PSP Flow

a new kind of psycho-acoustic compressor

Due to an unforeseen trademark conflict with an unreleased product, we have decided to change the name of our newest compressor to PSP Flare. Please visit a new product page.

In order to run PSP Flare in 30-day trial mode or activate it, you need an iLok user ID which you can create for free at www.ilok.com, and you need to install the free iLok License Manager application but you don't need any hardware dongle.

You can activate the license in 3 separate locations, each of which can be either a computer or an iLok dongle (2nd generation or above). You can move these licenses at any time using PACE's iLok License Manager software.
