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.
