I just listened to them all again, one after the other. As I have often said, there are no wrong choices these days.
Just some random thoughts on a rainy night when they won't let me work/play ...
I think I like the overall sound of the Korg best, but each of them has its strong points.
The Korg has the best vocal processor for sure, and I like the guitar sounds a lot. I hit the wrong ending button on it; nothing was programmed there! Korg has the truly wonderful Songbook than no one else has equaled yet. It has some terrible endings. You have to play around some of them. I could edit them, but I'm lazy and shouldn't have to do that.
The Yamaha guitars do a lot of the work for you. Hard to make 'em sound bad. Not sure I like QUITE the level of "help" from the SA voices though. Yes you can choose different ones, but I don't want to have to reprogram every OTS! Even though the new OS is way better, it is still the most difficult to learn and live with. Just my opinion of course.
The Ketron has its own charm. Not sure I used the best drum kit on it. The guitar was more of an acoustic, while on the Roland I used a slight overdrive sound. Neither wrong or right, just different. Eric Clapton doesn't always use the same guitar.
If I could assemble an arranger out of the various parts, I'd use the Korg vocals, the EA7 intros and endings, Yamaha fills and breaks, the flexibility of the Ketron and keys of the Genos or SX or EA7. Others will prefer the semi-weighted feel of the Korg and Ketron.
The EA7 lacks the big touch screen and doesn't display text files, and doesn't have a harmonizer, and has limited fill/break. BUT, I like the keys, the weight, the styles, the ease of operation and the PRICE. I love a few of the sounds. . . sax, organs, a few guitars, one piano, fiddle.
The Genos has that incredible pedal steel sound, and all the sounds are really good. The new drums are much better than ever before, but still not any better to my ears than the Korg. Genos has the vocal oohs and aahs down perfectly. Ketron audio drums are another story; they are just REAL drums.
With AJ's latest work, the Ketron guitars are WAY better than they ever were before.
If the Genos was 61-key length, I would have probably kept it.
If the Korg had lighter key touch, I would be almost totally happy.
If the SD7 wasn't so wide and was a little lighter, and had softer keys, it would be hard to beat.
If the EA7 had . . . ON and ON!
In the words of the great philosopher T. Graham Brown..."Big, little, short or tall, I wish I coulda kept 'em all. MMMM I loved them every one!" No perfect women, no perfect arranger, but there are some really good examples of both creatures.
If you read all this stop by the club and I'll feed you!
