Nice demo. When it comes to key feel & acoustic piano sounds, Roland definitely has the rest beat.In addition, What I notice right off on the G70 is it's chocolaty rich overall sound. The mid-upper registers though seem to lack the clean sparkle I appreciate on Yamaha & Korg arrangers. The only thing that's kept me from the G70 is the lug around weight and that it doesn't recognize jazz chords the way the other arranger manufacturers do. - Scott
