A virtual analog effect inspired by classic bucket-brigade delays (bbd), but extended with modern features. We called our new baby “Colour Copy” because it can deliver the kind of colouration people still love in classic bbd units, but with a wider variety of colours. Colour Copy started life as the little delay unit called “Lyrebird” we built into Repro-1, but the sound was too good not to be developed further and become an fx plug-in.
Features
Colours
During development we soon realized that we could 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. The differences may be subtle, but each one is rich in detail. In addition to obvious differences in frequency bandwidth, each comes with its own noise and dynamic characteristics, frequency loss over time, and several other qualities. The Saturation knob controls how prominent or subtle those characteristics should be, in case you want to dial back the colouration to better fit in the mix. Finally, a Brightness knob lets you adjust the bandwidth.
Flexibility
Colour Copy is capable of a huge variety of different delay-based effects. With delay times ranging from under a millisecond to several seconds, you can create anything from comb-filter and flange/chorus effects to regular ping-pong delays and longer “looper” effects. The routing options let you mix or swap the input and feedback signals independently or even invert the feedback phase for various phase cancellation effects when delay times are set very short. Additionally, unlike hardware BBD units, Colour Copy’s left and right output “taps” can be placed anywhere along the delay lines. This feature lets you move echos independently “forward in time” for e.g. ping-pong or “rushing” delays as well as various stereo chorus or flanger effects. You never knew you’d want three different ways to create a ping-pong effect!
Animation
Colour Copy comes with a stereo lfo that can be used to modulate either the delay rate, the tap positions or the delay amplitude. With a range of 0.05Hz to 20Hz (as times: 20s to 50ms) the lfo can create chorus, vibrato and tremolo effects. Crank up the modulation depth for deep pitch-shifting. An envelope follow signal derived from the input signal can be used to modulate the lfo frequency and depth, adding realtime dynamics to the effects.
Colour Copy comes with the obligatory ducking compressor, but with a unique twist: You can select whether to duck the entire delay output or just the feedback signal. This latter option leaves the very first delay unaffected, preserving the overall stereo “space” while preventing the sonic mayhem that high regeneration often causes.
Performance Control
Some people like to perform on their bbd hardware, pitching the regeneration up and down by twisting the rate knob. We took Colour Copy a step further in this direction by adding a pair of creative features: Firstly, a freeze button that loops the contents of the delay buffer for as long as you like. Secondly, midi key control so that you can play Colour Copy like a mono synth – each octave up doubles the delay rate.

HAPPY NEW YEAR!!!
Release by VR timebombs. VR tried to force-validate serial by old routine by
patching but it doesn’t really help. We checked their Hive2 release and we
found zero timebombs are patched. Now you know that users who posts “100
percent working” for their releases are zero percent trustful.
At least we checked many places they haven’t noticed.
Let’s hope we made 100 percent again this time 🙂
—————————————————————————-
Here is how U-he main protection works:
1. Generate value (0 – 2047) from the licensee name.
We call this value “UserValue”.
2. Get the hash of serial number by UrsHash.
UrsHash is combination of WHIRLPOOL512 and SHA512)
3. Get hardcodedHash[UserValue] and compare with calculated hash.
If it matches, license = OK.
This means, serial number is not generated for users dynamically. The hash
of all serial numbers are hardcoded to the app since the first release. User
name is just used to determine which correct serial number to assign. This
is good if dev has many customers, otherwise serial check will be dull and
slow (check all hardcoded serials one by one, this is done by RobPapen).
However, there is the weak point in this “wise” protection. Once legit serial
numbers are leaked, that serial number can be used to other name. You can
make another licensee for that serial by colliding “UserValue”. This is not
easy to avoid. Blacklisting the leaked serial number can affect to the legit
users too, because that user may have same UserValue with leaked licensee.
In short:
– Uhe app contains 2048 correct hashed serial numbers.
– Calculate valid serial from hashed serial is nearly impossible.
– User A and User B may have same legit serial number.
-> Generate another valid name for leaked serial can be possible.
Enjoy checking many security aspects for the uhe type protection.
These UserValue+Hash protection is used by Arturia, Audiority, SonicAcademy,
LVC-Audio, Youlean etc. Valid user+serial pair can be made from legit serial.
