Editing the Master Track
The JM-8’s sequencer uses one track called “MASTER”
for each song. It contains the time signature, the tempo,
as well as general SysEx messages that apply to all song
tracks.
Note: You can only edit the MASTER track of songs that
already exist, so be sure to record or load a song beforehand.
(1) If necessary, select the SMF song you wish to edit
(see p. 23 and following).
This is not necessary if you want to edit the currently
selected SMF song.
(2) Select the 16-track sequencer page.
See page 109.
(3) Press the
[MASTER¥TRACK]
display button in the
right column.
This page lists all events already present on the MAS-
TER track. It allows you to modify the existing data,
to delete data you do not need and to add informa-
tion that is missing.
Note: To leave this page, either press the
[BACK]
display
button or the [EXIT] button.
The MASTER track of each Standard MIDI File con-
tains at least the following information:
To change information already available on the MAS-
TER track, proceed as follows:
(4) Use the dial to select the list entry you want to
edit.
The name of the selected parameter appears in the
upper right-hand corner of the display:
(5) Press the dial to select the (first) value.
(6) Modify the value by rotating the dial.
The parameters you can change are:
■
Tempo Change (BPM)
(20~250) Specifies the song tempo. If necessary, you
can insert tempo changes anywhere within the song.
This could even be done in real time (using the
“TEMPO REC SW” parameter). See page 128.
To avoid unpleasant surprises, be sure to save your
song before editing the MASTER track.
Editing existing events
Event Meaning
Tempo This is the “Tempo Change” value located
at 1-01-000. It cannot be erased.
Time signature This is the “Beat Change” value located at
1-01-000. It cannot be erased.
SysEx The “SysEx” string located close to the
beginning of the song. It tells the sound
source what format is being used, how
the effect processors should be set
(types, parameter settings), etc.
Song length The “End of Data” value refers to the
position of the last event (which can be
located on any track) and thus to the end
of the song. This value cannot be edited
manually. You can, however, extend the
song by recording additional data or by
inserting blank measures (page 115).
