Is now available here: http://www.positivegrid.com/bias-desktop/ Used to be just iOS, now it's for desktop and it had good reviews. Has anyone used this, with any feedback? They make the claim of "The most complete, accurate, and versatile amp modeling software available in the world" I wonder how that stacks up. I'll get to try it out in about 10 hours. It seems to be a Kemper in the box with the amp matching capability....hmmmm....sort of, big difference between source and matched tones actually...so I retract that Kemper statement.
