This sets the highest key (upper octave limit) of the note transposition for the
chord root change. Any notes calculated to be higher than the highest key are
transposed down to the next lowest octave. This setting is available only when the
NTR parameter (page 22) is set to "Root Trans."
Example—When the highest key is F.

Notes played
These set the note range (highest and lowest notes) for Voices recorded to the
Style channels. By judicious setting of this range, you can ensure that the Voices
sound as realistic as possible—in other words, that no notes outside the natural
range are sounded (e.g., high bass sounds or low piccolo sounds).
Example—When the lowest note is C3 and the highest is D4.
