DPLR is a delay module with two interactive delay lines, each with 750mS of delay time.

One input is split to two delays which share overall delay time (DELAY) and regeneration (REGEN). Side B has control over its delay offset (SPREAD) from side A.

Delay, Spread and Regen are all voltage controllable. Regen at max will echo indefinitely, and can create interesting noise swashes.

The pushbutton at the top taps through seven different crosstalk configurations (Regen isolated through ping-pong). Push and hold to change through four different Regen Filter settings from very bright to dark.
