Model 15 Complex VCO

Complex Voltage Controlled Oscillator

The name references the Buchla 258 2+5+8=15

"The Subconscious Studios Rev. 4 Model 15 VCO maintains the identical circuitry of the original discrete triangle core to assure the waveform purity and timbral characteristics which made it a legend. It features two independent fully processed (+/-) VC inputs, a 1V/Oct input, dedicated linear FM input, hard sync, and independent Sine, Triangle, Saw, PWM and a vactrol-controlled Wave Morph outputs. Operational enhancements via it's discrete SMT component design assures even greater accuracy across all functions with stability now better than .005% (less than 2 hertz drift at 1kHz over 24 hours) and single-pot frequency range from 1 to 20Khzm, at a depth of just over .5 inches below the faceplate..."
