Had mine delivered yesterday. Dayton Ohio area. Did a quick setup....will be playing with it Thursday at band practice and then Sunday at three services at church, so should have a better feel after that.
As others have stated, in person it's a bit smaller than you expect. One note...when you hook up for the first time, it goes thru an update sequence. It takes a few minutes and then you are good to go.
Also, need to spend some time on 'workflow'. I can see how to set the performance mode and it loads the presets, but I can't see how to view the available/assigned effects in that mode...or if it's possible. In browse mode on the KPA, it just goes up/down thru the whole list of presets. Which is nice...if you don't have 100s of presets. I might have to take off all my non-favorites and just keep a handful.
The looper is pretty fun. Tuner works well. Tap tempo works well, plus the beat detect (when you hold the tap tempo button down) works very well. We do some songs where the click starts right after the previous song and it's hard to tap in and then play so the beat detect might get some more use.
