JV-35, JV-50: Split Mode

Split mode allows the keyboard to be split (divided) into two zones at a
specified point (Split Point). It is then possible to play a different Tone in
each zone. All keys above and including the Split Point form the Upper zone,
while the keys below that make up the Lower zone. The following is how to set
the Split Point:

1) While holding the SPLIT button, the current split point will be shown.
2) While holding the SPLIT button, make the setting for the split point using
the VALUE buttons.
3) Release the SPLIT button and the Split Point will be stored in memory.
