Would someone inform me (George?) whether the G-70's harmoniser (in pitch correct mode, not adding harmonies) will work like Auto-tune (where it detects the pitch you are singing and move/nudge towards the closest 1/2 tone or scalic value) or do you always have to either follow a preset melody or have to play the melody for the pitch correction?

This may be a source of confusion.... many (most?) of us don't like being forced to sing EXACTLY the same line every time we perform the song but if the pitch correction forces us to, this may not be very useful.

If the Roland doesn't do true Auto-Tune, do any of the other arrangers???
