Attack Decay Tape Reverse Simulator

The pedal reshapes the volume of what you play rather than recording anything. Each note starts a fade-in at an adjustable speed and a fade-out at another. Slow settings give backward-tape swells, while fast settings cut notes into short staccato bursts. A sensitivity control sets how hard a note must be played to trigger a new envelope.

In mono mode one envelope runs at a time and restarts with each new note. Poly mode gives every note its own envelope, so chords and overlapping notes swell separately. The Harmonix section is a fuzz with its own gain, tone and volume controls.

The Send and Return jacks place the envelope on whatever signal arrives at the loop, so other pedals or a second instrument can be shaped by it. An expression pedal or control-voltage input reaches every knob, and three presets store settings. Bypass is buffered rather than true bypass.
