Report from BPOW!!! Part 2: The Concerts

Today we conclude our reports from the Battery Powered Orchestra Workshop (BPOW!!!) in Portland, focusing on the evening concerts. Like the workshops, which we covered in Part 1, the concerts focused on DIY technologies, as well as analog synthesis.

The Saturday-evening program opened with Stephanie Simek performing on her custom multi-armed turntable.

20130810-IMG_9779

The arms on the turntable were outfitted with contact microphones which picked up vibrations from the grooves of hand-cut records. Each arm fed a separate audio channel, creating a multi-track, spatialized performance from a single record. Musically, the repeated sounds of jungles, space, human activity and instrumental sources formed complex rhythms with changing syncopations and graduation motion over time. The effect was quite hypnotic. Even with the enveloping sound system, there was something intimate about the performance, probably related to the visuals and distinct sound of the record player.

Simek was followed by F-DT (Future Death Toll). F-DT is an artist collective and performances feature a rotating lineup, but on this occasion it included Edward Sharp and Nathanael Thayer Moss. F-DT describe themselves as “a throbbing mess of noise that eats technology and shits performance art.” And it was certainly a performance filled with loud noise in a variety of aural ranges – high electrical noises and pounding low-frequency patterns – set against a relentless stream of glitchy visuals and text.

Although it is hard to tell from this photo, much of their gear was colored orange, which seems to be an important part of the group’s identity. The music and presents is undeniably challenging, but well worth for those who make the effort.

Then it was my turn to take the stage. My setup focused on the analog modular synthesizer, along with another analog synth, iPad, the dotara (Indian string instrument), and Skatch Box. I also used the Synthrotek 4093 NAND synthesizer that I built during one of the workshops earlier in the day.

The 4093 worked flawlessly, as did the modular and the Luna NT analog synth. The acoustic instruments (dotara and skatch box) also worked well. As with any experimental electronic improvisation performance, there were a few technical glitches and a few things I would have done differently in hindsight. But overall, I thought it was a good performance, and it was very well received by the attendees. You can see and hear it in its entirety in the video below:

The final act of the first night was Mechlo. His performance combined lo-fi glitch audio and video from an NES console.

20130810-_MG_9785

Clearly, there were modifications made to allow the system to be performed in a way that a traditional NES could not. Nonetheless, the graphics and audio were reminiscent of what one would expect from the classic 8-bit games. There were repeated modulating patterns, some of them more melodic, some noisier, with occasional glitches and pauses.


The Sunday evening concert opened with a performance by analog modular virtuoso Jeph Nor with Dan Green on analog video. Green brought an LZX modular video system, while Nor had a large collection of audio modules from different manufacturers.

Nor built complex patterns of sound that went from sparse and resonant to thicker and more pad-like. There were moments of eerie ambience and others that had a machine-like precision. Overall, he was able to give his improvisation with this instrument a musical and even narrative quality. The visuals focused on patterns of colors, curves and lines that were constantly changing, but occasionally slowing to a standstill before shifting rapidly and switching to a completely separate collection of shapes.

Next was Mike Todd performing custom visuals and sounds. Unlike the sharper edges from Nor and Green earlier, or the noisy intensity from F-DT the day earlier, Todd’s performance was software and more organic. The visuals, based on his own software, were composed of curving liquidy shapes that seemed alive. Similarly, his music had an equally liquid quality, with more open space between fast elements, as if a swarm of moving organisms.

20130811-IMG_8673

Todd was followed by JMEJ, who assembled sonic circuits live on stage. One can think of this as “analog live coding”.

20130811-IMG_8676

The process was fun to watch. As one might expect, the sounds were a bit on the noisier and unpredictable side, but with a lot of good crunchy lo-fi texture. As the performance continued, the circuits grew more complex and culminated in this tangled product:

20130811-IMG_8678

The final performance featured Claus Muzak performing some of his electronic-music compositions.

20130811-IMG_8680

This was a more structured performance, divided into songs. His music had a strong rhythmic and harmonic foundation, realized with a diverse collection of synthesizer and drum-machine sounds. It was dark and richly textured, and at times danceable, especially when he employed rhythmic lines with high-Q filters. It was probably the most “traditional” of any of the performances on either night, well crafted electronic music that would be at home in a club setting. But it was a fitting conclusion for evening’s performances and for the festival as a whole.


You can see and hear brief excerpts from all the performances in this video:

BPOW!!! Battery Powered Orchestra Workshop – Aug 10-11, 2013 from Molecule Synth on Vimeo.

Overall, both the concerts and workshops from BPOW were a rewarding experience. It would be great to visit again to participate in future events, and in the meantime I look forward to hearing more from the artists involved. Thanks to Travis Feldman of moleculesynth for organizing BPOW and Myles de Bastion of Cymaspace for hosting.

Report from BPOW!!! Part 1: The Workshops

It’s been a little over a week since the Battery Powered Orchestra Workshop (BPOW!!!) occurred in Portland. Today we look back at the workshops, which were in many ways the central components of weekend.

During the Saturday morning session, I attended a workshop on electronic textiles hosted by Cat Poole of Cacophonous Creations. The skill was to learn how to use conductive thread to embed both light and controls into clothing for future performances. But for the workshop, the task was to simply sew an LED and its associated circuit onto a dinosaur patch:

BPOW electronic textiles

Of course, we at CatSynth approve of Cacophonous Creations’ chat noir logo! As for the task itself, the biggest challenges related to general sewing and laying out elements to properly fit (at least for someone with little sewing experience beyond repairing buttons). But I got through the threading of the circuit. It would be great to incorporate something like this into costuming for future performances.

In the afternoon, I attended a session presented by Steve Harmon of Synthrotek. It centered around DIY electronics and the ubiquitous 555 integrated circuit. But that then merely building an Atari Punk Console with a 555, we stepped it up with Synthrotek’s 4093 NAND Synthesizer.

4093 NAND Synth kit

The 4093 includes three square waves, based on a dual 556 integrated circuit. I was quite intent to complete it and be able to use it for my performance that evening. The soldering of the components went quite smoothly – it helps to both see other people soldering and to have access to a good iron. It was a quite a rewarding moment when the synth was complete and making sound.

Completed 4093 NAND Synth

My only disappointment was the pots not quite fitting and ending up a bit lopsided. But it worked great in the performance and will certainly be used again in the future. The additional confidence on soldering will also be valuable for future projects.

Additional workshops in the afternoon included an introduction and demonstration of modular synthesizers by Jeph Nor. He demystified modular for a general audience by presenting the fundaments (oscillators, filters, amplifiers) and adding additional elements.

Attending all the workshops on Saturday would have been impossible, especially if one wanted to complete the associated tasks. In particular, I was also interested in the Raspberry Pi which was presented by Edward Sharp.


Sunday’s workshop sessions opened with a demonstration of “squishy circuits”. It turns out that homemade play-doh is quite a good conductor of electricity, and can be used to quickly prototype circuit ideas. It also serves as a very accessible medium for introducing principles of electronics to children.

We also got to see other non-traditional conductive media including ink and paint that can be used to integrate electronics into artwork without the use of wires.

Then everyone scattered for an electronics scavenger hunt to find electronic toys and various media to use in projects during the afternoon. The participants reconvened later in the day and got to work.

Our host Travis Feldman of Molecule Synth hacked the interior of an Atari console with both audio and video modifications, attaching it to a Moog pedal.

Other creations included a circuit-bent toy keytar and a tactile surface used to control audio and video on a laptop.

Overall, the workshops at BPOW were a rewarding experience. In addition to new inspiration and a few new skills, I liked seeing the wide variety of interests and disciplines that others brought to creative DIY electronics for music, video and performance art. If the event does recur next year, it will be interesting to see how technologies and the skills of participants have further evolved.

In addition to the workshops, BPOW also featured performances in the evening. We will look at those in a subsequent article.

Outsound Music Summit: Touch the Gear Expo

The 12th Annual Outsound Music Summit began this past Sunday, opening as always with the Touch the Gear Expo. Musicians and sound artists from the Bay Area and beyond were on hand with their musical devices and inventions for the public to observe and try out. I participated this year with two technological extremes: soft synths on an iPad, and a full two rows of Eurorack format analog modules.

Both offerings were quite popular, eliciting curiosity from visitors of all ages.

One of the more intriguing analog synths I encountered was this creation by Andy Puls.

The circular pattern represents a step sequencer controlling an internal sound generator. Conductive pegs can be moved around on the bars to change pitches and other parameters. There are also knobs as well. The overall geometry, control design and lights made this a visually appealing instrument.

Nick Wang also demonstrated some custom analog boxes with controllers, oscillators and a VCF.

Fernando Lopez-Lezcano demonstrated his elaborate homemade analog synthesizer. I have had the privilege of hearing him play it in a formal performance.

Matt Davignon demonstrated his devices for working with fixed-media sources, a bit of a preview of what we can expect for Friday night’s PMOCOTAT performance.

20130721-IMG_8408

Acoustic creations, in particular sounds from natural sources, were a common theme this year as well. Cheryl Leonard demonstrated her expertly tuned instruments made from stones, bones, shells and wood gathered at the extremes of the earth. She also demonstrated her virtuosity with using these elements together, such as generating rhythms from a series of bones passed over the shells.

David Samas was also on hand with his musical creations from natural sources found here in northern California.

20130721-IMG_8422

Missing from the picture above is his tuned aluminum rod, from which one can get quite a powerful sound with a well-rosined hand. I had the opportunity to try it out myself.

Bryan Day presented his instruments made from found objects, including the tape measures featured prominently in the image below. Other sources included springs and metal rods. His creations are quite ergonomic and easily to play, putting unusual sources into compact and intuitive arrangements.

20130721-IMG_8413

Horaflora combined acoustics and small electronics in a couple of lively offerings, including drum heads excited by magnets. I heard him play this in a program several months ago.

20130721-IMG_8414

Horaflora also demonstrated exciting natural acoustic elements atop a subwoofer connected to an iPhone synth. You can see and hear a bit of my attempting to demonstrate these elements together with him in the following video:


David Molina (aka “Transient”) also blended acoustic and electronic ideas. He had a variety of small instruments and sound sources on hand, which he used to generate source material for complex loops and textures controlled in real time via Albeton live.

20130721-IMG_8419

In his own words, this was only “about half of what he will be using in his performance on Friday.”

Tom Nunn, a prolific inventor whom I interviewed in 2012, was once again presenting his creations. This time it was an exceptionally colorful set of his Skatchboxes.

There were others presenting as well, and unfortunately, I did not have time to see everyone and also attend to me own station. But I hope to see more of all the participants in more musical settings.

The Outsound Music Summit continues on Wednesday night with the first of the formal concerts, you can see a full schedule here. And of course, you can always follow along with @catsynth on Twitter if you can’t attend in person.

CatSynth pic: Mandarina and modules

From Travis Johns via the CatSynth Facebook page.

Mandarina “assisting” with some modules – March is the hottest month in Costa Rica and my studio is on the second floor of a building with a metal roof so daytime temperatures render it unusable – so I’ve been bringing work home with me in order to work at night when the temp’s a little more bearable. Unfortunately, there’s usually a certain orange snag to that plan. The modules themselves are from a class I’m teaching called TicoTronics – teaching basic electronics and circuit design via open source synth schematics, modified to use only components common to Costa Rica.
