Well in the new battle for who is the top dog in the DSP world, TC Powercore who features Sony Plugs has now added the Transient Modulator to there bundle.

This is basically a Sony version of the Creamware SPL Transient Designer for the most part.
I gotta say, TC is pushing they're platform hard all of a sudden..
