Diki,

The E-50 is no where near the PSR-S900...no SA voices, no Mega voices, no rootless chord recognition(which I use...you obviously have no need of it)no Audio to USB...in fact the G70 has none of these features either.

IF Roland improves the breed enough to provide at least the equivalent of these features it would make it worth having one as a diversion.

As they are presently, it would be too much of a step backward to use one, even as a backup.

I hope the new G series has more to offer.
