Song Memory Function
Editing Data While Step
Recording
Memory data can be thought of as a musical score that
progresses from left to right, with the input point normally at
the far right of the recorded data. The following procedure
describes how to move the input point to the left in order to
make changes in data you have already input. Note, however,
that moving the input point to the left and changing data
automatically deletes all of the data to the right of the input
point.
To edit data while step recording
1.
While a step recording operation is in progress,
use the FF and REW button to move the input
point to the location where you want to edit the
data you have already input.
If notes are already recorded, each press of FF or
REW moves the input point to the next successive
note. The data recorded at the current input point
appears on the display.
If notes are not recorded, each press of FF or REW
moves the input point to the next successive beat.
E-44
If you move from an area that contains note data
to an area that does not contain note data, each
press of FF moves the input point to the next beat.
Pressing the REW button, however, causes the
input point to jump back to the location of the
first note or rest to the left.
2.
Press the [+] and [–] buttons.
3.
Press the [+] button to start the data editing
operation or [–] to clear the data editing screen
without changing anything.
Pressing the [+] button automatically clears all
data to the right of the current input point. Next,
the keyboard stands by for input of step
recording data.
Pressing the [–] button clears the data editing
screen and returns to the step recording screen
where you can move the input point.
The message [TrackEnd] appears on the display when the
input point reaches end of the current data stored in Track
2. At this point you can perform steps 2 and 3 to add more
data.
