Introduction. The Z4000 is a four segment envelope generator with an additional CV processor that can be used to scale, invert, mirror, and clip the generated envelope. With its snappy envelopes, the Z4000 can generate complex CV signals for controlling any CV input in your modular. Let’s get started. To start using the Z4000, plug in a gate signal into the gate input, set ATTACK to minimum, DECAY to 50%, SUSTAIN to 50%, and RELEASE to 50%.
Segment Control Knobs Range from 50% and up From 50% and up, the segments set envelopes in the range of a second and up to minutes and infinity with the release set to maximum. Attack Curve Switch The attack curve switch (ATK) switches the attack segment slope from exponential to logarithmic. This has a subtle effect and can be heard best with envelopes having long attack segments.
Attenuverter and Deviater Explained The Attneuverter is a voltage attenuating and inverter; this means that in the 50% position, the Z4000 willl output no signal, turning the knob CW the envelope will become a positive voltage and CCW will turn it into a negative voltage. The LED will indicate those states with either an unlit, red, or yellow state, respectfully. In addition, the envelope signal passes through yet another cv processor circuit called the Deviater.
