OCTAVE CAT SRM I DEMO FOR MATT

video upload by Synth Tailor Electronics

"On Christmas Eve, a demo was released highlighting the wonderful, odd, and charismatic Vintage Synthesizer made by Octave Electronics, the CAT SRM (1978).

This crazy CAT SRM synthesizer packs quite a lot into it's package, and can be dialed up to make sweet, calm Cat sounds, or very weird Sci-Fi and Noise sounds.

This CAT SRM was just repaired and restored by our shop Synth Tailor Electronics, this video demo is for Matt from Sensorium Studios.

History on Octave Electronics (later Octave Plateau) CAT SRM:

In 1978 Octave upgraded the Cat to the "Series Revised Model "(aka SRM). This added several improvements, including an SSM2040 VCF, an LFO delay and a pedal input jack for offsetting the VCO1 frequency. The main improvement was the keyboard interface circuitry which included sample and hold circuits for both of the control voltages generated by the keyboard. On most duophonic synths of the era, there was only one sample and hold dedicated to the keyboard, so when playing duophonically, when the keys were released, the secondary control voltage would jump to the primary voltage, meaning that it was impossible to get duophonic notes in the envelope release phase. The Cat SRM would hold both control voltages, so a two-note chord would continue to sound as a chord through the release phase. This was an unusual feature for an analog duophonic keyboard and quite an improvement over competing designs.
