Operat is a new-generation voltage controlled oscillator with different
modulation inputs.
 
Focused on additive synthesis by combining and feeding external signals to
it, can achieve a wide range of complex waveforms. 
The outputs include triangle, sine, sawtooth, pulse with PWM and 3 different
configurations
Four-channel mixer with linear control VCA’s sums sine, triangle, saw,  
pulse waveforms plus AM-RM circuit with crossfade and amount control.
It provides unprecedented tem-perature-compensation, with careful attention 
paid to the improvement of the triangle waveform compared to previous 
generation VCO circuits. 
Both soft, hard sync is provided.
Through-zero FM / PM can be achieved with a selector switch, with an 
amount control also modulation Symmetry.
Symmetry adjusting inverts the signal useful for LFO duties.
Audio rate signals or low-frequency signals can be chosen with a switch.

SOFT SYNC input will cause the triangle to switch from falling to rising.
The synchronization is “soft” in that it only occurs within a narrow part of the 
oscillating cycle.

Hard sync occurs at any point in the oscillating cycle. 
The HARD SYNC  has two modes of operation. 
If held high it stops the oscillator. This can be used to force the VCO to stop 
and wait for some future event. If a short pulse is used, for example, 
then hard sync will only occur on a fast rising edge (e.g., square, pulse, 
or falling saw) and will immediately force the triangle to begin rising. 

Four channel mixer with linear control VCA’s 
sums sine, triangle, saw, pulse waveforms
expecting external unipolar signals to mute them 
eventually with high events.
Each input e5V to max and 0V to close
them.

AM-RM mix circuit expects bipolar -+5V signals
AM: When the modulator will go below zero mutes
the carrier signal.

RM: When the modulator goes below zero inverts
        the signal

+5V

0V
