Doepfer A-141-4 Quad Polyphonic ADSR alm-busy-circuits A built-in AC jack acceptsA 141 4 is a quad voltage controlled Envelope generator and is primarily planned for polyphonic applications. The module contains four ADSR type voltage controlled envelope generators with exponential curve shapes (charge discharge curves of a capacitor). Common manual controls and CV inputs with polarizers are available for the parameters Attack (A), Decay (D), Sustain (S) and Release (R). Each of the four envelope generators has available a gate
