Preparing for March 4 Concert, Part 2

On Tuesday, I went to the Center for New Music and Audio Technologies (CNMAT) in order to continue preparing for the Regent’s Lecture concert on March 4.  I brought most of the setup with me, at least the electronic gear:

Several pieces are going to feature the iPad (yes, the old pre-March 2 version) running TouchOSC controlling Open Sound World on the Macbook.  I worked on several new control configurations after trying out some of the sound elements I will be working with.  Of course, I have the monome as well, mostly to control sample-looping sections of various pieces.

One of the main reasons for spending time on site is to work directly with the sound system, which features an 8-channel surround speaker configuration.  Below are five of the eight speakers.


One of the new pieces is designed specifically for this space – and to also utilize a 12-channel dodecahedron speaker developed at CNMAT.  I will also be adapting older pieces and performance elements for the space, including a multichannel version of  Charmer:Firmament.  In addition to the multichannel, I made changes to the iPad control based on the experience from last Saturday’s performance at Rooz Cafe in Oakland.  It now is far more expressive and closer to the original.

I also broke out the newly acquired Wicks Looper on the sound system.  It sounded great!

The performance information (yet again) is below.


Friday, March 4, 8PM
Center For New Music and Audio Technologies (CNMAT)
1750 Arch St., Berkeley, CA

CNMAT and the UC Berkeley Regents’ Lecturer program present and evening of music by Amar Chaudhary.

The concert will feature a variety of new and existing pieces based on Amar’s deep experience and dual identity in technology and the arts. He draws upon diverse sources as jazz standards, Indian music, film scores and his past research work, notably the Open Sound World environment for real-time music applications. The program includes performances with instruments on laptop, iPhone and iPad, acoustic grand piano, do-it-yourself analog electronics and Indian and Chinese folk instruments. He will also premier a new piece that utilizes CNMAT’s unique sound spatialization resources.

The concert will include a guest appearance by my friend and frequent collaborator Polly Moller. We will be doing a duo with Polly on flutes and myself on Smule Ocarina and other wind-inspired software instruments – I call it “Real Flutes Versus Fake Flutes.”

The Regents’ Lecturer series features several research and technical talks in addition to this concert. Visit http://www.cnmat.berkeley.edu for more information.

Some preparation for March 4 concert

A late evening preparing for the upcoming Regents’ Lecture concert, with an assist from Luna:

Here Luna poses with TouchOSC on the iPad, which is becoming one of the main control surfaces I will be using to control Open Sound World.  Last night I was building the synthesis infrastructure for the new piece, a combination of drum sampling and spatialized additive synthesis – at least four separate additive synthesis models that are algorithmically generated based on input from the iPad.  Against this will be electronic drum sounds and an Afro-Cuban rhythm detail.  I really won’t know the exact shape of this piece until I work with CNMAT’s speaker array.

I also learned from the Saturday’s performance in Oakland that I will need to refine the control on TouchOSC for the new implementation of my piece Charmer:Firmament.  It was very well received, with descriptions like “beautiful” and “meditative”, but it was difficult to control compared to the Wacom graphics tablet.  I will try a different mix of controls on the iPad to see if it works better.

Preparing for tonight’s performance

I will be performing tonight in Oakland at Rooz Cafe (1918 Park Blvd, Oakland, CA) at 7PM tonight. Details below:

-Animated, explosive inside/outside music

I have been busily preparing today with a small setup, similar to one I had planned for January 17:

Once again, I will have the monome controlling the MacBook, primarily for live sampling and looping today. I will be using the dotara, an Indian folk string instrument, as one of the live sample sources. I will also bring a bell and the prayer bowl as live sources. The iPad will be running Curtis, which gets more an more advanced with each upgrade and is becoming a true musical instrument. I will also be using TouchOSC to control Open Sound World, including a brand new implementation of my piece Charmer:Firmament for iPad, replacing the retired Wacom graphics tablet. This is a dry run for the big concert next Friday (March 4), so we’ll see out it goes.

I had been hoping a new contact mic would arrive today – I am considering that for March 4 as well – but of course FedEx showed up just while I was out at an important art-related meeting, so I missed it and they are the one courier that won’t leave things. So I will be using an ordinary mic once again for the live sampling/looping – maybe it’s for the best.

Update: Just as I finished posting this article, a package arrived.  Not the contact microphone, but it was an exciting new toy, the Wicks Looper.

You see previous CatSynth pics and videos with this and related devices via this link (the cat in most of these is also named Luna). I have been considering getting one these for a while, and the current run of performances provided the impetus.  Although I have not yet played it, I am seriously tempted to try it out for tonight’s set.  After all, what’s the worst that could happen?

Zimoun and Jim Haynes at Swissnex

In mid-January, I had the opportunity to see a performance by Swiss artist and instrument-maker Zimoun and local artist Jim Haynes at Swissnex here in San Francisco.

Swissnex is tucked away on quiet block in a “neutral zone” between the FInancial District, Chinatown and North Beach (an area I enjoy passing through on some of my long walks). The space is very minimal and stark white, with bits of the structural architecture and industrial quality of the building present. Within this space, a large array of music-making machinery was set up. One one side was Zimoun’s very minimal instrumentation, and on the other the chaotic array of gear and elements that would make up Haynes’ performance.

Zimoun’s instrument was incredibly simple, a series of cardboard boxes on top of which were mounted ping-pong balls on motorized arms. The boxes served as resonant chambers for the excitation of the ping-ping balls.

The performance unfolded as simply as the instrument itself. First, one of the five units began to vibrate, producing a low rumbling sound. Gradually the other ball+motor+box elements entered the mix, producing an odd harmony of machine noises. Out of this combination, I heard a higher-pitched metallic sound. I am not sure if this came directly from the machinery of the instrument, or was an acoustic artifact from the interaction of the different sounds. That is one of the interesting things about having such a minimal concept behind a piece, it allows one to focus on the output and explore minute details that would often be lost in a more complex performance. The piece continued as continuous sound, without much in the way of change or development, for about twenty minutes. The combination of the sound and visual environment allowed for a few minutes of peaceful detachment and I was able to experience it purely as signal and image processing without social context.

Jim Haynes’ performance was a sharp contrast to Zimoun, both aurally and visually. His table was covered with a diverse array of audio devices and lab equipment.

At first, I took the metal column and rings to be a custom-made theremin of sorts before realizing that it was the rings and tower familiar from countless science classes.

After an initial burst of loud noise and feedback (which reassuringly let us all know that “yes, this thing is on”), the sound unfolded as an exploration of traditional elements, notably fire, air and earth. He opened with fire, specifically from the flame of a lit candle. He latter added sand, which poured from a bottle he placed on the metallic rings so that the sand could gradually fall out onto a contact microphone. While Zimoun’s performance invited detachment, Haynes’ required close attention. Many of the sounds that emerged seem closely related to the elemental sources: from the fire a series of crackling sounds and wind sounds from the excited air, and from the sand a sea of granular noises that could at times seem like liquid. But there were other sounds as well, the sound of ambient radio static, something akin to vinyl noise, a high-pitched shaking sound, and metallic rattling. Whether these were directly from the fire and sand or from the BOSS Dr. Sample and associated effects boxes is unclear.

This performance was in many ways a preview for Zimoun’s exhibition at the Gray Area Foundation for the Arts (GAFFTA) which opened a few days later. That exhibition is still ongoing and will close on on February 22nd. Follow the link for more details.

CatSynth pic: Diego and Befaco Slicer Prototype

From comun y corriente, via matrixsynth:

Googlish translation from matrixsynth:

The other Diego had domestic problems that will prevent you bring your Spanish guitar, so you will be forced to play with this wild animal.

And another picture from amstrad on flickr, featuring Kiska:

Finally, an update from c+c via the comments on matrixsynth:

ust a brief explanation of what was going on here… This was published a couple of days before our first Corrientazo, a concert featuring many musicians using compact synthesizers and DIY stuff. So we were announcing that Diego, from Befaco, was going to play with a prototype of their new Slicer / 8 step sequencer, to be released later this month (more info soon!).

Then I heard news from Amstrad that he was no longer going to play spanish guitar + MFB 522 in the concert, because the cat ate the guitar! So he brought his DIY modular, from the Befaco workshops, instead; and played it via MIDI from his iPhone!”

I would be curious to hear the iPhone + Befaco performance…
