Look up onThe SoundForce Dual ADSR is a feature-rich, digital envelope generator made for Eurorack synthesizer systems. Designed by SoundForce, it gives you two identical, independent envelope sections (top and bottom) packed into a 20HP module. [1, 2, 3]An envelope generator shapes how a sound evolves over time by controlling parameters like volume or filter cutoff when you press a key. ADSR stands for Attack (how fast the sound rises), Decay (how fast it drops to a sustained level), Sustain (the level held while a key is pressed), and Release (how long it takes to fade out).[1]
