■
VALUE (–127~0~127)
This is where you can set the transposition interval in semi-
tone steps. If you wish to transpose a “C” part to “D”, enter
“2”.
Warning : “0” represents the lowest note the MIDI standard
(and the 16-track sequencer) can handle, while “127” is the
highest note. If you select “127” for note number “74 (D5)”,
for example, the resulting note number would be “201”,
which is impossible. Therefore, the sequencer will subtract
“12” from “201” until the result is less than, or equal to,
“127” – and therefore use the value “117” in our example.
Note: Be careful when applying “TRANSPOSE” to a drum
track (track 10 or any other track that uses a Drum Set).
The result may be unpredictable.
■
FROM NOTE (0 C-~127 G9)
This parameter allows you to set the note (or lower limit of
the note range) to be modified within the specified FROM/
TO time range.
It is not displayed when you select “EQUAL”, “UNEQUAL”,
“HIGHER” or “LOWER”. See also “Fine-tuning the setting
range” on p. 113 for details about the six display buttons.
■
TO NOTE (0 C-~127 G9)
This parameter allows you to set the upper limit of the note
range to be modified within the specified FROM/TO time
range.
■
ENTER
Press this display button to confirm your settings and edit
the data.
This function allows you to modify the dynamics
(called “velocity”) of a track or excerpt. Increasing the
velocity values means that the notes in question will
be louder and brighter than before, while reducing
the velocity values means the opposite. You can
decide to add/subtract a fixed velocity value (“BIAS”)
or to change the existing values proportionally
(“MAGNIFY”).
■
TRACK (ALL 1~16)
Allows you to select the track you wish to edit. You can
also select “ALL” here, in which case the operation applies
to all tracks.
■
FROM
●
BAR (1~[last measure of the track or song])— Refers to
the first measure to be edited. By default, the “FROM”
value is set to the beginning of the selected track(s).
●
BEAT (1~[number of beats per bar])— Specifies the
beat position. The number of available beats depends on
the time signature in the selected area.
●
CPT (1~119)— Refers to the starting CPT position. “CPT”
is short for “Clock Pulse Time”, the smallest unit used by
the JM-8. (There are 120 CPT units to every beat of a 4/4
bar.) Change this setting only if your edit operation
should start after the selected beat.
■
TO
By default, the “TO” position is set to the last event of the
selected track (or the last event of the longest track when
you select “ALL”).
●
BAR (1~[last measure of the track or song])— This is
where you specify the bar position of the last measure to
be edited.
●
BEAT (1~[number of beats per bar])— Specifies the
beat position. The number of available beats depends on
the time signature in the selected area.
●
CPT (1~119)— Refers to the last clock that should be
affected by the edit operation. Change this setting only
if your edit operation should not end exactly on the
selected beat.
■
BIAS (–99~99)
The BIAS parameter allows you to specify by how much the
velocity values should change. Select a positive value to
increase the velocity (the value is added to the velocity
value of the affected notes) or a negative value to decrease
the velocity (that value is subtracted). Select “0” if you pre-
fer to work with the MAGNIFY parameter (see below).
This parameter can be particularly useful for velocity
switched sounds: slightly reducing or increasing the overall
velocity allows you to “shift” all notes to the “other” sound.
Note: Even the highest positive or negative value doesn’t
allow you to go beyond “1” or “127”. “0” is used to indicate
the end of a note (note-off). “127”, on the other hand, is
the highest velocity value the MIDI standard can muster.
Adding a high positive velocity value may thus lead to all
notes being played at “127”.
■
MAGNIFY (0~200%)
This parameter works like a “Compander” effect (a dynam-
ics processor that simultaneously acts as compressor and
expander) for MIDI data: by selecting a value above “100%”
you increase the differences between high and low velocity
values in the selected range. Values below “64” are lowered,
while values above “64” are increased. The result is there-
fore that the difference between pianissimo and fortissimo
becomes far more pronounced.
MAGNIFY values below “100%” have the opposite effect:
they push all velocity towards the imaginary center of “64”,
thus reducing differences in playing dynamics.
■
FROM NOTE (0 C~127 G9)
This parameter allows you to set the note (or lower limit of
the note range) to be modified within the specified FROM/
TO time range.
It is not displayed when you select “EQUAL”, “UNEQUAL”,
“HIGHER” or “LOWER”. See also “Fine-tuning the setting
range” on p. 113 for details about the six display buttons.
■
TO NOTE (0 C~127 G9)
This parameter allows you to set the upper limit of the note
range to be modified within the specified FROM/TO time
range.
