SKnote has released Mattertone, a multiband, level-independent envelope shaper plug-in.
With Mattertone you can manage attack and sustain for each band (lows, highs and parametric mids), without thresholds or triggers. You can tame resonances, sculpt the sound, remove reverb, create huge rooms from drums recordings and more.
Mattertone is available for 32- and 64-bit Windows and Mac OS X in VST, AU and RTAS formats for $29.99. It is also available bundled with Grasso.
