While I don't consider Saturn a true "exciter/enhancer" I probably should.  It is one cool tool that will cover quite a number of bases.  So...add it to my list as well.

Totally missed Fabfilters Saturn:) Sound great!

Thanks

PSP Mixpack is very interesting, because it provides you with several tools for the price.   You get, "Mixtreble," but you also get MixGate, MixPressor, MixBass, MixSaturator, and MixSync...

Mixtreble rocks on Hi-Hats, ad leads with heavy reverb.

MixPressor is a very versatile comp, which covers too many areas to list
MixSaturator is like, "the first console emulator," but can be pushing for, "a distortion box."

MixBass is self explanatory

and MixGate has bugs!!!!!!!!!!!!!!!!!!!!  ( Renoise related..  wont accept automation commands from the pattern editor.  )

MixSync is a plugin compensation device...  I haven't needed it...

Linear Phase - yeah, you get some really good tools in this box:) 

PS - I haven't produced/mixed music for that long, so I am learning bit by bit how to use different FXs in the mix. A lot of great online tutorials and user forums like this one is getting me there faster;)
