New Podcast: Remix of Ninjam sessions June 15/17, UCSC DANM exhibition.

Well, it's another Sunday, and another podcast for the CatSynth Channel.

Tonight's podcast features some live internet improvisation using NINJAM, a system that allows people to share live audio in real time and thus jam together over the internet. To overcome network latency that has stymied most systems for online collaboration, NINJAM actually adds delay so that everyone's audio conforms to a particular meter and tempo, i.e., everyone's down beats are in sync though they may be a measure or two off from one another. This leads to either simple “groove” jams on one or two chords and a steady beat (think of the 70s jazz classic Chameleon), or freeform improvisation.

The particular sessions used in this remix were from June 15 and 17 featuring several performers live at the Digital Media Factory in Santa Cruz California as part of the MFA Exhibition for the Digital Art and New Media (DANM) program at UC Santa Cruz. Though I am not a student, one of my best friends is, and so I had the opportunity to perform in several of the jams with local musicians as well as others over the internet.

Out of several hours of material, I made a 30-minute “remix” of several of the jams. The feel ranges from free-form to driving funk/jazz rhythms to a relaxed fusion/lounge feel (this happened when most of the musicians turned out to be keyboard players) and more.

All recorded mixes from the NINJAM AutoSong Archive, which are the sources for this track, are released under the Attribution, Noncommercial, Share Alike Creative Commons License v2.5..

Collaborators on the various jams include synthany, mvollrath, dbkick, tbfx, Funkify, leftyf, Oubien_ke, ekinox, hotdog, and chazz. (Sorry if I missed anyone).

Synthany is Synthia Payne and friends at the DANM exhibition, where I played as well. For my parts, I used E-MU Emulator X2 on my PC laptop, doing keyboard/piano, rhythms (using TwistaLoop), and even some bass when it was needed.

As always, comments are welcome. I'm not sure my brief discription really did justice to the topic or this particular example of online music collaboration, so feel free to ask more about it, or research the topic for yourself. In the meantime, enjoy.

Wine country

Sitting outside this fine summer evening with a glass of wine reminds me that I haven't written about my trip to the wine country from Memorial Day weekend.

The “wine country” to which I am referring is the Napa Valley, north of San Francisco. (This is not to be confused with the Santa Barbara wine country in Sideways). The heart of the wine country is corridor along highway 29 north of the town of Napa:

I'm not sure why I thought that weekend would be a good time to go. Highway 29 was a parking lot the entire way from its start in Vallejo through at least the town of St. Helena. It is a pretty undersized highway for such a heavy tourist destination, but one can understand why they may not want to expand it too much. It is, however, an expressway and freeway in area in and around the town of Napa (within the city limits, it was a full-on freeway). The reason this photo taken just south of Napa is so clear is because I wasn't moving.

It seems like they should consider upgrading the remainder to a freeway at least through Yountville, which is considered the start of the main wine country. At this point, 29 becomes a two-lane road amongst vinyards, eventually meeting up with highway 128 around St. Helena, which pretty much lives entirely off the wine and wine-tourism industry. 29 and 128 continue north through some of the most upscale vinyards before splitting at the resort town of Calistoga.

One of the main wineries I visited was in fact just a bit south of Calistoga. Clos Pegase was of particular interest not because of the wine per se (though the wine was quite good), but the owner's extensive art collection, mostly 20th century works. Among them are this monumental mobile by George Rickey:

George Rickey's work was familiar, having seen at least one other example at the New Orleans Museum of Art scupture garden during my trip last year.

This linear-geometric piece by Tony Smith really works with the rows of grape vines:

I often try to find just the perfect perspective when confronted with such strong lines. You can see another example (one of my favorite among my “art photos”) from the Getty Center in Los Angeles, one of several on my photography page (which I really need to update one of these days).

Another interesting geomtric metal piece, this one by Joel Shapiro:

Of course, the collection is not just abstract work. There were several figurative pieces as well, including this sculpture by Henry Moore, which appeared to have gotten the “John Ashcroft Treatment”:

Of course, they had wine, too. Of particular note was the cabernet franc. Most American winedrinkers will be familiar with cabernet sauvignon, which are often my favorite wines. “Cab franc” is another grape that is often used in blends, but Clos Pegase's solo version was a great discovery.

The town of Calistoga is perhapsa better known for water than for wine. Calistoga gives its name to brand of mineral water popular here at CatSynth (though they were not offering tours despite the “come visit us sometime” suggestion on the label). It is also known for its many hot springs and spas. But beer? Well, it did try a very distinctive beer from the Russian River (in neighboring Sonoma County), with a rather sweet taste. Ironically, this was at wine bar that I stopped into while spending time until a spa appointment. This particular bar called out to me with its metalic modernist trendy urban look and vibe, compared to the general rustic charm of Calistoga – there is a definite “look” that most resort towns in northern California have that looks like a hybrid of Gold Rush and New Age. Nonetheless, I think I picked the right alternative for myself, and also enjoyed this little pasta-and-goat-cheese nibble.

I definitely recommend a wine-country trip for anyone in the extended Bay Area, though maybe not on the busiest travel weekend of the year. Maybe not a good trip for those who dislike wine, art and spa treatments. We at CatSynth refer to such people as “strange and weird.”

Weekend Cat Blogging #107: Peek-a-boo and Stray Cats

WCB 107 is being hosted this weekend at ScamperDude.com, where Scampy is playing both Rock Star and Super Hero.

Luna has some antics of her own, ratcheting things up in our regular hide-and-seek games:

I noticed that that Luna's eyes appear yellow instead of green in this an many other photos taken in the more earth-tone bedroom. Regular fans of Luna know that she has unusually green eyes for a black short-hair cat.

Her antics and affections have been quite welcome of late, it seems like a bit of a melancholy week despite the beginning of summer, and the brightness and warmth in abundance.

On a recent series of morning walks I saw several cats, most of whom were probably strays, like this rather thin character with a striking coat and photogenic appearance:

He/she was one of several cats taking up residence in the large vacant trying separating a large residential neighborhood (my neighborhood, actually), from a Safeway parking lot and strip mall. I hope they get enough to eat.

A few weeks ago, I stopped at the semi-annual rummage sale for one of the main local groups that helps stray cats in our community, Project Purr.

Picked up a few books while I was there, some summer reading. I was mildly tempted by a full set of “Left Behind” paperbacks, but thought better of it.

Also check out Friday Ark #144 (Saturday is the new Friday), and of course Carnival of the Cats.

Originally from gerald:

My cat loves the Lissajous this thing generates

So what is a “Lissajous”? it is actually short for Lissajous curves or Lissajous figures, a class of 2D (and 3D) curves describing complex harmonic functions, or more simply multi-dimensional sine curves. The following equations describe a general Lissajous curve on an x-y coordinate plane:

x = A sin(at + φ)
y = B sin(bt)

Most of the time, one leaves out the A and B, which case all the curves fall on a convenient unit square.

The most commonly described Lissajous curves set the phase term φ to π/2, i.e., a standard cosine function, and have a and b at integer ratios, like 1:2, 6:5, etc. You can think of these as natural harmonics, like in musical sounds. You can see a few of the graphs below, first for a=1 and b=2:

Here are 3:2 (a:b), and 9:8, respectively:

As you can see, the higher the ratio, the more complex and dense the figure. If you add all the figures up together, you should be able to fill the entire unit square.

There are all sorts of interesting special cases. For example, if you set a and b equal, you will get a circle. If you additionally set the φ to zero, you will get a straight line. Finally, you can mess with different values of φ, like 0.3 in the first drawing below, or set a and b to non-integer values, to get all sorts of interesting variations:

It is interesting to think about these sorts of functions by relating them both visually and aurally (i.e., synthesizing the corresponding waveforms), but we will leave that as an exercise for interested readers, perhaps returning to the topic in a future article.

The CatSynth Eighty-three

It seems like everyone these days has a “top 100 list”, indeed we are listed on a few of them. Well, we at CatSynth like to be different, so we're introducing the “CatSynth 83.” All sites related to cats, synthesizers, electronic music, or any of the other topics frequently discussed on this site like highways, mathematics, software, etc., can apply. We will list to top 83 participating sites. So come and join the only top-sites list based on a neglected prime number.

Worthless Kitty Backfill: Salman Rushdie knighthood protests

Here is a small sample of calm and well-thought-out reactions to the recent knighting of British author Salman Rushdie:

The Senate of Pakistan expresses its strong condemnation on blatant disregard for the sensitivity of the Muslims of the World shown by the British Government by awarding a Knighthood to Salman Rushdie, who committed blasphemy against a pillar of Islam, the persona of Holy Prophet,” said the resolution moved by the leader of the [Pakistani parliament] Wasim Sajjad and supported by all opposition groups. [Times of India].

We will give 10 million rupees (165,000 dollars) to anyone who beheads Rushdie,” Islamabad traders' association leader Ajmal Baluch told around 200 people in one of the Pakistani capital's main bazaars.[AFP]

Not to mention this heart-warming photograph:

C'mon, “Biggest Evil of the World”? Did you guys forget about the whole invasion and occupation of Iraq, a (mostly) Muslim country, where lots of people are actually dying? And you wonder why you guys have such a bad rep…

The ironies of course are that The Satanic Verses didn't seem all that blasphemous when I read it years ago – it was mostly about a snooty anglophile from Bombay, with occasional interludes – and that Salman Rushdie has written many other works. One of my favorites was Haroun and the Sea of Stories, a childrens book. We did a children's theatre play based on the book while I was at Yale, for which I composed several original works – everyone's favorite was the disco soundtrack for the chase scene. It was a fun exercise in how to make a children's tale something dry and off-beat while keeping it suitable for a young audience.

I think this lolcat is particularly apropos:

Charles Mingus Cat Toilet Training Program

Speaking of Mingus and cats, I might as well post this surprising article from the legendary Jazz bassist himself. Here is the Charles Mingus Cat Toilet Training Program. It ends with the following:

It took me about three or four weeks to toilet train my cat, Nightlife. Most of the time is spent moving the box very gradually to the bathroom. Do it very slowly and don't confuse him. And, remember, once the box is on the toilet, leave it a week or even two. The main thing to remember is not to rush or confuse him.

Good luck. Charles Mingus

Yes, I wasn't sure this was for real, either, but it does appear on an official site that includes information about the Mingus Bands as well as the life and activities of his wife Sue Mingus following his death in 1979.

As one other bookmark on del.icio.us states, “I respect Mingus even more now.”

CatSynth Pic: Hey Diddle Diddle Goes Techno

From Stephan71 at flickr:

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?
