Prism Delay

Eight delay lines. One instrument. Sonic nirvana.

The problem: Conventional delays don't give you the Holdsworth sound as found in the Yamaha UD-Stomp and Magicstomp.

Fig. — Prism DelaySchematic

A parallel example of the eight-line engine: stereo input is averaged to mono, while mono input is used directly. Each line contributes a panned wet signal to the stereo sum, which combines with the direct signal at the output. Connect and Group can change the line topology; the diagram is not a fixed routing preset. Tap sets the wet read position relative to loop delay, not an arbitrary number of taps per line.

Prism Delay: Three Scenes

Is this you?

  • 01You want ambience with movement in it, not a repeat with a modulation knob bolted on.
  • 02You chase the Holdsworth / UD-Stomp/Magicstomp sound and cannot source (or afford!) the discontinued hardware.
  • 03You build complex, interlocking delay patterns and need eight lines that can feed each other.

What it is

Prism Delay is an eight-line modulated multi-tap stereo delay for wide, expressive guitar and synth textures — shimmering rhythmic repeats, chorus-like ambience and expansive atmospheric washes.

The inspiration came from one of the more unusual effects units ever made: the Yamaha UD-Stomp, developed in collaboration with Allan Holdsworth. Prism Delay is not a component-level clone; it takes that multi-delay philosophy and rebuilds it for a modern plug-in workflow.

Each line has its own Time, Level, Pan, Feedback, Modulation Depth and Rate, while Connect, Group and Sync let the eight lines interact in ways a conventional multi-tap delay genearally cannot.
