4-Channel CV-Controllable Function Generator with cycling, pulse burst generation and morphing LFO. Each of the four independent channels can be configured as an AD envelope, AHR envelope, cycling envelope, pulse burst generator, or morphing bipolar LFO.745
Capabilities 3
Envelope Generatorenvelope-generator
Four independent channels each configurable as AD or AHR envelope with variable response curves from logarithmic through linear to exponential.745
Function Generatorfunction-generator
Four-channel CV-controllable function generator; each channel cycles, bursts, or morphs between envelope and LFO behaviour.745
LFOlfo
Each channel can operate as a morphing bipolar LFO with five waveshapes, MORPH control, and beat-sync via TRIG input. Alternate mode provides a Low Frequency Vacillator (LFV).745

Description
Inputs (8)
CH1 TRIG
gate
—
Trigger or gate input to launch the function generator. In LFO mode, functions as a clock input for beat-synchronized LFOs.745
In AD/AHR/CYCLE modes: sets fall/release time from ~0.05ms (fully CCW) to ~50ms at noon to ~20s (fully CW). In BURST mode: sets overall burst envelope length from ~0.3ms (fully CCW) to ~20s (fully CW). In standard LFO mode: becomes MORPH knob. In alternate LFO mode: becomes VARIANCE knob.745
CH1 LINK/CV
button
—
Short press: cycles through channel link options (No Link, Trigger Link, End Of Rise Link, End Of Fall Link). Long press: enters CV Assignment mode for this channel.745
CH1 MODE/DESTINATION
button
—
Short press: cycles through modes (AD, AHR, CYCLE, BURST, LFO). Long press: toggles between STANDARD and ALTERNATE operation. In CV Assignment mode: assigns destinations and attenuversion for CV inputs.745
CH1 RISE
knob
0.05ms – 20000ms
In AD/AHR/CYCLE modes: controls rise (attack) time from ~0.05ms (fully CCW) to ~50ms at noon to ~20 seconds (fully CW). In BURST mode: sets pulse rate within burst from 0.05 Hz (fully CCW) to ~3.33 kHz (fully CW). In LFO mode: sets LFO rate from 0.05 Hz (20s) to ~3.33 kHz (0.3ms) free-running, or clock mult/div from 1/64 to 64x when clocked.745
CH1 SHAPE
knob
—
In AD/AHR/CYCLE modes: sets curve shape; noon=linear, CW=exponential, CCW=logarithmic (STANDARD); or mirrored attack/decay curves (ALTERNATE). In BURST mode: controls burst envelope and pulse waveform shape. In LFO STANDARD mode: selects base waveshape. In LFO ALTERNATE mode: slews directional changes.745
In AD/AHR/CYCLE modes: controls rise (attack) time from ~0.05ms (fully CCW) to ~50ms at noon to ~20 seconds (fully CW). In BURST mode: sets pulse rate within burst. In LFO mode: sets LFO rate or clock mult/div.745
Added CVD (Color Vision Deficiency) mode with alternative button coloring scheme. In Utility Mode, sync LEDs now flash with a trigger.745
1.3
2021-09
Added Utility Mode for manually triggering each channel and setting per-channel output voltages (5V/10V selectable, with 20% attenuation steps). Removed global 10V/5V setting from System Mode. Fixed phase/clock sync issues in LFV Mode.745
1.2.1
2021-03-09
Reduced pot dead zone. Fixed slightly longer minimum attack/decay times. Fixed LFOs not clock syncing in some cases. Fixed channel link now sends gate (not trigger) to properly support AHR hold time.745
1.2.0
2020-11-19
LFOs now phase-locked to TRIG input; linked LFOs all phase-lock to first LFO's TRIG. Snappier envelopes (near-zero attack/decay). Removed crossfade at burst mode extremes. Added 5% dead zone at pot travel ends. Various bug fixes including LFO lockup, cycle mode stuck, trigger detection improvements.745
1.1.3
2020-03-03
Fixed settings not carrying over correctly when upgrading from firmware 1.0.2 or earlier.745
1.1.2
2020-02-25
Added long-press LEVEL button in System Mode to reset module to default settings. Fixed edge case where CV assignments were not being applied.745
1.1
2020-02-06
Expanded and redesigned Burst Mode (RISE=pulse rate, FALL=burst length, SHAPE=envelope tilt and pulse waveform square-to-sine). Added Alternate modes for all five channel modes. Added System Mode for global settings. More extreme log/expo curves.745
1.0.2
2019-12-19
Modified dithering algorithm to remove quantize error noise for certain low frequency signals.745
