Patching

Grouping Segments

Complex modulations are built by grouping many segments into one modulation signal.

Inserting a jack in a GATE input marks the beginning of a group of segments. All unpatched segments at its right become part of this group.

Segment outputs

The first output of a group generates the envelope signal itself. The following outputs generate segment activity signals – ramps going from 8V to 0V whenever the corresponding segment is active.

Segment Rules

  1. The first RAMP segment ramps up to 8V, starting from whatever level the output currently stays at.
  2. The last RAMP segment ramps down to 0V.
  3. The level of a HOLD or STEP segment defines the start (end) level of the RAMP segment that follows (precedes) it. For example, in the preceding illustration, the end level of segment 3, and the start level of segment 5 are both set by the level of the HOLD segment 4.
  4. If the end level of a RAMP segment cannot be determined by rules 1, 2 or 3, this level is explicitly set by the potentiometer [A]. For example, in the preceding illustration, the end level of segments 2 and 5 are set by their potentiometer.
  5. If a LOOP is defined, the loop is played while the GATE signal is high. Once the GATE goes low, the envelope proceeds with the segment(s) that follow the loop end point. If the loop end is the last segment, there’s no escape from the loop, and the loop keeps going on forever.
  6. If the envelope contains a STEP segment, it follows its course normally until it gets trapped at the first STEP segment. It will stay at this segment until the next trigger is received. When this trigger is received, it will then proceed to the next segment… until the last segment or another STEP segment is reached. If an envelope contains a STEP segment inside a loop, there is no way of escaping this loop!


Segments

Ramp

Controls

Curve (Accelerating -> Linear -> Decelerating)
Mode Green - Ramp
Ramp Time
Ramp Time
Trigger

Description

The output glides to the target voltage with an adjustable slope, in the controlled amount of time. Start and end voltages are inferred, based on the segments coming before and after the Ramp segment. See 'Patching' for the full set of rules.


Step

Controls

Glide Time
Mode Orange - Step
Target Voltage
Target Voltage
Trigger

Description

Step segments glide to the target voltage, and remain there until a trigger is received.

When used as a single segment, Step functions as a sample and hold.



Hold

Controls

Hold Time
Mode Red - Hold
Target voltage
Target voltage
Trigger

Description

The output stays at the same voltage for an adjustable duration, then the next segment is activated. Loop a Hold segment within an envelope for traditional 'Sustain' behaviour, holding at a specific value until the gate is low.


Single-Segment

Decay Envelope

Controls

Curve (Accelerating -> Linear -> Decelerating)
Mode Green - Ramp
Ramp Time
Ramp Time
Trigger

Description

When used as a single-segment group, Ramp acts as a decay envelope with adjustable slope.


LFO

Controls

Shape (see below)
Mode Flashing Green - LFO
LFO Speed
LFO Speed
Clock (when patched)

Description

A looping single-segment Ramp acts as an LFO. The top potentiometer controls LFO shapes (see below).

When a clock source is patched into the Gate input, the LFO is tempo-synced. Stages can sync to a non-linear gate pattern as well.

Description

A single Step segment with trigger unpatched acts as a CV slew.


Sample & Hold

Mode Orange - Step

Trigger

Description

A single Step segment with trigger patched acts as a Sample and Hold. The output will glide to the target voltage on the rising edge of an input trigger, with an adjustable amount of glide time.


CV Delay

Controls

Mode Red - Hold
Voltage

Leave unpatched

Description

A single Hold segment with trigger unpatched acts as a CV delay, delaying the input voltage (and slider) by an adjustable amount of time.


Pulse Generator

Controls

Pulse Duration
Mode Red - Hold
Pulse voltage

Trigger/Gate

Description

A single Hold segment with trigger patched acts as a pulse generator, generating a pulse at specific voltage for a specific amount of time. When the segment is looped, the output will emit the specified voltage as long as the input gate is high.
