u-he Colour Copy review by MusicRadar

Can this analogue-modelling expert bring something new to the party?

Touted as “a virtual-analogue effect inspired by classic bucket-brigade delays”, Colour Copy (VST/AU/AAX) is the latest plugin effect from Berlin’s u-he: a greatly expanded version of the Lyrebird delay module found in their Repro-1 and Repro-5 synths. 

Known for its distinctively dark sound, analogue BBD delays work by passing the input signal down through a series of capacitors to the output, analogous to a queue of firefighters passing buckets of water down the line from one to the next (hence the name). This results in sonic ‘spillage’ with each subsequent repeat, plus saturated echoes with hot input levels. 

Changing the rate at which the signal is passed from capacitor to capacitor alters the delay time with less glitching than digital delays, as well as the pitch of the delays - think dubby, pitch- shifting feedback. u-he’s software emulation aims to bring all of this and more to your plugin- hosting DAW. 

Bucket List
Starting from the far left of Colour Copy’s interface, Input gain (-24/+24dB) is used to drive the signal harder and thus control the degree of echo saturation. Delay rate is set with the Time Base drop-down - choose between four unclocked rates (.001s, .01s, .1s and 1s) or 15 straight, dotted and triplet synced times, ranging from 1/32 to 2/1 - while the bipolar Rate control scales the Time Base value from 1/4 at minimum to 4x at max, and can be swept or automated for those pitch-wobbling repeats described earlier. Change the delay time and you’ll see the delay time period change in the central window - more on this later.

Then there’s the Regen(eration) knob: raise this to progressively route the output signal back into the input for roaring feedback. If that gets out of control, as can easily happen, there’s a handy Panic (!) button to cut off the repeats. Over to the right, you’ve got a trio of self- explanatory controls: stereo Width amount, dry/ wet Mix, and Output (-24/+24dB) gain for setting the final level. 

Tap Dance
The top half of Colour Copy’s green central window displays real-time visual feedback for the left and right delay lines. As mentioned, the horizontal timeline represents the current delay time as set with the Time Base and Rate parameters, with note divisions overlaid on top. Drag an L or R pointer to reposition those taps along the horizontal timelines, and hold Cmd/Ctrl to snap these to those note values. Doing this doesn’t affect the repeat times of either delay line at all, but instead lets you shorten the time between dry signal and echo for L and R independently, facilitating stereo offset effects. These tap positions can also be modulated, as we’ll get to shortly. 

The bottom of the central window is where you customise signal routing. Choose between Stereo, Cross, Mono, Mono-L and Mono-R for the Input signal; and set Feedback routing between Stereo, Cross and Mix. The polarity of the feedback signal can also be inverted with the Invert switch to the right, which is particularly effective at changing the tone when using very short delay times.

Modulation Station 
Colour Copy’s Modulation options enable you to assign a pair of stereo LFOs to the delay Rate or Tap Positions, creating complex and distinctive effects. There’s also the Rate + option, which extends the modulation range in both directions for delays up to four times slower or four times faster. The Amp(litude) modulation destination, meanwhile, allows you to dial in auto-panning or tremolo effects. 

Duck Tales
Perhaps less intuitive but even more useful is the Ducking section in the bottom left, which enables the Regeneration signal to be suppressed whenever the input signal exceeds a set threshold. 

The aim here is to avoid the delay signal overpowering the input, and it’s incredibly effective. In Amp mode, the whole delay signal will be suppressed, but the clever FB mode allows the first delayed signal through unaffected before ducking the rest. Simple, but highly useful. 

CCmein
Unlike straight-up digital delays, u-he’s BBD modelling is designed for smooth, glitch-free changes of buffer length in real time, and this makes Colour Copy a true tweaker’s delay - think dub-style performances and hands-on echo pitch-sweeps. There’s also a cool Freeze option which loops the delay indefinitely. This, like all of the plugin’s main parameters, can be assigned to a MIDI control, expanding the effect’s potential as a performance tool. 

The interface is a little different to other delay plugins, however, and takes a little while to get used to - the way the Rate control and L/R Tap Positions interact isn’t immediately obvious, for example. If you’re looking for a more intuitive design, a plugin such as FabFilter’s Timeless 2 or Soundtoys EchoBoy might be the way to go. That’s not necessarily a criticism of Colour Copy so much as a difference in approach, though, and CC’s sound is worth the learning curve. 

As you’d expect from the creators of outstanding virtual-analogue instruments such as Diva, Repro-1 and Repro-5, Colour Copy sounds utterly awesome at pretty much every setting. From screaming echo distortion to lush chorus and flanging effects and more, it’s an absolute beauty.

Pros:

  • Intuitive interface.
  • Organic, analogue sound.
  • Tons of options for tweaking.

Cons:

  • Time Base/Rate and central panel take a little while to get used to.
  • Other plugins may be more intuitive for basic delay effects.

Verdict:

The German maestro strikes gold again with this gorgeous-sounding, wonderfully creative delay effect. Essential.
