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.

There were quite a few analog synthesizers on hand, including a vintage Serge modular courtesy of Synthesizerman (aka Doug Linner).

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.

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.

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.

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.

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.

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.
