I use this DAW controller in my home studio. I use it mainly to mix songs in Logic Pro, not so much to record.
The initial setup and configuration of the software layer was pretty straight-forward. No complains at all. The default setup, even if it can be altered completely, is simple and useful enough to start working right out-of-the-box.
For the basic stuff (faders, pans, solo, mute...) the unit is very useful and works as smoothly as expected from an SSL product. A minor complain is that the resolution of the faders is "larger" on the UF8 so, even if you move the fader "a lot", at lower volumes, it takes a bit to reflect on the Logic fader. Nothing to worry about, though.
Dealing with sends is a delight, either using the VPOTS or the faders in flip mode. Nothing compared to the smallest-known-to-man Logic control.
At the same time, I use it a lot to manage and fine tune plugin parameters. So far, all parameters from all plugins appear correctly as parameters in the UF8. In this case, though, learning which VPOT does what is a bit frustrating and a bit of a try and error experience.
All in all, I highly recommend this unit if only to avoid being a mouse control freak as I usually am. It helps me focus on listening instead of seeing the mixes.
