The upper "Phrase" parameter selects the source phrase — i.e. the user phrase
from which the data is to be copied: "001" ... "100".
The lower "Phrase" parameter selects the destination phrase — i.e. the
user phrase to which the data is to be appended: "001" ... "100".
After setting the parameters as required press [ENTER] to execute the Append
Phrase job. The metronome icon will appear on the display while the data is
being processed, then "Completed" will appear briefly when the job is done.
Press the [F6] key ("Exit") to return to the job list, or a mode key to go directly
to the selected mode.
Splits a specified user phrase into two parts at the specified measure, and
moves the latter half to another specified user phrase.
The upper "Phrase" parameter selects the source phrase — i.e. the user phrase
which is to be split: "001" ... "100".
The "M" parameter specifies the measure at which the source phrase is to
be split: "1" ... "8", depending on the length of the source phrase (if "1" is
selected the entire phrase is moved to the specified destination).
The lower "Phrase" parameter selects the destination phrase — i.e. the
user phrase to which the latter half of the split source phrase is to be moved:
"001" ... "100".
