Each time a new release of Sonar is in the offing, I get the feeling that this time support will end for DX fx, and consequently my beloved Sonitus:fx Compressor will die. In anticipation of this day, I force myself to use other compressors (including the Pro Channel ones). I always find myself sneaking back to Sonitus. This is not so much because I sense anything really superior in its sound, but because it is so straightforward to use. The GUI is plain and simple, and it is perfectly clear visually and audibly what your tweaks are doing. I know it is fashionable to say "use ears only" but I find it really helpful to see what is happening, too. Am I missing something with Pro Channel or indeed any other plug-in compressor?
I am only talking about individual track compression here, not bus/mastering applications, by the way.
