Tube-Tech CL 1B Compressor
Foreword by John G. Petersen
After several years of consideration, we
decided that the time had come to introduce a
plug in of our TUBE- TECH CL 1B.
The development of the plug in was initialized
in November 2006, as a co operation between
Lydkraft, Softube and TC Electronic. Hear-
ing the result, we found that Softube was able
to reach the difficult goal of making a plug in
of the CL 1B which came extremely close to
the original sound and gave the user all the
characteristics of the hardware. After very
serious testing of the software, the plug in was
released late 2007.
To take this project one major step further,
we decided in early spring 2009 to release a
VST/AU/RTAS version of the plug in, and
once again placed the developing task in the
hands of Softube.
We are very impressed by the skills of these
young guys from Sweden and we feel excited
that the quality of the CL 1B is now avail-
able for all workstation users.
We hope you will enjoy the excellence of the
TUBE -TECH CL 1B plug in.
Yours sincerely,
John G. Petersen
President, Lydkraft/Tube-Tech
About the CL 1B
The hardware CL 1B differs from many other com-
pressors in that the gain reduction element is made
from a non semiconductor component, which in
itself has a very low harmonic distortion and none
of the non linearity problems involved when using
most semiconductor elements. All parts of these
equally important design choices have of course
been painstakingly modeled when creating the CL
1B plug in.
Another thing that is special about the CL 1B is
the Attack/Release Select switch which allows the
user to switch between a manual and a fixed attack/
release setting, but also makes it possible for the
user to combine both the fixed and manual settings.
This gives a feature not normally obtained in other
compressors: In the combined mode the attack and
release controls makes it possible to obtain complex
program dependent release time slopes where a fast
peak results in a fast release and vice versa.
