Two more cents worth - I reeeeeealy wanted to love the PA80. I have been a Korg user, and I'm very used to the way they work, sound, feel, etc..... The PA80, I believe, is STILL a work in progress. Maybe they took the best workstation features from the Triton line and added some scaled down arranger stuff, but they didn't do ALL their homework. The button layout, menu items, and general ergonomics are not up to par with the current status of what solo players need.
I gave mine a good test drive, and I realized early on, that there were too many "missing pieces" to the puzzle. I think the drums sound great, as do most of the staple sounds, but the "ease of use" factor is way off target. Anyone that has played an earlier I series, or PSR series, or any Roland series would find it very uncomfortable, and unnecessary to learn a new technique for controlling basic functions in a "real time" setting.

Two examples:

Try to change the tone of the manual bass part. You need to select the manual button first, then call up the bass tone section, then DEselect the manual button, and REselect it before the change takes place. What egghead designed THAT?

Next - try to change the volume of the arranger bass part during playback, by just a Teeeeny bit at a time. You can't do it. You need to go into the mixer menu, and then the volume will step up or down in small increments - too much time - too many button pushes - to much lost "fingers on the keys" time. Solo entertainers need 3 pairs of arms to do what we need to as it is - we need the button pushes to be kept to a minimum. The PA80 does not play well in a live, solo situation. It needs lots of work on the o/s before it can be a contender, and that I why I rated the PSR2k ahead of the Korg.

Potential buyers of arranger keyboards need lots of flexibility, and the Korg is way too "button intensive" to be an easy piece to find comfort with.
Maybe a few more o/s updates can bring it up to the level that they are charging you for, but at his time - the PA80 is a much better workstation, than it is an arranger.
Hmmmmmm, wasn't the Triton ALWAYS a pretty good workstation? I think Korg pulled a fast one on us, but I for one, wasn't fooled.

BTW - My friend just traded a mint I30 - anyone need one? I'll post the details in the "for sale" section as soon as I find out if it has a HD or not.
