About Prism Delay

Prism Delay is an eight-line modulated stereo delay for guitar, synths and sound design, built for wide, animated echoes, evolving rhythmic patterns and dense spatial textures. Each of its eight delay lines can be shaped independently, then connected, grouped or synchronized to create anything from a simple stereo echo to complex multi-line delay networks. EIGHT DELAY LINES Each line gives you independent control over delay time, feedback, level, stereo pan, modulation rate and depth, filtering, phase, waveform and tap position. Use a couple of lines for a clean stereo delay, or build across all eight for layered rhythmic patterns, modulated ambience and evolving textures. CONNECT, GROUP AND SYNC Prism Delay goes beyond ordinary parallel delay taps. Connect lets one delay line feed another, allowing echoes to cascade through multiple stages. Group lets multiple lines operate as part of a shared delay structure while retaining individual tap characteristics. Sync links modulation movement between lines, with phase offsets for coordinated or shifting modulation patterns. All three can be edited directly to build your own delay structures. FIELD + LINE WORKFLOW FIELD keeps all eight delay lines visible at once, making complex patches easier to understand. Select any line to open the LINE editor for detailed control of its sound and routing. PRESETS AND MIDI Prism Delay includes a 128-slot preset system with factory presets, user preset saving and MIDI Program Change recall.
