7. Move the cursor to "SMOOTH" and specify the
correction speed.
fig.03-3683d
SMOOTH
The value set here is added to the value of the "Smooth"
patch parameter (p. 134).
When set to "0," the correction speed is the same as that
set in the patch's "Smooth" setting.
As the value increases in the negative direction, the pitch
correction is executed more rapidly than it would be
according to the value set in the patch, whereas the
correction is applied more smoothly as the selected value
is increased in the positive direction.
* Set the value so that the sum of the values is in a range from 0
to 100. The pitch correction produces no effect when the value
is set below 0 or over 100.
8. Press [F1] (NEW).
Another new correction event is inserted.
9. Move the cursor to "TIME" and specify the time at which
you want the correction to end with the TIME/VALUE dial.
fig.03-369d
10. Move the cursor to "NOTE" and specify "OFF."
fig.03-3682d
11. Have the Recorder play the song from the beginning.
When a correction event specifies the note name in
NOTE, the correction is first applied at the point in the
song specified in Step 5, with the correction ending at the
point specified in Step 9.
12. To delete any unnecessary correction events, move the
cursor to the event and press [F3] (DELETE).
The correction event is deleted.
You cannot delete the correction event at the beginning
of the song. If this correction event is unneeded, rather
than deleting it, just set the function to "OFF."
13. Repeat Steps 4–12 as needed to specify the edited range.
14. To save the correction events you have input, save the
song (p. 70).
You can only save a Correction Event Map to a
single song. Even if you switch the patch with the
pitch correction, the Correction Event Map remains
unchanged.
