The original Attack Decay Tape Reverse Simulator is known for producing volume and reverse swells, backward tape sounds, artificially short staccato notes, and bowed instrument effects. In 2019 the digital Attack Decay reissue was released, and now the Pico Attack Decay gives us volume envelope effects in a simplified, compact package.
