Korg NAUTILUS Series

MIDI applications Messages transmitted and received by the NAUTILUS
931
and the X-Y Control, you will normally use the default
settings that are assigned when you execute GLOBAL >
Controllers/Scales– the page menu command “Reset
Controller MIDI Assign” with Default Setting, and leave
ARP Controllers turned Off, X-Y Control X” at CC#118,
and “X-Y Control Y” at CC#119.
If you assign a CC# to ARP controllers, use the same CC#s
as when “Reset Controller MIDI Assign” is executed with
the CC Default setting.
Selecting program/combination banks
Bank select (CC#00, CC#32)
Technically, Bank Select is a controller. In practice,
however, it is a component of Program Change. For more
information, see “Program Change/Bank Select” on
page 929)
Using the joystick to apply modulation
Modulation 1 depth (CC#01) [Bn, 01, vv]
When you move the NAUTILUS’s joystick in the +Y
direction (Vertical upward), Modulation 1 Depth messages
will be transmitted. When these messages are received, the
same effect will be applied as when the NAUTILUS’s
joystick is operated. Normally this will apply a vibrato effect
(pitch LFO).
• In COMBINATION and SEQUENCER modes,
transmission/reception can be switched on/off for each
timbre/track (“Enable JS+Y” COMBINATION/
SEQUENCER 3–1a).
Modulation 2 depth (CC#02) [Bn, 02, vv]
When you move the NAUTILUS’s joystick in the –Y
direction (Vertical downward), Modulation 2 Depth
messages will be transmitted. When these messages are
received, the same effect will be applied as when the
NAUTILUS’s joystick is operated. Normally this will apply
a wah effect (filter LFO).
• In COMBINATION and SEQUENCER modes,
transmission/reception can be switched on/off for each
timbre/track (“Enable JS-Y”
COMBINATION/SEQUENCER 3–1a).
Other manufacturers use this message for other purposes
(e.g., breath controller, etc.)
Controlling portamento
Portamento time (CC#05) [Bn, 05, vv]
If you assign the above CC# to a RT control knobs 1–6
function, rotating that knob will transmit Portamento Time
messages, and will modify the speed at which the
portamento pitch changes. When this message is received,
the result will be the same as when the controller is operated.
Portamento switch (CC#65) [Bn, 41, vv]
When the above CC# is assigned to SW1, SW2 or the
ASSIGNABLE SWITCH, operating that switch will
transmit vv=127 [7F] for ON or vv=0 [00] for OFF, and the
portamento effect will be switched on/off. When this
message is received, the result will be the same as when the
controller is operated. (vv of 63 [3F] or less will be OFF, and
64 [40] or greater will be ON.) (See “SW1/2 Assignments”
on page 913)
• In COMBINATION and SEQUENCER modes,
transmission/reception of this message can be turned
on/off independently for each timbre/track (“Enable
Portamento SW” COMBINATION/SEQUENCER 3–
1a).
• In SEQUENCER mode, portamento time/switch
messages will be transmitted by each track whose Status
is Both, EXT, or EX2 when you set “Portamento” (2–
2a), re-select a song or SMF, or return to the beginning
of a measure. For more information, see “Portamento”
on page 480.
Controlling volume
Volume (CC#07) [Bn, 07, vv]
When the above CC# is assigned to the ASSIGNABLE
PEDAL or as the RT control knobs 1–6 function, operating
that controller will transmit Volume messages, and the
volume will change. When this message is received, the
result will be the same as when the controller is operated.
Expression (CC#11) [Bn, 0B, vv]
When the above CC# is assigned to the ASSIGNABLE
PEDAL or as the RT control knobs 1–6 or as the X-Y CC
control function, operating that controller will transmit
Expression messages, and the volume will change. When
this message is received, the result will be the same as when
the controller is operated.
The volume of the NAUTILUS is determined by multiplying
the value of the Volume message with the value of the
Expression message.
If adjusting the Volume message does not increase the
volume as you expect, or if there is no sound, transmit MIDI
messages from an external device to reset the value of the
Expression message (set vv to 127).
Note: In SEQUENCER mode, this will be reset when the
“Location” of the song is moved to 001:01.000.
• In COMBINATION mode, Volume messages will be
transmitted by each timbre whose Status is EXT or EX2
when you re-select the combination.
• When you change the Volume setting (SEQUENCER 0–
1b) in SEQUENCER mode, or when you re-select the
song or return to the beginning of the song in
SEQUENCER mode, volume messages will be
transmitted by each track whose Status is Both, EXT, or
EX2.
Note: Regardless of the Status settings, re-selecting a
song, or returning to the beginning will reset the internal
Volume value to the value specified by each track (the
starting settings), and will reset the Expression value to
the maximum.
Note: This message can be used to control the volume of
each MIDI track. Normally, you will include a Volume
message in the MIDI track setting data (the settings at the
beginning of the track) to set the initial volume, and use
Expression to create changes in dynamics as the song
progresses.
By using the universal exclusive Master Volume message,
you can adjust the overall volume without changing the
volume balance between timbres or tracks (see “About
system exclusive messages” on page 934).
