I found the EA7 editing pretty deep to tweak all perimeters.......
maybe I am missing something. ?

If you're referring to the E-A7 I find this surprising Dave. Pages 29-33 of the Reference Manual imply that you can do a lot more sound editing on the E-A7 than you could on any previous Roland arranger.

I'm not into sampling or creating my own sounds. But with that kind of editing ability and so many base samples to choose from, I would think that the E-A7 is pretty good in this regard.

The E-A7 has a lot of editing capabilities.. as deep as anyone and yes much more than previous Roland arrangers.

The one thing that maybe Dave doesn't understand , They reserve the primary tones to edit and if a tone is a variation of the primary ..you should use that primary to begin edits..When it says you can't edit the tone, that is what it refers to.

Dollar for dollar ..E_A7 is the best arranger on the market.. There is a learning curve , and most folks won't learn..

EA7 for me was another Love/hate relationship..
but overall more love then hate.

There were at least 4 or 5 tones I tried to modify and got the message "This tone cannot be edited"
I actually understand that.
