I had about 5 weeks to work, and I wanted a finished product that I could perform with, so I followed up on simpler solutions and left the hardcore hacking and studying for another time. I was also planning a huge finale party with 23 music and projection artists performing in multiple rooms, so that was on my plate as well.

Here’s a description of the final controller system…
I use Ableton Live — the way I perform, I want to see the laptop screen so I can pick clips at random to suit my mood. I don’t want to memorize my set and I don’t want to stare at my laptop screen either, so the solution was creating an eyepiece that shows my laptop screen within it. To build this I got help from VJ DoctorMojo aka Mark Alan
Johnson of Mojo Video Tech, Inc.. We experimented with a number of hacks, repurposing components extracted from the viewfinders of old camcorders. These experiments yeilded a number of functional miniature low-voltage displays, however these units were all black-and-white and a color image was what I needed. Very long story short, the final solution was to buy a pair of Vuzix
personal video glasses (US$250), flip them upside down and attach ONE screen to a regular pair of glasses so that only one of my eyes is looking at the screen and the other eye is looking out into the world. What I see with both eyes open is my laptop screen floating in the air on top of what I normally see. It’s amazing how easy this is to use!

There was more to do to make this work:
1. I had to run the output of my computer to a scan converter ($100) about the size of a cigarette pack and then run a wire to the little box that manages the glasses, adapters and cables were required.

2. I had to power the glasses, so that meant making the power cable about 10 feet longer so it could be plugged in while I walked around.

3. The image in the glasses was upside-down, since the unit was mounted upside-down (to avoid my nose!), so I rotated it 180 degrees via my Mac OS preferences.

4. The cursor size was too small, so I enlarged it with the Mac’s “Universal Access” preferences.

5. The image of my laptop screen was pretty low resolution, so low that I couldnt read any of the clip names, I referred to the Universal Access preferences to determine key commands for zoom in and zoom out and then programmed
my mouse keys to do the shortcut keys for these functions. Zoom out and I can see levels and stuff; zoom in and I can read type. I also fooled around with the screen resolution so it would be as clear as possible.

Speaking of the mouse, I did more research on the mouse than anything else! I wanted to attach it to my controller, which I was planning on hanging over my shoulders like a keytar. It had to have basic mouse functions AND I wanted buttons that could be programmed to do a series of keystrokes with one touch. There were some pretty cool mice on websites for the handicapped, but they were either absurdly expensive or they didn’t have all the functionality I wanted. I ended up using the one I had on my desk, the Kensington Expert Pro Turbo Trackball. I’ve had several over the years and I love them. They don’t make them any more, so they are hard to get and costly. (US$150 – 300) Also, the trackball is not secured in the socket. I basically just duct-taped this to my controller backing, and secured the trackball (with help from Mojo) with a piece of silver solder and a rubber band so it could move freely but securely. The mouse comes with programming software and I programmed the buttons to do — whatever I wanted!

The controller backing is 3/4 foam board ($5). I need this thing to be light! It is solid and doesn’t flex at all. I attached a number of controllers to this backing, a Novation Launchpad (triggering clips, punching clips in and out), Korg nanoPAD 2 (fx, samples), Korg nanoKONTROL 2 (mixing, fx), and two Vmeters (fx). I also messed around with a Keith McMillen Softstep foot controller which I like a lot and am still incorporating into the set-up. All of these run into a “Plugable”[-brand] 10-input powered USB hub on the back of the unit. I had to add a 12-foot usb extension to reach my laptop, as well as extending the power brick cable. All these long cables were bound into a single cable sleeve running to the laptop and power strip.

In an effort to use the controllers without looking at them, I added textures to many of the keys so I could find them by touch (velcro, rubber, fur). I covered up the keys that I had no plan to use so I wouldn’t hit them by accident. I divided the Launchpad up into 4×4 quandrants with miniature wire and ductape ridges. I’m still adapting to this set-up.

After the whole thing was put together, I hung it from a strap I grabbed off a gear case I had in the room. It took some trial and error to determine where to place the ends of the straps on the controller so that it would hang properly and my hands reached all the controls comfortably. I spent some time with the prototype attaching and re-attaching items until everything was in the right place before cutting out the foam board into the final shape. At this time, everything is attached with checkered duct tape from Home Depot; soon I will upgrade this to velcro (but keep the checkers as
decoration!).

The VoltAxe was ready to test play at midnight the day before the huge event where I was going to perform! Thanks to
Moldover and Mojo, who were with me doing ongoing troubleshooting, configuring went quickly and I was able to rehearse for a few hours and pull it together just in time! At the show, everything went as planned and I couldn’t have been happier – it was
so much fun! I can’t wait to evolve this set-up! My next move is to make it mobile and take it to the subway station to do some busking.

Thanks, Julie!

Cheap, ultra-slim, and easy to pop in a backpack, Korg’s nano Series were a big hit. The only real blemish on this line has to be the original nanoKEY; some people managed to use it, but key caps chronically fell off and it wasn’t a whole lot of fun to play. The nanoPAD and nanoKONTROL fared much better, providing pads and faders in a laptop-ready form factor. And since they don’t require drivers, these will also work with new devices like the iPad.

With the nanoSERIES2, Korg mainly sticks with the original formula, but adds a few adjustments. They have the same housing, says Korg, and driver-free USB operation. So what’s new?

• nanoKEY2: A new keybed, “modeled after a MacBook.” So, it is still going to feel like a computer keyboard (a necessary evil given how thin it is), but at least it’ll feel like a better keyboard.
• nanoKEY2: Light-up octave shift.
• nanoPAD2: Record gestures on the X-Y pad.
• nanoPAD2: 16 pads instead of 12.
• nanoPAD2: Arpeggiator, chord triggers.
• nanoKONTROL2: 8 faders instead of 9, and a more logical control layout.
• nanoKONTROL2: Mackie HUI support.

I’m especially excited by the nanoPAD2, as it gets quite a significant improvement. All in all, these look subtly different but improved, particularly in moving the nanoKEY2 into the realm of actual usabilty. Pricing remains the same; stay tuned for these to ship.

nanoSERIES2

And yes, they’ll still be available in white, though now with a more subdued color scheme (none of the retro blue-and-white flair). See below…

Compact MIDI controllers for your fingers are plentiful, but tiny foot controllers are far fewer. map~map aka Marcus Fischer decided to build his own by performing a simple but clever mod of the KORG nanoKEY. Now, personally, I find the nanoKEY the one product in the nano series that’s lacking; it feels more like a QWERTY keyboard than anything resembling a MIDI keyboard. But Marcus transforms it into the world’s most compact and portable foot controller. You may have to be somewhat delicate with your toes, but he says the solution works perfectly!

i’ve been wanting a compact usb midi foot pedal for a long time. i built one out of a usb number pad last year but it was less than ideal. tonight i popped all of the keys but five off of my korg nanokey in order to see how it would work as a pedal. it turned out that it worked really well. i cut some small pieces of plywood out to raise the key height and some scrap plexiglass to cover up the missing keys. a little spray paint and double stick tape and it was all finished.
i think it turned out pretty well. not bad for a cheap keyboard and scrap materials.

Those wooden blocks look quite lovely. KORG, you may have inadvertently created a new product.

Getting handy with the $60 KORG Nano Series controllers and Ableton Live keeps getting more sophisticated. I did a "quick hack" using the text-based MIDI Remote Scripts with the nano as an example, and provided a download. Next, Raymond Weitekamp modified those scripts and added a monome for a full-blown Live performance. But now James Waterworth aka Myralfur takes the whole idea to the next level, with a fully custom set of scripts with control of additional channels, more control over tracks, and most importantly, interactive scene triggers.

I’ve built a custom python script for the nanoKontrol based on the hacked python scripts for the Axiom controller decompyled from live 7. It adds the ability to switch up to controlling channels 9-16 by changing midi channel (or changing up to scene 2 on the nanokontrol, which I had sending out on midi channel 2 instead of 1). It also has track on/off, solo/cue, panning, and also has the bottom row of buttons triggering clips on the relevant track, with forward and reverse skipping up and down scenes, and the loop button triggering the selected scene.

Best of all, you really don’t need to know – ahem – what you’re doing with scripting to make this work. Just follow the instructions below, and you’re ready to play – so you can get back to your set.

Now, James has polished off the script and fixed compatibility with Ableton Live 8, and this is ready for public testing. Give it a go and let us know what you think. I’ll work on a permanent home for all of this stuff, but for now, let’s just use comments for any issues. For some insane sounds, be sure to check out Myralfur’s music and DJ mixes on Soundcloud, too! He’s working on a rig that also incorporates a Sony PlayStation 3 controller.

nanoKONTROLMyr

A midi remote script for use with Ableton Live 8 and the Korg nanoKontrol.

Set-Up

1. Download and Unzip the file.

2. Move the nanoKONTROLMyr folder to the MidiRemoteScript folder within your Ableton Live application folder.

3. Open your Korg nano series editor and load the presets within the NanoKontrol Presets folder, over-writing your previous settings.

4. Select nanoKONTROLMyr as a control surface in the midi pane of the preferences window.

Mappings

Banks

Bank 1 controls tracks 1 – 8

Bank 2 controls tracks 9 – 16

Bank 3 maps the encoders to the selected device and provides functions for moving tracks and devices.

Bank 4 is free for mapping to whatever you like, sending on midi channel 4.

Global

The Ninth Slider is Always mapped to Master Volume, regardless of bank or midi channel.

The Ninth Encoder is Always mapped to Cue Volume, regardless of bank or midi channel.

Transport

Transport functions only work when receiving midi cc numbers on channel 16.

Different functions are called when in session view and arranger view for some of the buttons. The Loop button acts as a Shift to allow more functions to be called with the other transport buttons.

Loop = Shift

Play = Play (Scene Launch when Shift held)

Stop = Stop (Stop All Clips when Shift held)

Record = Record (Overdub On/Off when Shift held)

Session Specific

Rewind = Scene Up (Scene Up by 5 when Shift held)

Forward = Scene Down (Scene Down by 5 when Shift held)

Arranger Specific

Rewind = Cue Position Left

Forward = Cue Position Right

Encoders

The Encoders map to the Pans of the tracks. When sent on different midi channel numbers they map to different tracks. Channel 1 maps to tracks 1 – 8 and Channel 2 maps to 9 – 16 etc.

When sent on midi channel 16 they map to the selected device. This works in conjunction with the pads and buttons sending on channel 16 which provide functions for moving track and controlling devices.

Sliders

The Sliders map to the Volumes of the tracks. The tracks they are mapped to changes with the midi channel they are sent on. Channel 1 maps to tracks 1 – 8 and Channel 2 maps to 9 – 16 etc.

There is as yet no function for when they are sent on channel 16.

Top Row of Buttons

The buttons on the top row turn Tracks On/Off. The Ninth Button on the row acts as a Shift and when this is held the other buttons Record Arm the tracks. They function the same as the sliders and encoders in that they map to tracks depending on the midi channel.

However, when sent on midi channel 16 the buttons select and view tracks 1 – 8 mapping the encoders above to the first device in that track.

Bottom Row of Bottons/Pads

The buttons, or pads, on the bottom row Trigger Clips. The Ninth Button on the row acts as a Shift and when this is held the other buttons Stop the relevant clips. They function the same as the sliders, encoders and top row of buttons in that they map to tracks depending on the midi channel.

However, when sent on midi channel 16 the buttons provide various functions for controlling devices.

Button 10 = Track Left

Button 11 = Track Right

Button 12 = Device Left

Button 13 = Device Right

Button 14 = Bank 1

Button 15 = Bank 2

Button 16 = Device On/Off

Button 17 = Clip View/Device View
