Weekend Cat Blogging #297: Construction again

The on-again off-again construction at CatSynth HQ is finally on again for real. That meant Luna had to go back to boarding for a couple of days, but I brought her back home the weekend. Here we see her inspecting the state of the work:

Hopefully it will be done early next week. The whole process has been a bit stressful for both of us. I hope letting Luna enjoy some time at home over the weekend is indeed better for her, and I’m not adding to her stress or exposing her to much fallout from the construction work. It’s certainly far less than what we went through in late 2008, so hopefully it’s OK.


Weekend Cat Blogging #297 is being hosted by Oliver and Noli at The Accidental English Teacher. This is their first time hosting!

The Carnival of the Cats will be hosted by Nikita at Meowsing of an Opinionated Pussycat. This is definitely not his first time hosting.

And the Friday Ark is at the modulator, back from hiatus.

Fun with Highways: Cairo Edition

Paul Cowan, Cameron Soren, Amy Yao, Jancar Jones Gallery

A couple of weeks ago I stopped by Jancar Jones Gallery to see the current exhibition featuring works by Paul Cowan, Cameron Soren and Amy Yao. One the things I like about visiting is the gallery itself, a small but inviting room tucked away on a rather idiosyncratic block of Mission Street in SOMA. Despite being such a small space, the exhibitions are always sparse and calming. (You can see previous reviews of exhibits at Jancar Jones via this link.)

Perhaps the pieces that most caught my interest were Paul Cowan’s two paintings featuring musical notes, both with the label Untitled, 2010. Each features a single quarter note on five-line staff without a clef. Assuming an implicit treble clef (which is admittedly a big assumption), the notes would be A and G, respectively. The “A” is on a very sparse canvas with red lines, similar to something I might have had to draw out myself during early years of studying music. The “G”, by contrast is filled in with vibrant color fields, though once again red is the most prominent color.

The other piece that caught my attention was Amy Yao’s Dealing Don’t Cry, which featured three small bits of newspaper fastened to a horizontal wooden dowel. The bits of text on two of the paper bits feature the text “Dealing” and “Don’t Cry” – I am always interested in the use of text, especially when the context is missing. My understanding in this work is the title is derived from the material, rather than text being found to fit the title.

Rounding out the exhibition was Cameron Soren’s untitled video installation depicting the gallery on the opening on January 7, 6-9PM.

This is the final weekend for the exhibition – it closes on February 12 – so stop by if you happen to be nearby.

Preparing for Regents’ Lecturer presentation, Part 1

I have been busily preparing this weekend for the first of my UC Berkeley Regents’ Lecturer presentations:

Open Sound World (OSW) is a scalable, extensible programming environment that allows musicians, sound designers and researchers to process sound in response to expressive real-time control. This talk will provide an overview of OSW, past development and future directions, and then focus on the parallel processing architecture. Early in the development of OSW in late 1999 and early 2000, we made a conscious decision to support parallel processing as affordable multiprocessor systems were coming on the market. We implemented a simple scalable dynamic system in which workers take on tasks called “activation expressions” on a first-come first serve basis, which facilities for ordering and prioritization to deal with real-time constraints and synchronicity of audio streams. In this presentation, we will review a simple musical example and demonstrate performance benefits and limitations of scaling to small multi-core systems. The talk will conclude with a discussion of how current research directions in parallel computing can be applied to this system to solve past challenges and scale to much larger systems.

You can find out more details, including location for those in the Bay Area who may be interested in attending, at the official announcement site.


Much of the time for a presentation is spent making PowerPoint slides:

With slides out of the way, I can now turn to the more fun part, the short demos. This gives me an opportunity to work with TouchOSC for the iPad as a method for controlling OSW patches. We will see how that turns out later.

Carnival of the Cats #360

We at CatSynth would like to welcome everyone to the 360th Carnival of the Cats, one of the longest running weekly roundups featuring cats from around the blogosphere.  You can find out more, including how to participate, at the Carnival of the Cats website.  If you would like to participate today, you can use the handy submission form, or leave a comment below.

First, we open with a fast-forward Luna’s WCB photo from yesterday.  She is after all the host for this week.

And while she keeps busy with her napping, we proceed to the carnival proper.  First up, we have Maddie relaxing in her box of paper.

It turns out that “Maddie in the box with paper” scans perfectly to “Lucy in the Sky with Diamonds”.  Trippy! The cats at StrangeRanger also have some new portraits posted today.

Next up, we have a few submissions from our friends Nikita and Elvira.  First, we see them enjoying a lazy Friday afternoon.  But they have also been industrious, registering for Blog Paws 2011.  This a leap of faith, as they and their dad (like many) had a rough 2010.  But there is also bright news, as Elvira prepares to celebrate her first birthday.

Happy birthday in advance!

We at CatSynth marked Groundhog Day this past Wednesday.  But Hakuna remains unimpressed. “Groundhog Day? Screw that. When’s Caturday?”

You have to appreciate that surly expression.

Rather than being surly, Samantha and Clementine seem fascinated by the snow that has been falling in Texas.

Based on all the commentary about the Super Bowl in Texas today, I am guessing this is not supposed to happen.

Catsparella presents this post featuring cats with heart-shaped fur markings:

This should probably come with a cuteness warning of some sort.

That concludes the carnival for now.  We will continue to update with any submissions we receive through the end of Sunday.  Thanks to all who participated.

Ivy Room Hootelatkenanny, December 2010

Today we look back at the Ivy Room Hootelatkenanny, the December edition of the Ivy Room Hootenany improvised music series. The Ivy Room in Albany, CA, has in fact turned into a great venue for new music, with many performances even beyond this long-running series. The combination of music, mixed drinks and quirky decor seem to come together.

Despite the play on words in the title, there was nothing Hannukah-related about the performances that evening.

The first set featured a quartet I put together with Bill Wolter on guitar, Dave “Djembe” Coen on percussion and JP O’Keefe on drumset. Gear-wise, I kept things pretty minimal, with just the Dave Smith Evolver and the iPad running Curtis and the Korg iMS-20 apps.

I started out the set with my usual metallic patch on the Evolver, and quickly added granular sweeping with Curtis. Slowly the percussion came in, with soft rolls on the cymbals and djembe. As Bill Wolter with soft chromatic harmonies on guitar, I switched to a different Evolver patch and to the iMS-20 with some analog-like arpeggios. These set up a rhythmic foundation which the drums matched with a strong 16-note rhythm – the tempo and pulse were reminiscent of disco but texture and individual rhythmic phrases were more complex – something akin to 1970s fusion. The iMS-20 served as a de facto bass with heavily filtered patches set against the guitar improvisation – at various times I opted for a softer tone like an electric bass, others a highly synthetic sound like a “techno bass.” Harmonically and melodically, we danced around blurs, pentatonic, chromatic and tri-tone patterns against the ever changing but steady pulse rhythm of the two percussionists. At one point, Bill started playing the strings below the bridge and I used this sound effect opportunity to return to Curtis. We kept the pulse going for a bit, then cut out for a quiet moment. Then the rhythm gradually re-emerged, a bit more tribal and accented off beat, and with more inharmonic timbres on synth and guitar. Then we returned the jam feel with guitar, bass and drums, and continued in one of these patterns or another for the remainder of the set, at one point switching to a 6/8 rhythm with a more humorous sounding synth line. I have to admit, this was one of the most fun I have played in a while, both idiomatic and experimental at the same time, both completely free-form and rhythmically structured. I will have to get this quartet back together again sometime soon!

We were followed by the duo of Kenneth and Kattt Atchley. Their music also combined experimental electronic elements with a strong idiomatic style, in their case something reminiscent of late-night electronic music at dance clubs or lounges. They did several distinct pieces during their set. The had a slow steady rhythm with soft electric-piano chords set against analog or analog-like electronic sounds, relative high pitched with pitch LFO. The chords and rhythm continue in a very moody, almost R&B fashion while the high pitched electronic sounds ride above more rapidly. Then all at once it stops, replaced by a very distant-sounding synth pad, and the voices and poetry returned amidst the sparser texture. The music moved back and forth seemelessly between these two overall textures. Kenneth and later Kattt at various moments intone “I wouldn’t change a thing” and descriptive phrases about “East Bay nights” and “Pacific Fog cooling the air”. The texture eventually gave way to harsher electrical noises and pulsating sounds that still have a harmony of their own – and one can still hear minor chords in the background. When the chords and rhythm return to the forreground, there are a bit more fragmented than before.

The next piece was entitled Over Ice. It started with very liquidy and crystalline sounds, with words and melody in a descending minor scale. There was something vaguely religious or spiritual sounding about this pattern, almost like a chant. A sparse rhythm emerges, and the high crystalline sounds remain in the background. It eventually because very abstract, with electronic hits and noises sounding at first in a random pattern that gradually becomes more rhythmic. After a monologue section, the original melodic pattern returned, but with a more rhythmic foundation.

The final set featured Dean Santomieri with Michael Zelner on reeds, and Suki O’Kane “massaging the skins”, i.e. on percussion. It consisted of improvisation around a series of poems featuring “spine words” and “spine phrases” based on Jonathan Franzen’s best-seller Freedom. Things opened with resonating cymbols and Santomieri’s introductions, followed by the initial poem based on the spine word “Franzen.” The music consisted of short clarinet and percussion phrases filling in the spaces in between Santomieri’s words, with some more extended instrumental lines. The overall texture was very sparse with individual notes, but also some jazzy phrases and some extended wind techniques set against a diversity of percussive sounds. Among the spine phrases used were “left right rhetoric”, “Lolita” and perhaps the most memorable “Franzen, Franzen, Franzen”. Indeed, the author’s name was frequently used in many playful contexts, such as “Franzomancy reveals a function, the zen idolatry…”. Section with more complex and richly tonal words followed by noisier and squeakier instrumentals. During one of the poems, Zelner switched to extended-technique flute, which was set against small metallic and wooden percussion from O’Kane. He returned to clarinet this time employing multiphonics for the final poem, which again used the spine “Franzen, Franzen, Franzen”.

Weekend Cat Blogging #296

It looks like it’s going to be another beautiful morning here.  Luna maintains her routine on sunny mornings of bedding down on a dining room chair.  And while I am busy working, she is dreaming:


The Carnival of the Cats will be hosted here at CatSynth tomorrow! If you would like to participate, please fill out the handy submission form.

Like many, we have been hungrily following the events in Egypt (if by some chance, you are not following this, you should be) – and excited to see hopeful changes for the people there. While the focus is of course on the major political changes and peoples’ safety, I did look into stories about animals in the land that once worshipped cats as gods. Through this article, we did read about Egyptian Mau Rescue, and browsed the Facebook page for the Egyptian Society for Mercy to Animals. Ultimately, these visits ended up being a narrative about people and the challenges they face caring for animals amidst major upheaval.
