Hands-On Control

An easy-to-use interface and a rich feature set give you hands-on control over all the details of your sound.

Classic Warmth & Modern Touches

More than a copycat of other hardware compressors, it blends the warmth of classic hardware models with many modern touches.

Colours

Capture the essence of the entire range of classic bucket brigade delays – from the low-range rumbling, slowly evolving delays to the highly resonant, screaming characters. A single knob lets you continuously blend between the five finely-tuned "colour" macros, alongside Saturation and Brightness knobs to dial back colouration or adjust bandwidth.

Flexibility

With delay times ranging from under a millisecond to several seconds, create anything from comb-filter and flange/chorus effects to regular ping-pong delays and longer "looper" effects. Mix or swap input and feedback signals, invert feedback phase, and place left and right output "taps" anywhere along the delay lines.

Animation & Performance Control

Includes a stereo LFO (0.05Hz to 20Hz) with envelope follower modulation, a ducking compressor for either the entire delay output or just the feedback signal, a freeze button that loops the delay buffer for as long as you like, and MIDI key control so you can play Colour Copy like a mono synth.
