What does this do?
This is a polyphonic true analog vco. There are 4 internal vco's. You get 'one set of controls' for fast, easy polyphonic patch editing.

This product can make:
-audible sound, raw continuous.
-be 1v/octave controlled and conforms to 'popular' musical note intonation.
-can do Frequency Modulation with no harsh aliasing. This is TRUE ANALOG.
-voltages to control your other modules. -5v/+5v swing.
-polyphonic Pulse Width Modulation. 4 vco possible.
-polyphonic sync control with the 4 vco's.
-detuned unison sounds by using a mixer module to monitor.
-audible 6 wave-forms at once 'switching' patches.
-there are calibration trimmers to adjust the four fine tune knobs, and there are trimmers to 'mess up the musical 1v per octave scale'.

Label Reference:
PCV: Pitch Control Voltage , 1v/octave input
SYNC: VCO input synchronization circuit for forced HARD SYNC
PWM: Pulse Width Modulation Input, only effects the Pulse Wave.
FM: Frequency Modulation. Linear on this product.
MOD: Modulation, Exponential on this product.

LOCK: sets mode to use the small trimmer instead of big Tune Knob.
FREE: sets mode to use the Big TUNE knob and not the small trimmer.
SELECT: refers to trigger input and used to select the wave-forms. The black tactile button is a manual selector.
