6. Tempo Sync
Value: OFF, , ,
x1 – x4
Set this when synchronizing the Rate setting to the
song tempo. When not synchronizing, set this "OFF."
When you select the note, the Rate setting is disabled,
and the Rate is set the note length corresponding to
the song tempo.
If the length of the note is set longer (or shorter)
than that of the possible range of the Rate settings
by the change of song tempo, the Rate can not
correspond to the note length. If "?" appears before
the note symbol you set, it is because the upper (or
lower) limit of the setting range has been exceeded,
and that the synchronization is not correct.
Furthermore, the precision of the Rate setting and
song tempo differ. If left to develop over long
periods, the two may gradually drift apart.
7. Modulation L-R Phase
Value: NonInv, Inv
This sets the phase when the chorus or flanger sound
is mixed in with the source sound in the left and right
channels. When this is set to NORM, the channels are
in phase; when set to INV (inverted), the phases of
left and right channels are inverted relative to each
other.
