I don't recall that being a primary reason for me to change boards before. I am quite familiar with Yamaha and Ketron OS. And I did spend the time to make the G70 "my own", even though it wasn't. I may have said that about the Tyros 2, because to make it sound more like the "live" sound I'm looking for would have taken a lot of time.
I tend to change keyboards about once a year, although last year was a big exception.
I actually played the PSR2000 for more than two years!
In the case of the PA800, there is the time involved, which I mentioned. Some of this is related to the manner in which lyrics are entered. They must be placed into a Songbook file for each song. I have many hundreds of lyrics and I don't want to do this. Of course I don't use most of them most of the time, but I do want them available. Currently I use a laptop for this, and I would like to eliminate that from my setup if possible.
From the keyboards and setups I've tried, the Ketron Midjay comes closest to what I need, and that's probably what I'll use until the next great thing comes along.
Meanwhile, you can take advantage of my foolishness by getting a killer deal on a PA800!
