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
