Zadar is an innovative quad envelope which can be utilized as a multi-track modulation sequencer, LFO or exciter for resonators as well. The module uses Vector models with up to 1000 segments to generate control voltages. The preset selection ranges from simple transients and classical envelope curves to complex shapes, such as those based on acoustic instruments, as well as rhythmic sequences, abstract fractals, pseudo-random functions and physical models. Each vector program can be flexibly edited and modulated.
