The CL 1B Mk II plug-in is available for Windows 7+ (64-bit) in VST, VST3, or AAX (Pro Tools 10.3.7, 11.0.2 or higher), and for Mac OS X/macOS 10.9+, all of the above plus AU. You will need both a Softube/Gobbler account and an iLok account, although a physical iLok key (generation 2 or 3) is not vital—you can authorize one computer’s hard drive to use the plug-in and skip the dongle if you prefer.

Everything I’ve described above and experienced in the hardware is 100% applicable to the new plug-in. As with the original Mk I plug-in, every knob, switch, and meter is an exact replica of the hardware. On the new version, the GUI is more photorealistic and almost three times bigger in size than that of the original (which is shown in the screenshot later in this article and is included with the new version). I used the new plug-in with a Slate Raven controller, and the larger GUI and knobs make for a very satisfying faux-tactile experience.

In the plug-in, there is one functional limitation compared to the hardware: the sidechain only offers one output or bus choice. However, it can function like the hardware if your DAW supports external sidechaining.

There are also two added functions available only in the software version. First, there’s an internal lowcut-style sidechain with settings of 80 or 220 Hz; this allows signals below those frequencies to pass through the detection circuit without clamping down. Second, there’s a wet/dry mix control, allowing for “in the box” parallel compression techniques. Both of these features, along with the fact that the Softube CL 1B Mk II can be launched as a stereo plug-in, make it very well suited to bus work.
