Time CV Jack and Rise/Fall CV Knobs

The Time CV jack modulates the Rise and Fall times of the envelope. The

jack feeds two knobs: Rise CV, and Fall CV. Each of these knobs is an

attenuverter (short for "attenuating inverter") and controls how much the

control voltage on the Time CV jack will affect either the rise or the fall time.

Turning an attenuverter knob to the right of center means that a positive

voltage on the Time CV jack will lengthen the rise/fall time and a negative

voltage will shorten the rise/fall time.

Turning a knob to the left of center gives the opposite effect, meaning that a

positive voltage on the Time CV jack will shorten the the rise/fall time, while a

negative voltage will lengthen these durations.

The farther you turn the knob from center in either direction, the more effect

incoming CV will have. When the knob is centered, the signal on the Time

CV jack will have no effect on the rise or fall time.

Next to each knob is a light which indicates the strength and polarity of the

modulation. The light will turn blue when the rise or fall time is being

lengthened by CV, and red when the time is being shortened. The brighter the

light, the more of an effect the CV is having. When the light is off, the Time

CV jack has no effect on the envelope time.

When nothing is plugged into the Time CV jack, the knobs act as fine-tuning

controls for the Rise and Fall times.

Env Out Jacks, OR Jack, and LEDs

The Env Out A and B jacks output the envelopes for each channel. DC offset

and vertical scale of each channel's envelope are determined by the positions

of the Level and Offset knobs. The OR jack compares both Env Out signals

and outputs the highest voltage value between the two at any given moment.

The lights near each jack indicate the amplitude and polarity of each

envelope. When the envelope is somewhere between 0V and 10V, its

respective light will shine blue. When the envelope is somewhere between

-10V and 0V the light will shine red. The brightness of each light indicates the

amplitude of the outgoing signal, so when the light is off, this means the

signal is outputting at or around 0v.

Level and Offset Knobs

The Level knob attenuates and inverts (attenuverts) the envelope output on

each Env Out jack. When Offset is centered, turning Level fully clockwise

will output a positive envelope, with a maximum peak of about 10V. Turning

the knob counter-clockwise inverts the envelope. When Level is fully counter-

clockwise, the output will peak at about -10V.

Turning the Offset knobs clockwise will add a positive offset between 0V and

10V to the envelope, while turning the knobs counter-clockwise will add a

negative offset between 0V and -10V. See Using Level and Offset on page 18

for more details.

Note that neither the Level pots nor the Offset pots affect the envelope going

to the internal VCAs. For example, if the Env Out jack is patched to a

modulation input on an external module while audio is running through the

VCA, Level and Offset can be used to control the amount of modulation

without changing the audio level.

EOR and EOF Output Jack

The EOR (End of Rise) jack is specific to Channel A. It outputs a gate that

goes high when the rise stage ends and the fall stage begins. It remains high

as long as the envelope is falling, and goes low when the envelope

completes. When the envelope is not running, the EOR jack will stay low. The

EOR light will shine whenever the output is high.
