The way I see it, apart from the 'stomp' stuff it also lets you program the expression pedal initial value and the 'stomp box' initial value into the patch, which would be useful.
I program that into the Guitar Rig setting.
...and what about the 'bugs' fixed? Have you also no need for those? They do refer to some rare situations indeed.
None of them have ever affected me. Maybe I'm just lucky. 🙂
One more question: can you program the range of the expression pedals to be anything but 1-100%? My EV5 has a button that sets the lower limit and I really like that option, makes it much more usable.
Guitar Rig allows me to program the range for a pedal on a per-patch basis within the software. For instance, I usually set up the volume control to a narrow range of -6 to 0 dB.
I will have to think long and hard whether I like this 5 stomp button thing enough to go Behringer...
Last I looked, there was a huge difference in price between the two. The Roland is easier to set up with Roland devices. The modern Roland units also send patch names to the display on the FC-300, which is nice if you're using a rack unit.
The UnO firmware is cheap enough that you could buy it to try it without fear - if it doesn't work for you, swap back.
