getting ready for tomorrow's performance, part 1

Well, it's time to stop fooling around with pictures and get back to using Open Sound World for what is was intendend, making sound. In preparation for my performance tomorrow at the Skronkathon, I have selected a couple of patches that have worked well for me in the past. They are quite robust, and provide a variety of musical gestures and timbres that complement the sound generated by Ron Lettuce on his PVC wind instrument.

First there is my sinusoidal timbre space based on bifurcation diagrams from classic chaotic functions, controlled using my Wacom graphics tablet. If that sounds really complicated and weird, just accept for the moment that it sounds really cool, and that I will post a more in-depth article about it along with sound clips in the near future. The second patch uses a WX7 wind controller to control a set of resonance models and the excitations used to drive them – essentially, a metallic chamber that one plays like a wind instrument (clarinet, saxophone, etc.). Both of these programs were used in my performances with ELSA Productions last year.

Before today, I had been a bit worried about using my Dell laptop for the performance, as it had a tendency to start running the fan at full blast and slowing to a crawl, especially when running a CPU-intensive program like OSW or Emulator X2. Things would get even worse running a program like Poser or Bryce that is both CPU and graphics intensive. I installed the fan control software and cleaned out the internal fans and heat sink as described in this article and others, and while this has helped, it hasn't cured the problem, particularly with respect to graphics. I fear the root cause of the problem is simply that the laptop, which is nearly three years old, is simply nearing retirement.

In any case, I am also the planning to use the Evolver and the feedback+filter technique I described in a previous article. I generally have both a hardware synth and computer running simultaneously during live performances, so that if the computer and software crash I still have something to play. This has paid off on numerous occasions.

And that's pretty much it. It doesn't sound like a lot, a couple of very focused synthesis techniques, but by listening and playing them like traditional instruments, I expect to get a ful musical performance – I often advise such a “simple” approach to live electronic performance when asked by other musicians.

So that's it for now. I'm off to San Francisco for my one “rehearsal,” taking a leisurely trip up Highway 1 to Half Moon Bay and then cutting over to get to the city. More later.

DSI Evolver legal again in Kansas public schools

After the recent electoral defeats of Creationists on the Kansas school board, students are now free again to use the Evolver synthesizer from Dave Smith Instruments. Was the Evolver an unintended victim of the continuing assault on the theory of evolution and scientific reason, or part of an orchestrated effort to eliminate all electronic music in Kansas except for the DX7 electric piano patch used by wedding and bar-mitzvah bands?

Speaking of music spawned by the devil, I have been experimenting a lot lately with the use of feedback as the primary sound source for the filters instead of the starndard oscillators. The instability combined with the filters and multiple conversions between analog and digital in the signal path make for some very interesting results. I have posted an example here for your listening pleasure. Be forwarned, there are a lot of harsh high frequencies in this example, though the MP3 compression does help soften them a bit. Enjoy!

More Cats and Synthesizers

It looks like some others out there had the same idea. Check out this post at Create Digital Music featuring photos of animals with synthesizers. While the author is an admitted dog person, there are several cute cat pics, including this one from the Matrixsynth blog:

The synthesizer in this photo is the legendary and all-too-appropriate Octave CAT.

Also at Matrixsynth is Arak and Legion. Arak is handsome black cat, like Luna but with yellow eyes, more like a Bombay. Matrix also has an adorable shot of his black cat JD with a Sequential Circuits Multitrak. Check it out, it looks like he's actually reviewing patch specs.


Sadly, it sounds like Arak has passed away and JD isn't doing very well. My heart goes out to Matrix, Legion and their kitties. Our animal companions truly share our lives, even our odd hobbies.
