Tiptop Audio Z4000 Voltage Controlled Envelope Generator
The Z4000 is a snappy voltage-controlled analog envelope generator with a built-in CV processor for scaling, inverting, and voltage-controlled deviating of the envelope shape. The Z4000 generates an envelope made of the four classic segments: Attack, Decay, Sustain, and Release, in which each segment can be manually set using knobs or dynamically set under voltage control.
Control knobs for the Attack, Decay, and Release segments are scaled. The first of the knobs’ rotation is dedicated to high-resolution adjustment in the millisecond range; this allows for a fine adjustments that reduce clicks and pops to a minimum with the lowest possible delay and loss in snappiness. Conversely, the rotation of the knobs from 50% to 100% provide envelopes that can last anywhere from several minutes to infinity.
The output levels are fully adjustable with signals that can reach up to 10V in either polarity and can be mirrored into the opposite polarity or clipped using the voltage-controlled deviater scaler. A bi-color LED indicates intermediate values in both polarities and their crossfade state.
The Attack slope switch allows selection of a logarithmic or exponential curve for the Attack segment; this subtle effect helps further the fine adjustment of the Attack segment slope. A shoot button is provided to let you fire the enevlope manually. The Z4000 also provides a retrigger input allowing you to create legato notes when using a classic keyboard interface.
Going down to nuts and bolts, the Z4000’s smoothness and snappiness is made possible by a four-segment active-charge discrete circuit which is an extended version of circuits found in classic two-segment rise/fall transient generators.
