The MSP-126 occupies a unique space in the signal processing world. With twelve independently controlled delay taps — six per channel — it can do things that neither a conventional delay line nor a reverberator can. Transparent mono-to-stereo conversion with perfect mono compatibility. Early reflection patterns that simulate acoustic spaces without the long decay tail. Delay-based panning that holds up off-center. Musically tuned comb filters. Stereo echo patterns that bounce between speakers. Eight distinct processing modes, each with 256 combinations of delay and gain settings — and an addictive sound you'll want to put on everything.

This plugin faithfully emulates the original's hardware PROM-driven architecture. Only about 70 units were ever made, so finding one today is almost impossible, but now you can have this rare piece of kit in your DAW 100% bit accurate to the original.

Eight Modes of Processing

MSP11 — Stereo Processing

Converts mono to stereo with flat frequency response across left, right, and mono sum. The most transparent mode — ideal for general-purpose stereo enhancement.

CSP — Comb Filter Stereo

Complementary comb filters create dramatic stereo coloring while maintaining perfect mono compatibility. Like a static flanger with two mirror-image outputs.

ROOM — Early Reflections

Simulates the early reflection patterns of acoustic spaces with adjustable size and distance. Adds depth without the long tail of a reverberator.

DLAY — Delay Cluster

A cluster of short stereo delays after an adjustable pre-delay. Adds body and width with natural separation from the source.

PAN — Delay-Based Panning

Multi-tap delay patterns create robust stereo positioning that holds up off-center and maintains mono compatibility at higher width settings.

DDL — Digital Delay Line

A straightforward single-tap delay with selectable channel routing and up to 360ms of delay time. Simple, clean, and versatile.

RPTS — Repeats

Evenly spaced stereo repetitions that alternate between channels. Adjustable count, timing, and amplitude profile — including a reversed-tape effect.

SCALE — Musical Scale Filter

Comb filters tuned to musical intervals. The left channel locks to A=440Hz while the right steps through a chromatic scale. Dramatic on broadband material.
