NRPN Dr—This NRPN command is only available for
ADrums tracks. It inserts CC99 value “24”, CC98= “37” as
well as CC06= “64”. While the CC99 value cannot be
changed, the CC98 value can be set to: 37, 38, 40, 41, 52,
56, 57 or 65 (these are note numbers of the drum sounds
whose pitch can be changed). The CC06 value (which
changes the pitch) can be set to 0~127, whereby “64”
means that the pitch remains unchanged.
Editing events
Editing Pitch Bend messages
Pitch Bend messages can be positive or negative (the
range is –128~128). The value “0” means that the
pitch of notes being played in that area is not altered.
If a Pitch Bend occurrence is not reset to “0” at some
stage, all notes will keep sounding flat when you no
longer want them to.
Editing control changes
These messages (CC) can be set to the desired value
(0~127) when the corresponding effect is needed –
but they also need to be reset to “0” to avoid
unpleasant surprises.
About the “Note” messages
As stated above, note messages comprise a note
number, a velocity value and a Gate Time value.
Note numbers can be entered the usual way
([DATA÷ENTRY] dial or [DEC]/[INC]).
The range for note messages is “0 (C–)”~“127 (G9)”.
Velocity messages can be set anywhere between “1”
(extremely soft) and “127”. The velocity value “0” can-
not be entered, because it would effectively switch
off the note.
When you select the Gate Time entry, pressing the
[DATA÷ENTRY] dial calls up the following pop-up:
Use the pad to enter the desired duration. Drum parts
usually use the Gate Time value “1” for all notes.
Increasing it to “20”, for example, has no audible
effect on the sounds.
This message type is only available for melodic Style
tracks (i.e. not for ADrums tracks) and needs to be
inserted by hand (using CREATE EVENT). Style tracks
you only just recorded do not contain it.
It allows you to use a revolutionary system for adapt-
ing the recorded note information to a more natural
behavior (also known as “voicing”). There are two
options:
Degree—This setting refers to the “old” system for real-
time conversion of Style track information for Music
Style playback. Based on the fundamentals of the chords
you play during Arranger playback, it often leads to odd
jumps of certain parts.
Nearest—Refers to a new, more musical, system for real-
time note shifts of the Style tracks/parts during Arranger
playback. Let us first look at an illustration:
This new system is called “Adaptive Chord Voicing”. The
notes of the melodic Style tracks are compared with the
chords played in the chord recognition area. If the next
chord you play contains the note a given part is already
sounding (based on the previous chord), that note is main-
tained.
If the new chord does not contain that note, the Style part
in question uses the closest (“Nearest”) note. In the exam-
ple above, the “G” is closer to the “A” sounded by the
strings part than the “C”. This produces a more musical
behavior than any other system on the market.
Both “Degree” and “Nearest” allow you to specify the note
range (“Limit Low” and “Limit High”) the selected part may
play. Notes that would fall outside that range during
Arranger playback are automatically transposed to values
inside the selected range. Rather than specifying two note
values, you can also choose “Std”, which means that the
G-70 decides automatically when extremely high (or low)
notes need to be shifted down (or up) by one or several
octaves.
Other edit operations
The buttons in the right half of the STYLE MICRO EDIT
page allow you to reduce or expand the number of
events of the track you selected.
