Donny, wasn’t the E-80 pretty much a 61 key version with some funky onboard speakers version of the G70. (I know Fran is the expert on this topic)
I just remember on the original demo...the orchestral demo had a very robotic timpani roll, which was kind of a turn off.
The guitar software was pretty cool though.

It was one of the few Roland arrangers I never had the pleasure of owning...
