We love the Eventide H9 multi-effects pedal, it just sounds darn good - especially on synths - that Shimmer reverb makes anything sound awesome - which is a good job given the lack of technique we posses.
There are a lot of other things it does too - time based, pitch based - all manner of excellent sounds for the creative guitarist. However, this new tease for the Crushstation algorithm appears to be more in the dirty department.
Eventide say they will be revealing all quite soon. but here's a screen cap from the video which shows some of the controls.
