Like I said oddly amateurish for a big name like Eventide (so is their Room 2016 but it's much older). Look at the comparison to the free Oril River:
Notice also the SP2016 Mix is set to 100% yet the tick mark doesn't fall on top of the slider or even at the line in the middle. Makes it kind of hard to visually select exact values. The Bypass and Program buttons look like they fell right out of knobman.
It's not something that would keep me from buying it since the sound is good. I just find it surprising a player like Eventide doesn't have a stronger GUI game.......
