Korg NAUTILUS Series

PROGRAM > Home 0–8: Sampling
27
Send1 (to MFX1) [000…127]
Send2 (to MFX2) [000…127]
These adjust the levels at which the external audio input
signal is sent to the master effects.
Send1 (to MFX1): Send the signal to master effect 1.
Send2 (to MFX2): Send the signal to master effect 2.
If Bus Select (IFX/Indiv. Out Assign) is set to IFX1–12,
the send levels to the master effects are set by the post-
IFX1–12 Send1 and Send2 (8–2a). For more information,
see “Analog, and USB inputs” on page 745.
MUTE [Off, On]
Turns on/off mute for the external audio signal being
inputted.
On: The input sound will be muted (silent).
Off: The input sound will be heard.
Solo [Off, On]
Turns on/off Solo for the external audio signal being
inputted. It does this by temporarily muting all non-soloed
Oscillators and audio inputs.
The way in which Solo operates depends on the setting of
the Exclusive Solo menu command.
The Solo setting is not stored when you Write a Program.
Pan [L000…C064…R127]
This specifies the panning of the audio input. When using
two inputs for a stereo audio source, you’ll normally set the
inputs to L000 and R127 respectively.
Level [000…127]
This controls the level of the external audio signal. The
default is 127.
The meter to the left of the slider shows the audio input
volume, before the Level control, in realtime.
The analog audio signals from AUDIO INPUTS 1–2 are
converted into digital form by an A/D converter. This
parameter sets the level of the signal immediately after this
conversion.
If the sound is distorted even though this level setting is very
low, see “Tips for eliminating distortion when using the
analog inputs,” below.
Avoiding extraneous noise
If audio cables are connected to AUDIO INPUTS 1–2,
any noise carried by the cables will enter into the
NAUTILUS mixer structure. This may include hiss, hum,
and other audio noise.
To avoid noise from unused audio inputs, either:
• Set the input’s Level to 0
or
• Set all of the bus assignments to Off, including Bus
Select (IFX/Indiv. Out Assign), REC Bus, and FX
Control Bus
If no audio cables are connected to AUDIO INPUTS 1–2,
the input signals are forced to zero, preventing any
additional noise.
0–8c: Rec Level [dB]
ADC OVERLOAD!
If the signal level from the analog audio inputs is too high,
the “ADC OVERLOAD!” indication will appear. You’ll
need to adjust Audio Input Setup, or the output level of your
external audio source.
Recording Level [–Inf, –72.0…+0.0…+18.0]
This adjusts the signal level at the final stage of sampling.
The Recording Level setting is made for PROGRAM mode
as a whole, and is not saved independently with each
Program.
Level Meter
This shows the signal level at the final stage of sampling,
after any adjustments on the Audio Inputs page, any effects,
etc. The meter is active only during standby mode and
recording.
CLIP!
If 0 dB is exceeded, the display will indicate “CLIP!” This
means that the level of the sampling signal is too high; in this
case, adjust the Recording Level, and if necessary follow the
instructions under “Tips for eliminating distortion when
using the analog inputs,” below.
Setting levels
For the best results, set the levels as described below:
1. Press the SAMPLING REC button.
NAUTILUS will enter sampling standby mode, and the
Level Meter becomes active.
2. Initially, set the Recording Level to 0.0dB.
3. Adjust the level of the input signal so that it is as high
as possible without activating the CLIP! or ADC
OVERLOAD! messages.
If you’re using AUDIO INPUTS 1 and/or 2, adjust the
volume by Analog Input Setting.
If you’re using AUDIO INPUT 3 and/or 4, adjust the output
level of your external audio source.
If you’re sampling external audio through the internal
effects, you may also need to adjust the individual effects
input and/or output level parameters.
If you’re using internal sounds, adjust the levels using the
effects input/output trim, etc.
4. If the level is still not high enough, increase the
Recording Level using the on-screen slider.
Again, the goal is to get the level as high as possible without
activating the CLIP! or ADC OVERLOAD! messages.
Tips for eliminating distortion when using the
analog inputs
If sound from the analog inputs is distorted, but the CLIP!
message doesn’t appear, it’s possible that distortion is
occurring at the analog input stage, or that distortion is being
caused by the settings of the internal effects.
If the “ADC OVERLOAD!” message appears above the
Recording Level meters, the distortion is due to excessive
levels at the input. In this case, either lower the output level
of the external audio source, or adjust Audio Input Setting so
that this message does not appear.
