Quadrature sine wave VCO / state variable filter

In stock

SKU: SCHLANGG Categories: , Brand:

Description

  • Quadrature Sine wave VCO with four phase related outputs: 0°, 90°, 180°, 270°
  • HIGH range from 10Hz to over 20kHz
  • LOW range from 0.1Hz to over 500Hz
  • Tracks volts per octave at the V/OCT input
  • FM1 is selectable linear or exponential FM via jumper on back
  • FM2 is additional exponential V/OCT jack
  • With no input GRIND section provides voltage controlled harmonic content
  • With input GRIND section compares each phase against GRIND IN signal
  • Each slider subtracts the compared signal from the input signal, creating complex waveshapes
  • When GRIND is fed into the SPIN section the outputs become a state variable filter
  • DAMPING counteracts the oscillation and allows an external signal through
  • When filtering the four phase related outputs are: LOW PASS, BAND PASS, HIGH PASS, and INVERTED BAND PASS
  • When filtering the GRIND section is a nonlinear feedback network for harsh and unpredictable timbres
  • The four phase feedback paths can be separately voltage controlled
  • The INJECT jack can be used as a second input for either audio or CV, bypassing GRIND
  • All analog OTA based design
  • 18 HP
  • Power requirements :+12V 81mA, -12V 78mA
