That's possibly the strongest point (well, OK, ONE of the strongest points!) of the G70 over the E60, Cassp... Hit one button, and all the sliders are IMMEDIATELY active as voice editing sliders. So the 'instant gratification' thing is just as high as a Juno106, ARP, etc..

Me, I'd want this LONG before I gave a hoot about the stupid harmonizer....

In the meantime, all those editing possibilities have MIDI CC controls, so a nice cheap MIDI fader/knob controller would give you the tactile 'instant gratification' you look for, without ponying up for a G70.
