Boscomac has released Delight Delay, a graphically sequenced delay effect for Reaktor:
DELIGHT DELAY is a pattern-based delay controlled by a sequencer. A central display allows you to set the level and filtering rehearsals and so draw a pattern. You can set the number of repetitions (1 to 15) determine the tempo (1/4 to 1/32), adjust the stereo (mono or pingpong) and adjust the blend.
Very easy to use, this delay grooves with guitars, runs with synths, installs synchronized vibes and many other things
