Korg NAUTILUS Series Operation Manual page 137

Auto +12 dB On
In general, the Recording Level should be set to 0 (dB). For
more information, see "Setting the recording level" on
page 128.
In order to maintain headroom, the NAUTILUS generally
plays back samples 12 dB softer than the original volume (if
+12 dB is off). This is appropriate for sounds which will be
played back polyphonically, such as samples of acoustic
instruments.
For drum loops and similar material, on the other hand, you
may wish to play back the data at the same level at which it
was sampled. In this case, turn on the +12 dB parameter
(SAMPLING > Loop Edit page).
If you sample with the Auto +12 dB On setting checked,
+12 dB will automatically be turned on, and the recorded
sample will play back at the same level at which it was
sampled.
Sample to Disk (Bit Depth)
When Save To is set to Disk, you can choose to record at
either 16-bit or 24-bit resolution.
When Save To is set to RAM, the resolution is fixed at 16-
bit.
Optimizing RAM memory
Optimization rearranges any unused memory areas so that
all of the remaining memory can be used, which may
increase the amount of RAM available for sampling. This
optimization can happen either manually or automatically.
Automatic optimization is enabled via the Auto Optimize
RAM parameter on the GLOBAL > Basic Setup page. When
this is turned on, RAM will automatically be optimized
when sampling ends.
This option will keep the greatest amount of RAM free for
sampling. However, it requires a little time to work, and so
the sound will stop for a time after sampling ends. Also, if a
song is playing in SEQUENCER mode, the playback will
stop.
Because of this, if you're playing back a song or recording
multiple samples at once, it's probably better to leave Auto
Optimize RAM turned off. Once you're finished sampling,
or if you notice that the amount of available RAM is getting
low, use the Optimize RAM menu command to do the
optimization manually.
You can check on the remaining amount of memory in
SAMPLING mode on the Recording page, under Free
Sample Memory/Locations. For more information, see "0–
1f: Free Sample Memory/Locations" on page 579 of the PG.
Using the metronome
The metronome can be helpful when you want to play a
Program or Combination at a specific tempo and sample
your performance.
You can make metronome settings in Metronome Setup, in
PROGRAM or COMBINATION > Home– Sampling: Audio
Input page. You might find it convenient to set Bus
(OUTPUT) Select to one of the Indiv. 1–4 outputs, connect
the (individual) 1–4 jacks to a mixer, and monitor the
metronome via your mixer.
Preparations for sampling Audio Settings
Automatically setting-up for the desired
sampling method (Auto Sampling Setup)
In each mode, Auto Sampling Setup automatically makes the
appropriate settings for the sampling-related parameters. For
example in PROGRAM mode you can use this to make the
necessary settings for resampling your playing on a program,
or to make settings for sampling only an external audio
source while you monitor your playing on a program.
However, these automatic settings assume typical situations,
so you'll need to adjust the parameters to meet your
situation. (See "Sampling Setup" on page 134)
