According to the image names in this anonymous post, the cat’s name is “Tweak” (great name for a “synth cat”).

The ARP 2006 has an interesting story as well:
Another story to make you feel warm and fuzzy inside.
“around may of this year in seattle, there was a electronics recycling thing going on which i helped with… it was insane piles of electronic waste, all of which would be disassembled and sold as scrap. during this event i asked the guy in charge if i could have a old ‘music keyboard’ i found (arp 2600 + 3620keys)! (no one knew what it was but me!!!!) once home i and it was taken apart for cleaning i found it had the old ‘moog filter’ and was missing 1 speaker,only thing wrong with it! plus someone had modified it (8 extra holes plus toggle switch) sorta like 70s circuit bending i suppose.” via anonymous. Not sure about the cat connection, but there it is.

Space?Trucker also has a great desert photo. I find such images have a very inviting quality.

It’s a notable event here at CatSynth when we see catch a feline next to an Octave CAT.

There is also a wallpaper-sized version on SYNTHWIRE.
For those who may not know, the Serge Modular Synthesizers are kits that can be assembled to build large custom analog synthesizers. There are classic editions, and new editions. You can visit matrixsynth for more images and info, or visit the unofficial fan site.

ur doin it rong.
Pablo has recently discovered the qualities of analog warmth. Although he didn't get the memo where the “fat” part was supposed to be in the synth, not on it.

This weekend I decided to spend a few minutes playing with the OctaveCAT synthesizer before packing it up (part of our preparations to move). In part, I simply wanted to make sure it was working, but it is also a great instrument for improvisation.
Saw this video on matrixsynth a little back:

Basically, it's a time-lapse video of a doepfer modular being assembled. The cat shows up towards the end, and seems quite curious.
You can watch the video here. Unfortunately, it is in some sort of protected MPEG-4 format that isn't very repost/embed friendly (i.e., like YouTube videos).
