Preparing for tomorrow's today's performance, part 2

Things were looking pretty dire yesterday afternoon, with major audio problems on both the PC and Mac. Without going into details, I was getting intermittent pops, clicks and stutters on the PC, and the Mac was simply outputting something wrong. Eventually, I was able to get the mac working with clean audio, so that became the computer for today's performance, together with an E-MU 0202 | USB and an Xboard.

Basically, the mac is running Open Sound World, more specifically, the latest version that works with my new Python interface. Without the pesky graphical interface, the system is rock solid and a lot more efficient to program. It's more akin to SuperCollider or the practice of “live coding”, if you are familiar with either of those. So with this setup, I was able to get things up and running for today very quickly. And it is rock solid, though I don't want to jinx the actual performance too much by describing all the things that didn't happen.

The “instrument” for today allows two live recordings to be played back at various rates, controlled by the MIDI keyboard and knobs. I will be playing several of my Indian instruments to feed the recordings, in particular the ektar (single-string instrument) and the gopichand (also single string, with a bendable neck for pitch modulation).

Of course, the ketzela wants to get in the act again, too:

One last-minute change was dealing with my Xboard killing itself (something stupid on my part, really). Fortunately, I also have the Novation keyboard as a backup, and although the keyboard itself isn't as good, the controllers are a better fit.

The setup is also extremely compact. This is all I have to carry:

Well, actually, this and the folding table I usually bring. Still, it will be very light and relatively easy to set up (especially as the mac boots very quickly).

One day I caught Mingus stomping on various keys of the keyboard I had left on the floor. Funny thing, Mingus was named after Charles Mingus, the jazz bass player. I didn't bother to look what patch he had punched in on the synthesizer, whether it was set to “bass” or “fiddle”. He does also have a Beethovenesque look on this pose, doesn't he? Who knows…

Doesn't Mingus look a bit like Luna?

Thoughts on last night's performance

In this article I review my performance last night at the plug:dos headphone festival in San Francisco.

First, the venue itself. 5lowershop is in a warehouse near the junction of highways 280 and 101 in San Francisco. It’s at the edge of the Bernal Heights neighborhood.


The venue and its surroundings have that seedy edge-of-the-city feel that I probably wouldn’t want to live in but nonetheless often find intriguing and romantic. It’s just another part of the quintessentially “modern” world.

The interior matches the exterior, a jumble of areas within the warehouse, including the main performance area. The space is quite porous with the outside, and I noticed several cats wander though, including the grey fellow and a small black-and-white kitten. They were presumably feral cats attracted by the warmth, activity and possibility of food. Feral cats are an inevitable part of urban environments, but it’s still heartbreaking to see them this way. I was also concerned for them because of the dogs that were present, fortunately the dogs seemed to be pets and quite mellow.

The atmosphere of people crowded in a warehouse listening to headphones was quite unusual to say the least. Some of the performances were quite interesting, including a serinate for voice and hammer-dulcimer, and of course several acts mixing guitar, analog synthesizers and turntable. The analog synths didn’t strike me as a good fit for headphone performance, and thus avoided them myself (as described in my article on the preparation), but they did a good job of keeping the sound within a reasonable range.

Despite the best efforts of the organizers, whom I liked and thought did a good job overall, things tended to run rather late, and I ended up going on 9:40PM, two hours after my scheduled performance. But I think it went well musically, pretty much meeting my expectations for mixing ambient and rhythmic/punctuated material while keeping things mellow for the headphones. I did bounce around and repeat elements more than I expected, but such is the nature of improvisation, reacting as things unfold.

The equipment (Dell Laptop, Emulator X, E-MU 1616m, E-MU Xboard 25) performed flawlessly. I did make a direct recording on the laptop, and will be posting that shortly. I am also planning to make that the first release in my planned podcast series.

UPDATE: you can now listen to the audio from this performance. Enjoy!

Preparing for tomorrow's performance

My upcoming performance at the the plug.dos headphone festival provides some special challenges. Because the audience, both at the venue and online, will be using headphones, I need make sure my sounds and processes are headphone-safe, i.e., low volume with no clipping, glitching or large volume-spikes. More positively, I can take advantage of a uniform stereo listening environment with deliberate pan and positioning effects.

The need for steady volume and stability rules out the use of feedback and high-resonance filtering that I use in a lot of my recent music. Thus, the Evolver is out. Many of my Open Sound World patches are probably not approrpriate, though stable-volume patches are certainly doable.

I am focusing on Emulator X controlled with a MIDI keyboard (E-MU Xboard25). Thus, my preparations have focused on selecting existing sounds from the E-MU sound library that meet my technical and aesthetic requirements, and creating some new sounds. One preset that I spent a lot of time building is a modification of my additive synthesizer for Emulator X, consisting of eight independently controllable sinewaves. In addition to MIDI control of amplitude and frequency, I use a function generator to add amplitude modulations do the sinewave components of the timbre. Additionally, each “note” played has an independent pan position, spreading the sound across in the stereo field. I have also modified some existing sounds to include stable amplitude-modulation effects. The end result is a highly-controllable pallete of sounds from which I plan to make an ambient but punctuated sound scape, with a few rhythmic elements for good measure.

Logistically, this will be a very simple performance to travel and set up, just my laptop, the E-MU 1616m sound module, and the keyboard. I am looking forward to a relaxed, simple and enjoyable experience.

I'm not posting any advance examples, so you'll have to listen online to the show to hear what I'm describing. Hopefully I will be able to post a recording after the fact.
