Cycle

The Cycle function makes the envelope self-cycle (LFO mode). When this button is lit,

Cycle

the envelope will keep running without needing any external triggers. Pressing the

Cycle button will toggle the cycle state on/off.

The Cycle jack toggles the cycling state. By default, when a gate is applied to this jack,

the Cycle button will toggle state (on→off and off→on). When the gate is released,

cycling will revert to its previous state. In System Mode, this jack can be changed to

Cycle

toggle the cycling state each time it receives a trigger. So if Cycle is on, a trigger will

turn it off, and a subsequent trigger will turn it on again.

Depending on whether the module is in Sync or Async mode, the envelope will start

playing from a different point (starting phase) when the Cycle button is pushed. See

Sync and Async Modes section.

Trigger

The Trigger jack initiates an envelope when a trigger is received. By default, the

envelope starts immediately and the module is put into Async mode. Holding the trigger

high will have no effect. In System Mode, this jack can be configured as a Quantized

Trigger

jack, so that receiving a trigger will cause an envelope to output on the next ping clock.

When used this way, the module will be put into Sync mode when it receives a trigger.

Holding the Trigger jack high will cause the envelope to cycle until released.

The jack can also be configured as an Async Gate jack. This is the same as the default

behavior (Async Trigger), but the envelope will sustain if the gate is held high past the

end of the rise phase. When the gate is released, the fall stage will start.

Async modes allow you to re-trigger an envelope that's already running, while the

Quantized mode does not. See Sync and Async Modes section and System Mode

sections.

Shape

The Shape knob and jack control both the skew (or ratio of rise to fall times) and the

selection of waveshapes (logarithmic, linear, exponential). While there is a continuous

spectrum of waveshapes, the range can be divided into three zones.

The first zone is from fully counter-clockwise to around 9:30. Turning the knob

clockwise, the envelope starts as a ramp-up exponential shape and slowly turns to a

Shape

linear ramp-up shape.

The transition from the first zone to the second zone goes from a ramp-up linear shape

to a balanced exponential shape (equal rise and fall times) at about 10:00.

The second zone begins with the balanced expo shape. It then transitions to a balanced

linear shape at the knob's center position, and then to a balanced log shape at about

Shape CV

2:00.

The transition to the third zone turns the balanced log shape into a ramp-down linear

shape at about 2:30

The third zone mirrors the first zone, going from ramp-down linear to ramp-down

exponential.

The CV jack ranges from -5V to +5V and offsets the knob's position.

Scale

The Scale knob is an attenuverter for the main envelope output, ENV OUT. If the scale

knob is right of center, the output voltage will increase when the envelope is in the rise

Scale

phase, and decrease when the envelope is falling (non-inverted). This is normally how

envelopes are used. If the Scale knob is left of center, the envelope will be inverted and

the output voltage will decrease as the envelope rises, and increase as it falls.

As you turn Scale towards center, the amplitude will decrease, moving the peaks

towards zero. At center, there will be no output (technically, it produces a steady DC

voltage which is set by the Shift feature).

Offset

The Offset knob shifts the envelope on the ENV OUT jack up and down by adding DC

offset. The offset is applied before Scale is applied. For a positive-only envelope,

Offset would typically be set at maximum, and Scale should be right of center. For a bi-

Offset

polar envelope, Offset should be set to center. For a negative-only envelope (non-

inverted), Offset should be set to minimum.
