The Quadigy from Klavis is a quadruple, digital, seven-stage envelope generator with a few clever features. Each of the four envelopes consists of pre-delay, hold, attack, punch, decay, Sustain and release (PHAPDSR) and can be configured in detail. In addition, the curve can be inverted and looped phases can be time-aligned to the clock input. Combinations of four envelopes can be stored in 32 memory locations. Another highlight of the module is morphing via CV through the memory locations! Thanks to the graphic display, you always have an overview of the sequence times and the control of the individual function areas.
