Colourcopy

Colourcopy is u-he’s bucket-brigade delay emulation, grown out of the Lyrebird delay module originally built into their Repro-1 and Repro-5 synths. The core of it is a five-colour tonal palette — Resonant, Sparkle, Fuzz, Snap, and Dusk — selectable via a single knob that blends continuously between modes rather than switching. Each colour carries its own character: different frequency bandwidth, noise floor, dynamic behaviour, and the kind of high-frequency rolloff you get as a signal passes through a real BBD chip. A Saturation knob controls how much of that colouration pushes through, and a Brightness control adjusts overall bandwidth.

Delay time runs from sub-millisecond (comb filtering and flanging territory) up to several seconds, and because it models the BBD’s internal sample rate rather than stretching a buffer, pitch shifts when you change the time — smooth and glitch-free, the way the hardware works. A stereo LFO handles modulation across the delay rate, tap positions, or amplitude, and the left and right output taps can be placed independently anywhere along the delay line. There’s also a Freeze button that locks the buffer into a loop, and MIDI note tracking that lets you play pitch-based echo effects chromatically.
