I have to say that the PA 1000 is absolutely spectacular. It maps so well from the 3X and I hear some really cleaned up styles that are so fun through monitors.
I am thrilled that I gave it a thorough look and excited to take it live.
Mapping was tedious the first day (3 - 4 songs and lost all, etc), but now, in 3 days, I have a about 4 full sets done. It's a joy to start fresh on a new keyboard and get super organized too.
Enjoy your 1000 - I sure changed my mind.
