Doepfer A-143-2 Quad ADSR

The Doepfer A-143-2 Quad ADSR is a powerful and compact Eurorack module offering four independent ADSR envelope generators. Each ADSR features Attack, Decay, Sustain, and Release stages, adjustable via dedicated controls, giving you detailed control over modulation dynamics.

The envelopes are triggered by gate or trigger signals and are ideal for modulating filters, VCAs, oscillators, and other modules with precise timing and expressive control. Its compact design with four channels in one module provides an efficient solution for more complex patch setups without occupying excessive rack space.
