Outgoing MIDI data will be handled with settings
equivalent to
Key Transpose 0, Velocity Curve 4, and
After Touch Curve 3.
Connecting an external MIDI sequencer
or computer
You can play the NAUTILUS’s keyboard and record your
performance on an external MIDI sequencer/computer
(connected via a MIDI interface), and then play back the
recorded performance to sound the NAUTILUS’s tone
generator (i.e., using the NAUTILUS as an input keyboard
and MIDI tone generator). To do this, connect the MIDI
OUT and MIDI IN connectors of the NAUTILUS and your
external MIDI sequencer/ computer to each other.
As an alternative to MIDI, you can connect the NAUTILUS
directly to the computer via USB, using the NAUTILUS’
USB B port.
Local Control On settings
When connections are made as shown above, turn on the
Echo Back function of the external MIDI sequencer or
computer (so that data received at MIDI IN will be re-
transmitted from MIDI OUT), and turn off the NAUTILUS’s
Local Control setting (so that the NAUTILUS’s keyboard
and tone generator will be internally disconnected).
When you play the keyboard of the NAUTILUS, the musical
data will be transmitted to the external MIDI sequencer or
computer, and then echoed back to play the NAUTILUS’s
tone generator. In other words, by turning Local Control
OFF, you can prevent notes from being sounded in duplicate,
as would otherwise occur if a note were sounded by the
NAUTILUS’s own keyboard and again by the data that was
echoed-back.
To turn off Local Control, press the “Local Control On”
(GLOBAL P1: 1–1a) check box to uncheck it.
When using the NAUTILUS by itself, leave Local Control
turned on. (If this is off when the NAUTILUS is used by
itself, playing the keyboard will not produce sound.)
When using Arpeggiator, the Global ARP External
Routing settings and the local control on/off setting will
determine how the function is controlled, as follows. For
more information, see “ARP External Routing” on page 652.
Here are the settings to use if you want an external MIDI
sequencer or computer to record only the notes that trigger
Arpeggiator, and control Arpeggiator using the notes that are
echoed-back during recording or playback.
When Arpeggiator is turned on, playing the NAUTILUS’
keyboard will not trigger Arpeggiator; the notes you play on
the keyboard will only be transmitted. Arpeggiator will
operate only on the notes that are echoed-back and received
at MIDI IN. This prevents Arpeggiator from being applied in
duplicate, and ensures that it will operate correctly.
Here are the settings to use if you want the note data
generated by Arpeggiator to be transmitted via MIDI and
recorded on your external sequencer or computer.
USB MIDI controllers
Overview
The NAUTILUS supports direct connection of USB MIDI
class compliant devices to the rear-panel USB A ports.
Multiple USB MIDI controllers can be connected
simultaneously, if desired.
The NAUTILUS provides no user interface for USB
controllers. Any settings stored in the controller, including
controller assignments, MIDI channel, and so on will apply
in the communication between the controller and the
NAUTILUS. If the controller supports different internal
setups (such as Scenes on Korg devices), you can switch
between them to change the controller’s functionality.
In general, USB MIDI controllers can be used just like
normal MIDI controllers connected to the standard MIDI In
jack (though there are a few limitations, as described below).
If the controller is set to a different MIDI channel than the
NAUTILUS’s Global MIDI Channel, you can use it to play a
different sound than the local keyboard in Combinations or
Songs, as controlled by the Timbre or Track MIDI settings.
You can also play the Drum Track Program in PROGRAM
mode, while still playing the main Program from the
keyboard, by setting the pads to send on the Drum Track’s
MIDI channel (see “Prog MIDI Ch” on page 654).
Bus-powered devices are supported, subject to the current
limits defined by the USB specification. For more
information, see “USB Power” on page 21 of the OG.
Limitations of USB MIDI device support
MIDI clock is not supported from USB MIDI devices.
System Exclusive messages from USB MIDI devices are
limited to 16-bytes. Additionally, certain messages are not
supported, such as mode changes and dump requests.
