Tracy thanx for the wonderful honest review of the Roland EA7...I can understand your frustrations between both units features one has what the other doesn't, I guess that's how they design them as a marketing strategy....
I also have owned arrangers that didn't have just the right styles and had to either create my own, buy third party, and convert styles to suit my needs if possible,....I played Frans EA7 briefly love the layout, & lightweight and hope they incorporate some of those features in the new TOTL arranger if it ever is to be ........
I wish you luck in your music & health..

take care
