New Ostraka Track: Tunguska Dub

I produced this track soon after I got my DSI Tempest about five months ago. As a keyboard player one of the first things I did was hook up a MIDI controller to it. Although the Tempest is a legitimate, six-voice, polyphonic, analog synth it does not yet record chords into the internal sequencer. To get around this I simply synched the Tempest with Ableton Live and recorded the MIDI there. Obviously not an all-at-once-live-playing endeavor, but many of this machines limitations have pretty simple and effective work-arounds.

After five months of sitting on the track I finally decided to clean up the mix a little, give it the title Tunguska Dub, and preview it on SoundCloud. All of the drums, the main melody, the dub organ, and the wub bass are done on the Tempest. The SCI Pro-One is handling the main bass part, and the Super Jupiter is making the arpeggiated counter-melody.

DSI Tempest Parameter-Lock-Like Technique

I must admit that I am curious about the Elektron Analog 4 (A4), but not in the market for new gear while I am still on my honeymoon with the DSI Tempest. So, I thought to myself that as complex and sophisticated as the Tempest is there must be some way to simulate something like the A4 parameter lock (a sequencer feature that allows for real-time manipulation of synthesizer parameters on a per-step basis). So, I tried a few experiments using an unorthodox method that requires adjusting the system settings while simultaneously playing in a sequence with a MIDI keyboard. Not an ideal alternative to the workflow of the A4, but useful for me none-the-less. Distraction Surplus Syndrome was produced using this technique. The bass and sustained melodies were played on the SCI Pro-One. Let me know what you think, share your experiences using parameter-lock-like techniques, or read on for recipe details.

Post-prepared Piano Animated Sequence

I put together this animated sequence of the media from Post-prepared Piano to illustrate the relationships between the spectral analysis, the mapping with nails and twine, and the music from the piece. Thanks to Photosounder developer Michel Rouzic for suggesting that I make a video combining the sound and imagery after seeing the documentation I posted a few days ago.

Post-prepared Piano by John Keston and Piotr Szyhalski

Piotr Szyhalski and I have just finished installing a piece titled, Post-prepared Piano, in the Burnet Gallery at Le Méridien Chambers, Minneapolis. Our installation is part of a show called Interactions and features the work of select MCAD MFA students in collaboration with their mentors. Our piece consists of several components. The first part is a 14′ wide and 17″ tall inkjet print of spectral analysis from a short piano composition that I performed and recorded using my custom built, binaural head microphone (otherwise known as Vincent).

Below the print is an installation that Szyhalski constructed from tarpaper, nails, and one continuous piece of twine. This handmade mapping of the spectral analysis was then photographed and converted back into sound using Michel Rouzic’s excellent application, Photosounder. Thirdly, we installed an iPad with headphones that allows the visitors to hear the original recording, the nails and string version, and a combination of the two layered on top of one another (visit the tablet optimized webapp). The show opens today and runs through February 24, 2013 with an artist’s reception on January 31 from 6pm to 9pm. Read on for more details, photos and sounds. Continue reading
