Tiptop Audio Z4000 VC-EG Cheat Sheet

The Z4000 is a four-stage envelope generator (Attack, Decay, Sustain, Release) with unique CV processing features (Attenuverter/Deviater) for shaping, scaling, inverting, mirroring, or offsetting the envelope.


🛠 Panel Controls Summary

Name Type Function Range
A (Attack) Knob Sets attack time; voltage controllable 0ms to minutes (via knob & CV)
D (Decay) Knob Sets decay time; voltage controllable 0ms to minutes (via knob & CV)
S (Sustain) Knob Sets sustain level; voltage controllable 0V (min) to ~8V (max, via knob & CV)
R (Release) Knob Sets release time; voltage controllable 0ms to ∞ (fully CW) (via knob & CV)
Attack Curve Switch (ATK) Toggle Selects attack curve slope (exponential/logarithmic) N/A
Attenuverter Knob Scales and inverts envelope output; 12h = 0V, CW = full pos, CCW = full neg ± envelope out
Deviater Knob Offsets envelope output voltage (+ or - static voltage) ± static V
Deviater CV Amt Knob Level of external signal mapped by Deviater VC input N/A

🔌 Jacks Reference (Inputs & Outputs)

Jack Label Type Function Voltage Range
GATE In Gate/trigger input to start envelope +2V min (typical)
RTRG (Retrigger) In Pulse retriggers envelope during held gate +2V min (typical)
A, D, S, R In Voltage control for Attack, Decay, Sustain, Release 0–5V = 0–100% of parameter; summed w/ knob
DEVIATER VC In Modulates Deviater offset 0–5V for full range
OUT Out Main envelope output (processed by Attenuverter and Deviater) ±8V maximum (scaled/inverted/offset)

🚦 Usage Quick Start

  1. Basic Envelope
  2. Plug gate into GATE
  3. Set envelope shape:
  4. Set Attenuverter to full CW (full pos)
  5. Set Deviater to center (0 offset)
  6. Patch OUT to desired CV input (VCA, filter, etc.)

  7. Sculpt Envelope

  8. Adjust A/D/S/R for shape and timing.
  9. First 50%: fine tuning, ultra-fast percussive/transient control
  10. Above 50%: extends segment times up to minutes or infinite Sustain
  11. Switch ATK (Attack Curve) for subtle slope changes.

  12. Advanced Shaping

  13. Attenuverter:
  14. Deviater

  15. Voltage Control

  16. Patch CV sources (sequencer, LFO, other envelopes) into A/D/S/R or Deviater VC as desired
  17. 0–5V = full range for segment control (CV is summed with knob)

  18. Retrigger

  19. Send pulses to RTRG (while GATE is held) to restart Attack for accents, modulation, or rhythmic variations
