Tony,
I'm currently working with my venerable old Korg PA 80 and my Yamaha PSR S750. I have given some thought to saving for a PA 900.
Since I get such good results with outboard harmony I wonder if maybe the PA 600 would suffice. I believe you owned a 600 before getting into the 900. What else would I be missing along with the lack of onboard harmony? Are the styles pretty much the same? Can you record other than midi on the 600? Maybe PM me with your thoughts. Thanks.
God Bless,
Don
