It's official - I NEED to use the digitech harmonizer for ALL jobs that are more than background music, or a 1 hr senior show.
I hooked it up today with the PSR9k, and my life was so much easier. Ahhhhh, relief. Too bad this now means that the 9000 is again incomplete. I still plan to keep it "on line" until a new option arises - nothing out to date will replace it for me yet.
I was very pleased (NOT surprised) at how the digitech sounded thru the Yammy speakers. It was wonderful. This means I MUST bring at least a small rack bag now, but that is not so bad - I have lots of options in that area.
Quick report card:
PSR9k-
1)sounds - A+
2)styles - A-
3)EZ to use - A+
4)size - D
5)weight - F
6)controllers - A+
7)price - B-
8)reliability - A
9)mic effects - A-

Overall grade - a strong B+, maybe A-
In a home situation(NO travel), or for a non singer - it's a sure fire A.
