Hi All; I have not owned a Roland keyboard before so I can't compair Roland to Roland. I traded a Technics Kn7000 for a G 70. I can compair there two. The roland, playing MIDI songs, has a wider range of instraments. On the Technics I hear a "hum" in the background on some songs, but not all. When I heard the G 70 it was through 2 120 watt speakers (240) and I was listening to the KN7000 through the installed speakers (35 watt) so that accounts for the sound difference. The KN7000 will play audio songs and the G 70 will not. The Technics has a proprietary form for storing songs. In my opinion better than MIDI/2.Is one better than the other? I would guess that is up to what you expect from a keyboard. I don't make a living playing keyboards. Would I buy the G 70 again --- yes. On the other hand -- I'm going to buy back the KN7000. There's a place for both in my home. Hope I didn't get too far off track, Dick
