I no longer own the PA. I sold it and am waiting for the Tyros to come in. I reviewed my feelings about the PA on Harmony central, so you could go there if you wish to read my thoughts as well as others opinions as well. http://www.harmony-central.com/Synth/Data/Korg/PA-80-01.html

I do still have the T Rack though. Here are my general feelings. Korg products I think are capable of alot, however I think along with that comes a more complex interface. I have not found any of the Korg products I have owned that intuitve, in comparison to others I have owned. Does not mean it can't be done, I just think more difficult to ME on Korg.

The second observation to me is again in an A/B comparison to any other boards I have heard Korg has a harder more dance/techno sound, including the PA.

Lastly I found the RPPR function very difficult to work with and neither the dealer nor Korg was much help when I contacted either.
