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.

Reminder About the GMS Generative Track Competition

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

I have received a few notices of intent to participate in the GMS Generative Track Competition, but no entries so far. The deadline is still May 31, 2010, but I may extend it if necessary. Please drop me a line if you’re intending to submit something, or need more time. Here’s the original entry that includes the details about the competition.

Korg Monotron First Impressions

Posted on May 10, 2010 by John C.S. Keston

Lately, as you might have noticed, I’m attracted to synthesizers that don’t necessarily use keyboards for input. The Korg Monotron is a $60.00 battery operated true analog synthesizer with a ribbon controller and five knobs to control pitch, LFO rate / intensity, and VCF cutoff / peak. The Monotron will be available in the US this July. For more details checkout this article on Synthtopia.com.

Read on for more Korg Monotron videos. The next one is especially good.

Frequency Modulated Drone Generator

Posted on May 9, 2010 by John C.S. Keston

I’m currently working on a sound design project for a client who is looking for a way to generate specific sorts of sounds using easy to understand controls. I started by creating a frequency modulated drone generator. The tool has a mixer with six preset pitches plus noise. I also included amplitude modulation, with sliders to control the amount, LFO, and a frequency multiplier to allow for FM synthesis effects. Here’s an audio example that illustrates the range of sounds possible with this set of fairly simple and intuitive controls.
