Little MicroShift is anything but little. It adds massive width, enormous depth, and huge thickness to vocals, guitars, synths, whatever. Emulating three of the most sought after micro pitch-shifting sounds from two of the all time classic pieces of gear that made the technique famous (including one our designers created "wink"), Little MicroShift puts them right at your fingertips. All you have to do is find a code and this little slice of studio sweet sauce is yours.

Pretty cool, and they're getting around to releasing 64bit versions of the plugins (CANNOT WAIT)
