Renoise, on the Ubuntu 64-bit distribution of Linux. (Note. 32-bit is recommended, if you need compatibility with non-opensource.)
As you know, there has been a shortage of fully professional mastering-limiters on Linux.
However, I can happily announce the availability of one now. And it is opensource and licenced under the GPL.
(So if you want to compile it on SPARC, you can!)
Please visit www.sourceforge.com/projects/pxu
A track demonstrating the plugins can be downloaded here: [Space Marley 2010.xrns](http://www.paradoxuncreated.com/Pxu/space marley 2010.xrns)
