Cappuccino Synth Video Via CDM

Posted on August 26, 2010 by John C.S. Keston

I first saw this on Create Digital Music a few days ago, and although I think most ACB readers keep well abreast of what’s up on CDM, I’ve watched this several times now and think it deserves a re-post here. For more about this video visit the original post.

Experimental guitarists have been doing similar things like holding power tools or more recently, mobile phones, up to their pickups to generate interesting sounds. Here’s a video I shot of Siamese Bug a duet of Tim Glenn on drums with contact mics, and Jeremy Ylvisaker on prepared guitar.

Experimental Music Mondays #6

Posted on July 16, 2010 by John C.S. Keston

This round of Experimental Music Mondays features Stuart DeVaan from Savage Aural Hotbed, Davis-Glenn-Keston (Jon Davis, Tim Glenn, and John Keston), and Ostracon (John Keston and Graham O’Brien). Usually the last Monday of the month, this instance has been bumped up this Monday, July 19, 2010 where you will find us at the Kitty Cat Klub in Minneapolis, Minnesota. Expect to receive a brain-full of beautiful, grating, mysterious, haunting, mechanical, and organic sounds.

Ever Wonder What it Would be Like to Draw Sound?

Posted on July 14, 2010 by John C.S. Keston

I’m working on a MaxMSP performance patch that uses a Wacom tablet to draw light onto dancers holding light sensitive instruments. Last night we decided to apply sound to the strokes to give the illustrator another way to interact in the piece. Currently the pressure from the pen is translated into the volume and the velocity is translated into pitch. It will need some fine tuning, but I think you can get the idea from the video.

Sound Builders: Inventor of Circuit Bending Reed Ghazala

I’m really enjoying the Sound Builder series on Motherboard.tv, but this episode is brilliant. Now if I could just get the real-time version of that sped up footage! For more about Reed Ghazala checkout his bio and sounds from his instruments on anti-theory.com.

Saucer Sled Synth

Posted on May 26, 2010 by John C.S. Keston

Recently I built a Posc (Pocket Oscillator by Sonodrome) and discussed it in this entry with an audio example. Shortly afterward I built the circuit into a cardboard box and used the instrument in a number of performances and recording sessions. Now I have disassembled my beloved cardboard box and created a new instrument for an upcoming dance performance. This updated prototype is made from a plastic saucer sled, a 4″ speaker, a recycled nine volt amplifier, and the Posc circuit.

I started by drilling a grid pattern of air holes for the speaker. I then mounted the speaker behind the grid as shown. Finally I soldered the Posc circuit to the nine volt amp and the amp to the speaker. Two nine volt batteries and some duct tape completed the prototype. The night of the build I handed it to Pramila Vasudevan, the choreographer for the piece, and was amazed by the sound quality, and the response of the instrument to her movements. The final product will most likely be fabricated out of fiberglass to improve the rigidity and resonance of the disc or “shield”.

Read on to see a few more photos of the instrument.
