CatSynth pic: Adventures in Electronic Music with Little Cat

Little cat with final synth

From Charles Petzold’s highly recommended article Adventures in Electronic Music. You can read it in its entirety here.

Turning 90Β° to the left, you can see the windows in my apartment overlooking Broadway, flanked by steel shelving containing my LP collection and a pair of Polk speakers. My bed is to the left. (Yes, this is a studio apartment.) The edge of my piano can be seen at the far left. Little Cat is on the floor.

The synthesizer in its final form was capable of generating 80 simultaneous sine waves, combined in pairs for simple FM synthesis of 40 tones at a sampling rate of 31,250 Hz. For the multiplication of the sine curve values by the amplitude, I used a massive 64-pin TRY MPY16HJ chip, which could perform a 16-bit by 16-bit multiplication in 50 nanoseconds. (How fast can the microprocessor in your desktop computer perform a 16-by-16-bit integer multiplication?) This dedicated multiplier chip cost $241.

Interesting to think about how computer and DSP technology has changed.

Via matrixsynth. This one is a true blast from the past, posted there only a week after CatSynth was founded πŸ™‚

This one in via Michael. “Attached photo: Rico the cat playing a solo lead line while accompanying self on Rhodes. He hasn’t yet got the hang of the (unfinished) modular, but my other cat has opposable thumbs and is a fast learner. Putney and Minimoog on loan from Reed.”

CatSynth Pic: Kimball Collins with Roland V-Synth XT

Kimball Collins

From an eBay auction, via matrixsynth.

“The ultimate FSU rack sampler/synth. Includes vocal processor & D-50 modes. Comes with PCMCIA-to-CompactFlash adapter and 512MB CF card loaded with waveforms for synthesis exploration. Useful as an external effects processor, too. Clean condition, smoke free home, minimal rack rash on included ears.”

“The cat’s name is Kimball Collins (after the DJ).”

While not much interest per se in this specific synth, I have been a bit curious about the Roland D50/D550, mostly because I like the partials. If you have opinions about either the Roland V-Synth XT or the D50/550, please let us know in the comments πŸ™‚
