Softube Releases Native Format Tube-Tech CL 1B Compressor

Swedish company Softube has begun shipping a native format plug-in version of the Lydkraft/Tube-Tech CL 1B Compressor, the highly revered hardware unit that has been a staple in pro recording studios for more than two decades. The special launch price of $299.99, which is in effect until October 31, 2009, is intended to put the new native CL 1B plug-in within the reach of DAW-based recording musicians.

Softube created its first software emulation of the CL 1B for the TDM and TC PowerCore platforms. The native version features the same painstakingly-constructed modeling algorithms, with additional features. Softube doubled up the capabilities and enabled the unit to operate in stereo. (The left and right channels are linked for phase accuracy.) A new external sidechain input lets users trigger the compressor from the selected source audio for creating classic effects such as locking the bass compression to the kick drum. (Note that RTAS and Audio Units hosts support sidechain inputs; check your VST host to determine if this feature is implemented.)

The hardware CL 1B has always been prized for its pure, uncolored, natural compression. Tube-Tech designer and president John Petersen says that Softube’s native CL 1B is “a truly faithful and very exact replica of the hardware CL 1B. Finally it’s possible to experience natural musical compression in a plug-in.”

The CL 1B plug-in is designed for use with Mac and PC, and with VST/Audio Units/RTAS-compatible host DAWs. Through the month of October 2009, it is being offered at a discounted introductory price of $299.99. On November 1, 2009, the price will revert to $399.99. The plug-in is available for purchase at all authorized MV Pro Audio dealers. For a list of dealers, visit
