Perhaps four days wasn't long enough.

There are plenty of tempo synced delays in the E80, not just in the MFX section, but also as an alternative to the Chorus send parameter...

The drums have many of the other kits' drums available as alternatives. Admittedly, not ALL of them, but for every V-Kit, you get a choice of about 15 different kicks. If that ain't enough, then you may be in trouble. Personally, I've never had an issue with it.

And the floppy is as an ADDITION to USB, and simply serves as a legacy backup for those without modern computers. Yes, it's kind of redundant, but it doesn't substitute for a modern interface, just adds to it. You perhaps didn't mention the 80MB (I think that's the figure) Flash RAM drive onboard, which essentially makes loading times of styles and smf's instantaneous. Far better than a conventional HD, especially as there is little need for a big drive except for MP3's, and those can be put on the Card slot for several GB online.

I'd spend just a bit more time on it to find it's strengths, and perhaps learn that some of the weaknesses you have found don't exist, you merely haven't found the right parameters yet... Perhaps before offering answers to other's questions, you could spend a little more time asking those that DO know the arranger well for those answers yourself?
