Get a $250 Eventide Channel Strip, Free, for Any Platform - Create Digital Music
A buddy of mine (from college, not part of this community, but knows his shit) posted this on Facebook last night - this is a new Eventide plugin, free until 7/8, $250 after that.
It requires an iLok account (but not dongle), but otherwise is free, and doesn't expire on the 8th. I've done no more than install it, but for the price you can't argue.
Well, that's fucking awesome.
