Hi Nick,

Your best bet would be to post your questions on the Roland arranger site.

As far as I know, the keybeds are different between the E-80 and G-70 (not just the number of keys) although they both have aftertouch, and, the E-80's latest OS upgrade included an MP3 player.

I played them both, and I liked the E-80 more than the G-70, although both have a bender/lever that I didn't like much, preferring separate pitch/mod wheels myself.

You should also consider parts availability in the future, as these instruments have been out a while, although both are excellent and well made arrangers.

Ian
