11:11 on 11/11/11

At 11:11 on this day 11/11/11, I snapped screenshots of both the iPad and iPhone featuring Luna.

Of course, the symmetry and homogeneity of the date and time is quite attractive, and unique (at least within a given century). The number 111111 is also interesting when you decompose it into primes:

111111 = 11 * 13 * 3 * 37 * 7

I find the prime factorization quite poetic.

We can also factor the date and time together (11:11:11 on 11/11/11):

111111111111 = 11 * 13 * 3 * 37 * 7 * 101 * 9901

Note quite as poetic as the previous example, but still interesting. In particular, 9901 is interesting as the greatest prime factor for any repeating series of 12 numbers. Other related properties can be seen at the site Prime Curios.

Weekend Cat Blogging: Luna and Apple

The influence of Apple and Steve Jobs extends deep into this site and into our lives at CatSynth HQ. For today’s Weekend Cat Blogging, we look at a few of the many photos of Luna with Apple computers and devices:

This last photo is one of our many taken with the Hipstamatic app on the iPhone.  Indeed, most of the photos, even those not taken with an iPhone, are processed on a MacBook or Mac Pro.  Nearly all of the writing is done on a MacBook, and occasionally on an iPad.  The technology of Apple has become ubiquitous, even down to blogs featuring cats.


Weekend Cat Blogging #331, is hosted by pam at Sidewalk Shoes, where Smudge says Happy Fall to everyone.

Carnival of the Cats will be up tomorrow at Meowsings of an Opinionated Pussycat.

Weekend Cat Blogging: Luna discovers iPad game for cats

I recently downloaded an iPad game for cats by Hiccup for Luna to try out. For a cat that spends a lot of time surrounded by technology, including the iPad, she is quite reluctant to touch it, so I wasn’t quite sure how she would react.

The game features a little mouse that resembles a cat toy scurrying around the screen. When the cat (or human) hits the mouse, it emits a little squeak and the player receives points; and the process repeats. That’s it – very simple. I started it up for Luna, and she immediately went to tracking the mouse intently, her little head shifting back and forth in deliberate motions. Tentatively, after a while, she started to paw at it, and eventually managed to pounce on the mouse. She seemed to be quite enjoying it, though she was still a little nervous and often backed away from the device after a pounce.

Here a brief excerpt of her first day of playing:

This is really just a little diversion for both of us to enjoy together, Luna playing with a virtual toy that draws her attention, and my taking delight in watching her do so. But this is clearly a demonstration of user engagement in the app space, for both cats and humans. Sometimes simplicity wins out.

I set up the game again in the office/studio while writing this article, and managed to get a brief iPhone video of Luna’s play. As one can see, she has gotten a bit more confident, even aggressive with it.

This does not seem to be a good game to play a small cluttered space.

Weekend Cat Blogging and Photo Hunt: Korg MS-20 Patch

The theme for this week’s combined Weekend Cat Blogging and Photo Hunt is Patch. We at CatSynth have an alternative take on the theme, as Luna poses with a Korg MS-20 patch on the iPad:

As a bonus, the app’s simulated interface features patch cords. They’re a little challenging to manipulate on the screen, but the make for nice visuals.


Appropriately for an iPad-centric post, Weekend Cat Blogging #320 is hosted by Meowza at his blog iMeowza.

Photo Hunt 275 is hosted by tnchick. This week’s theme is Patch.

Outsound Music Summit: Touch the Gear and Non-idiomatic composition

The Outsound Music Summit began this Sunday with the annual Touch the Gear Expo. Visitors have a chance to see and try out the equipment used by musicians and sound artists. We had a a diverse group of participants this year, and this short video gives a good overview of some of the sound and visuals that one would have encountered:

We had a decently sized turnout for the event, and the evening went by quickly. While not at my own station, I did my best to see others work, but did not get to everyone. For those who followed my live tweets from the event, the remainder of article might seem redundant, but I do provide more detail.

I brought a small rig that reflects my recent solo work, with an iPad as both a synthesizer and controller for software on the laptop, a monome, the Wicks Looper and a Korg Mini-Kaoss Pad.

The iPad was primarily running TouchOSC, controlling a version of my piece Charmer:Firmament running in Open Sound World on the laptop, as well as a few popular instruments like the Smule Magic Fiddle and Bebot. The monome was controlling sample loops, and the Wicks Looper was feeding into the Kaoss Pad.

Next me, Matt Davignon presented a turntable and effects pedals that was quite popular with visitors. There is still something compelling about a tactile and intuitive interface such as a turntable that compels people to want to play it. In contrast, the monome in particularly seemed to intimidate people.

There were many non-electronic offerings as well, including the quartz cantabile by Todd Larew. Who needs electronics when you have fire as your primarily technology!

Bob Marsh wandered the hall in a suit covered in plastic water bottles, some containing mechanical sound generating elements, and was quite a presence throughout the evening.

He also brought several other articles of sonic clothing for people to try on and play.

Tim Thompson brought his space palette, a large wall-sized controller in which one controls sound and visuals by moving in the various spaces in the panel.

I had seen him perform with the space palette before, but this my first opportunity to try it out myself.

Another original instrument, the Ernestophone, featured one main string and several sympathetic strings, and a very rich sonic palette of overtones.

Phogmasheen presented an instrument made from pick heads and cake pans.

One strikes the metal elements with mallets or sticks, and then pickups process the output electronically.

This is not the first time I have seen a classic 1950’s HP oscillator at Touch the Gear, but it’s the first time I have seen one paired with a Peerless transistor radio, for a very retro noise experience.

Noise rigs are a common theme, particularly chains of effects pedals and mixers that operate solely on the noise inherent in electronic circuits but then amplify and shape it through non-linear processes of the effects change into rich and chaotic sound palettes. One example is this colorful rig from CJ Borosque. I was able to get subtle an expressive control of the sound by focusing on only a couple of knobs.

Other participants included Tom Nunn presenting one of his sonic inventions, Rick Walker demonstrating high virtuosic use of live-looping hardware and Laurie Amat getting rather humorous results from the sound of the crowd in the hall processed through a classic green Line6 delay pedal.


The panel discussion on Monday night, entitled “Elements of non-idiomatic compositional strategies” was quite a contrast to Touch the Gear Night. Four composers, Kanoko Nishi, Andrew Raffo Dewar, Krystyna Bobrowski, and Gino Robair engaged in a discussion moderated by Polly Moller about their music, influences and views on composition in front of an intimate audience with plentiful wine, cheese and dark chocolate.

One of the interesting questions was whether each of the composers began their ideas with sound, or a focus on sound. Not surprisingly, the answer was no – although sound was the medium of creativity, the source ideas can come from anywhere. In speaking about his piece for the Friday concert at the summit, he described how the work was influenced very directly by paintings by the Argentine artist Eduardo Serón. Gino Robair similar painted a very visual and conceptual influence for his suite based on the engravings of Jose Guadalupe Posada of late19th -and early 20th-century life in Mexico, and the skeletons and skulls in particular. Kanoko Nishi referred “music completely devoid of symbols”; and Krystyna Bobrowski described her work with her created instruments as a “sonic bloom of resonance”, perhaps my favorite phrase of the evening.

Other topics discussed included composing for instruments or sounds versus composing for particular musicians, i.e., “instead of preparing the piano, prepare the pianist” (as I pianist, I am not sure how I feel about being prepared), and questions about the rewards of composing experimental music – because it was accepted by panelists and audience alike that their are neither financial nor sexual riches to be gained by this pursuit. Perhaps the response that rang most true to me was that composing music is an obsessive-compulsive activity that some of us just have to do whether we like it or not.

For those who not familiar with the terms, think of idiomatic music as music that falls into recognizable patterns and genres that one can readily identify, so non-idiomatic music is music that attempts to defy such categorization. However, I often find the dichotomy not particularly useful. I sympathize with the composers’ desire to two work that transcends past categorization, and I often strive to do the same thing – but we can’t help but be influenced by the music and sounds around us, and shouldn’t necessarily fear the appearance of these influences in music that we call “new”. It was also interesting how much all four panelists distanced themselves from mathematics, even while acknowledging the deep and longstanding interconnection with music.

All for composers will have work on the Friday night concert at the Outsound Music Summit. Click here for more details.

CatSynth 5th Anniversary!

Today we mark the 5th Anniversary of CatSynth!

I started this site on July 19, 2006 as a novelty when a friend and former colleague at E-MU systems suggested that I “should make a website about cats and synths.”

Every anniversary we feature the photo of Luna from the inaugural post.

I still have that Novation keyboard, though it does not get used as often of late. Luna of course still is very territorial about that beanbag chair. Times have changed a bit, here is an iconic photo of Luna from this past year, this time with an iPad app (in this case, the Smule Magic Piano):

Another quirky way we like to celebrate is with statistics. First the basics:

1559 posts.
0.85 posts per day.
8784 comments.
5.63 comments per post.
476 posts featuring cats and synthesizers.
195 reviews (and gig reports).
381,735 visitors.

Even after five years, people from around the world continue to send us pictures of cats and music gear. These days most of those come via our Facebook, which together with twitter has become a major way people engage with this site.

From Google Analytics (which we finally got working properly over the past year), here is an overview of where our visitors come from around the world.

By far and away most of our visitors are from the United States, followed by the United Kingdom, Canada, India, Australia, France and Germany. I’m gratified to see so many visitors from India, though I’m curious why we never receive any comments from there…

It’s also interesting to look at cities.

Not surprisingly, the top cities are San Francisco and New York. In Google, it’s SF followed by NYC, while in Facebook, New York is the top city.

Our most popular posts judged by number of visitors are the annual endangered wild cats on earth day.  Over the past year, our most commented posts were:

Wordless Wednesday: Herman (Groundhog Day) 35
Wordless Wednesday: Doll and Metal Beams 28
Wordless Wednesday: 6506 (Baker Beach) 27
Wordless Wednesday: Matzoh Man 27
Happy Birthday Luna! 25
Wordless Wednesday: 7643 (New York, Late Autumn) 25
Wordless Wednesday:  Wet Paint 25
Wordless Wednesday: Mosaic with Saxophones 24
Wordless Wednesday: Summer Solstice 24
Wordless Wednesday:  Harrison Street Hipstomatic 23

Our top commenters the past year:

Thanks to all our friends (in time zones earlier than U.S. Pacific Daylight Time) who already sent in comments for the anniversary, and to the Cat Blogosphere for their anniversary shout-out!

And while we will continue to keep doing what we do, it has been more of a challenge over this past year to keep up with posts, especially the longer-form reviews. There is a trade between doing music and art, and writing about people doing music and art. But I still love doing everything here, and will find a way…

Weekend Cat Blogging and Photo Hunt: Busy

There is rarely a moment that we at CatSynth aren’t busy, thus it is an appropriate theme for this week’s combined Weekend Cat Blogging and Photo Hunt. Even going into the extended holiday weekend.

Luna poses once again with the iPad, but the app on display isn’t as exciting as the synthesizers and music controllers we usually show. It’s Toodledo, the cloud-based todo-list service that I use on iPhone/iPad and the web in a valiant attempt to keep ahead of the extreme busy-ness of the past two years. Not very exciting, but we do our best to make it at least look pretty in photos.

For those who obsessively try to do such things, the task being shown on these photos (strategically distorted via the Hipstamatic) is a daily reminder to brush Luna. There is also a weekly task for Weekend Cat Blogging. Many of the tasks on the list are about getting in touch with friends and professional contacts. I do need to catch up on those! On that note, we have been a bit remiss in visiting our WCB friends. We will try to do so this time.


Weekend Cat Blogging #317 is hosted by our friends Kashim, Othello and Salome. Even though they live in Vienna they honor us with a Fourth of July theme.

Carnival of the Cats will be up this Monday (rather than the usual Sunday) in honor of the Fourth of July as well, hosted by Nikita and Elvira at Meowsings of an Opinionated Pussycat.

Photo Hunt #272 is hosted by tnchick. This week’s theme is BUSY.

And the Friday Ark is at the modulator.

Regents Lecturer Concert, CNMAT (March 2011)

Today we look back on my solo concert at the Center for New Music Technologies (CNMAT) at U.C. Berkeley back in early March. It was part of my U.C. Regents Lecturer appointment this year, which also included technical talks and guest lectures for classes.

This is one of the more elaborate concerts I have done. Not only did I have an entire program to fill on my own, but I specifically wanted to showcase various technologies related to my past research at CNMAT and some of their current work, such as advanced multi-channel speaker systems. I spent a fair amount of time onsite earlier in the week to do some programming, and arrived early on the day of the show to get things set up. Here is the iPad with CNMAT’s dodecahedron speaker – each face of the dodecahedron is a separate speaker driven by its own audio channel.

Here is the Wicks Looper (which I had recently acquired) along with the dotara, an Indian string instrument often used in folk music.

I organized the concert such that the first half was more focused on showcasing music technologies, and the second half on more theatrical live performance. This does not imply that there wasn’t strong musicality in the first half or a lack of technological sophistication in the second, but rather which theme was central to the particular pieces.

After a very generous introduction by David Wessel, I launched into one of my standard improvisational pieces. Each one is different, but I do incorporate a set of elements that get reused. This one began with the Count Basie “Big Band Remote” recording and made use of various looping and resampling techniques with the Indian and Chinese instruments (controlled by monome), the Dave Smith Instruments Evolver, and various iPad apps.

The concert included the premier of a new piece that was specifically composed for CNMAT’s impressive loudspeaker resources, the dodecahedron as well as the 8-channel surround system. In the main surround speakers, I created complex “clouds” of partials in an additive synthesizer that could be panned between different speakers for a rich immersive sound. I had short percussive sounds emitted from various speakers on the dodecahedron. I though the effect was quite strong, with the point sounds very localized and spatially separated from the more ambient sounds. In the video, it is hard to get the full effect, but here it is nonetheless:

Realignments – Regents Lecturer Concert, CNMAT from CatSynth on Vimeo.

The piece was implemented in Open Sound World – the new version that primarily uses Python scripts (or any OSC-enabled scripting language) instead of the old graphical user interface. I used TouchOSC on the iPad for real-time control.

I then moved from rather complex experimental technology to a simple and very self-contained instrument, the Wicks Looper, in this improvised piece. It had a very different sound from the software-based pieces in this part of the concert, and I liked the contrast.

The first half of the concert also featured two pieces from my CD Aquatic: Neptune Prelude to Xi and Charmer:Firmament. The original live versions of these pieces used a Wacom graphics tablet controlling OSW patches. I reimplemented them to use TouchOSC on the iPad.

The second half of the concert opened with a duo of myself and Polly Moller on concert and bass flutes. We used one of my graphical score sets – here we went on order from one to the next and interpreted each symbol.

The cat one was particular fun, as Polly emulated the sound of a cat purring. It was a great piece, but unfortunately I do not have a video of this one to share. So we will have to perform it again sometime.

I performed the piece 月伸1 featuring the video of Luna. Each of the previous performances, at the Quickening Moon concert and Omega Sound Fix last year, used different electronic instruments. This time I performed the musical accompaniment exclusively on acoustic grand piano. In some ways, I think it is the strongest of the three performances, with more emotion and musicality. The humor came through as well, though a bit more subtle than in the original Quickening Moon performance.

The one unfortunate part of the evening came in the final piece. I had originally done Spin Cycle / Control Freak at a series of exchange concerts between CNMAT and CCRMA at Stanford in 2000. I redid the programming for this performance to use the latest version of OSW and TouchOSC on the iPad as the control surface. However, at this point in the evening I could not get the iPad and the MacBook to lock onto a single network together. The iPad could not find the MacBook’s private wireless network, even after multiple reboots of both devices. In my mind, this is actually the biggest problem with using an iPad as a control surface – it requires wireless networking, which seems to be very shaky at times on Apple hardware. It would be nice if they allowed one to use a wired connection via the USB cable. I suppose I should be grateful that this problem did not occur until the final piece, but was still a bit of an embarrassment and gives me pause about using iPad/TouchOSC until I know how to make it more reliable.

On balance, it was a great evening of music even with the misfire at the end. I was quite happy with the audience turnout and the warm reception and feedback afterwards. It was a chance to look back on solo work from the past ten years, and look forward to new musical and technological adventures in the future.
