Here's what Mellowmuse have to say...
SATV is analogue modelled saturation plug-in with four preset models, perfect for adding harmonic depth and richness to any material. The inspiration for the four preset models were:

• A - Transistor
• B - Transformer
• C - Tube
• D - Tape

Along with 4 selectable saturation models, SATV features Drive, Mix, Output, and an innovative, selectable Group mode.
Group mode allows all instances of SATV in your session to be controlled from any one instance of SATV. For example, setting Drive or saturation mode on any SATV will update all other instances allowing subtle or radical changes to the character of your entire mix from any SATV. SATV's efficient CPU usage allows for high instance counts.
