★ Four-envelope drum voice
Four gates into G/T 1-4 · Env 1-4 each driving its own VCA or filter · kick, snare, hat and accent envelopes from one 14 HP module.
Walkthrough
  1. Press [EG]. Select Env 1 with the top-row 1 button.
  2. Set ADSR short on the first fader page: fast Attack, short Decay, zero Sustain, medium Release for a kick thump.
  3. Select Env 2 and dial a classic snare envelope (slightly longer release).
  4. Do the same for Env 3 (hat: very short) and Env 4 (accent: longer).
  5. Patch four gates from your sequencer into G/T 1-4 and the four Env outputs into four VCAs / accent inputs.
  6. Long-press [Global] so the Live LED lights — the patch is now protected from accidental editing on stage.
Signal out Env 1-4: four independent 0 to +8 V percussive envelopes, one per drum voice.
Listen for A full four-element drum voice from one module — kick, snare, hat and accent all swing off their own envelopes with no cross-talk.

★ Tempo-locked cycling pad
External clock into Clock · Env 1 and Env 2 cycling, fit-to-clock on, set to long slow shapes · they become two tempo-synced pseudo-LFOs that shape a filter and VCA of a chord.
Walkthrough
  1. Patch an external clock into Clock.
  2. Press [Cycle], select Env 1 and set Clock source to External, Divide /4, then give it a long Attack and Release on the EG page.
  3. Select Env 2 and set Clock source to External, Divide /2, then add Offset +3 so it breathes against Env 1.
  4. Patch Env 1 to your filter cutoff and Env 2 to a VCA on a held chord.
  5. Long-press [Global] to go Live. Now any tempo change in the master clock re-stretches both envelopes automatically.
  6. Play: speed up or slow the clock and both shapes follow without losing their ratio.
Signal out Env 1 and Env 2: two 0 to +8 V cycling unipolar shapes whose lengths track the external clock.
Listen for A slow breathing pad that stays locked to the track's tempo — filter and amplitude swell in a shifting polyrhythm.

Morphing preset scene
Preset 1 = snappy plucks. Preset 2 = long swells. In Live mode set a Morph Time of 8 s and either recall by hand or step with CV A — the whole envelope bank cross-fades between the two scenes.
Walkthrough
  1. In Studio mode, tune Env 1-4 to a short, percussive ADSR. Press [Preset] and save as preset 1.
  2. Edit the ADSR on all four envelopes to long swell-style shapes. Press [Preset] and save as preset 2.
  3. Press [Global] and set Morph mode to Global, Global Morph Time to 8 s.
  4. Long-press [Global] so the Live LED lights.
  5. Press [Preset] and load preset 2 — watch the envelopes crossfade over 8 s while still firing from the same gates.
  6. Optional: in Studio set Preset control to CV-A and patch a slow CV into CV A so presets step at 150 mV each.
Signal out Env 1-4: same four outputs, but their shapes evolve over the morph time from snappy to slow.
Listen for Identical trigger pattern grows from tight plucks into long airy swells — the whole envelope bank transforms rather than switching abruptly.

★ Polyphonic multi-edit
Hold [1] and tap [2], [3], [4] so all four envelopes are selected at once · tweak a single fader and all four channels track the same change — ideal for a four-voice patch where every voice must behave consistently.
Walkthrough
  1. Patch four voice gates into G/T 1-4 and the four envelope outputs into four VCAs, one per voice.
  2. Press [EG].
  3. Hold top-row [1] and tap [2], [3], [4] — all four white LEDs stay lit. Multi-edit is active.
  4. Move the Attack fader. All four envelopes take on the same absolute Attack time.
  5. Do the same for Decay, Sustain and Release. The four voices now share one consistent envelope shape.
  6. Release multi-edit by tapping a single Env button when you want to tune one voice differently.
Signal out Env 1-4: four identical-shape envelopes, one per polyphonic voice.
Listen for A four-voice patch where the whole chord breathes together — every note has the exact same attack and release.

LFO with waveshaping from an envelope
Env 3 in cycle mode with A and R set to linear at equal duration = triangle LFO · route the User knob via the CV matrix to A and R with opposite polarity · turning the knob morphs the triangle toward saw or ramp without changing the tempo.
Walkthrough
  1. Press [Cycle], select Env 3, set Clock source to Internal individual and a mid tempo.
  2. Press [EG] and set Attack and Release to equal medium times, Sustain to zero, curves to linear (noon) — you now have a triangle.
  3. Press [CV Matrix]. Hold [CV Matrix] and press the U button to pick the User knob as source.
  4. On the EG curves/timings page, use the Attack fader to set a positive CV amount from U.
  5. Repeat for Release but set a negative amount (opposite polarity).
  6. Press [CV Matrix] again to exit. Patch Env 3 to a filter cutoff.
  7. Twist the User knob: the triangle skews toward saw one way, ramp the other — the cycle length stays put.
Signal out Env 3: a 0 to +8 V cycling waveform that morphs from saw through triangle to ramp under User knob control.
Listen for A smooth filter LFO whose waveform bends from up-saw through triangle to down-saw as you turn one knob, without the rate drifting.

Clock generator and self-modulation
Env 4 cycled, A and R at zero, filling 50 percent = square clock out · route Env 1 into CV A and assign CV A → Env 4 tempo so Env 1's shape speeds up and slows down the clock — one module is now a modulated clock plus its own modulation source.
Walkthrough
  1. Press [Cycle], select Env 4, set Clock source to Internal individual, then on the EG page set Attack 0, Decay 0, Sustain max, Release 0.
  2. In the Cycle menu set Filling to 50 percent — Env 4 now outputs a square clock.
  3. Select Env 1, set Cycle = Internal individual and give it a long slow shape.
  4. Patch Env 1 output into the CV A jack (internal self-patch).
  5. Press [Cycle] again and with Env 4 selected, press [CV Matrix]. Hold [CV Matrix] + press the A button to pick CV A. On the tempo page, set a moderate positive CV amount.
  6. Press [CV Matrix] to exit. Patch Env 4 to your drum voice's clock input.
Signal out Env 4: 0 to +8 V square clock whose rate breathes with Env 1. Env 1: long slow control voltage used internally.
Listen for A tempo-modulated clock that accelerates and decelerates on its own, great for rubato drum patterns driven by one module.

Behaviors

Live vs Studio mode long press Global

Studio mode exposes every setting; Live mode hides the fragile ones and enables preset morphing plus external preset control, so a stage patch can be tweaked without breaking it.

Multi-editing hold one Env button, add others

Several envelopes can be edited together. Changes are applied as absolute values to every selected channel; the leftmost one drives the display.

Manual gate encoder press on any EG fader page

On the ADSR, timings or curves fader pages, pressing the encoder fires a manual gate on the selected envelopes — fast auditioning without an external trigger.

Cycling with fit-to-clock Cycle menu, clock source set

Each envelope can free-run, share the global internal clock, follow its own internal clock, or lock to the external Clock input. Phase times become percentages of one cycle so the overall shape stretches to tempo.

Gated cycle Cycle menu, Gated cycle On, gate into G/T

The G/T input becomes a run/stop gate. When the gate opens the envelope starts at its next offset point and cycles until the gate drops, then goes immediately to Release.

Preset morphing preset recall in Live mode

Recalling a preset smoothly morphs all continuous settings and CV matrix amounts from the current preset to the new one, over 0-120 s. Morph time is read from the target preset (or from a global setting).

Seven-stage envelopes gate or trigger into G/T, or cycle mode

Stages are pre-delay, hold, attack, punch, decay, sustain, release. Hold virtually extends the gate; punch holds at max after attack; curves for A/D/R are continuous log-lin-exp; Full Attack, Join/Restart transition, Inverted Output and per-envelope level all tweak behaviour.

156-point CV matrix CV Matrix button

Three sources (CV A, CV B, User knob CV U) can each be routed with independent amount and polarity to 13 destinations per envelope, across all 4 envelopes — up to 156 simultaneous modulations. Output Level as a destination turns each envelope into a VCA.

External preset control Global menu, Preset control set to Trigger or CV-A

CV A can step through a user-defined range of presets by trigger, or select them by voltage (150 mV per preset from 0 V). Combines with morphing for hands-free scene changes.

Global Quad Control Timing Global menu, QCT page

One fader per envelope, acting either as global time stretch, per-envelope tempo, global-clock tempo, or clock mult/divide depending on each section's cycle mode — a quick per-channel performance page.
