Sampling (Open Sampling System)
Sampling overview
About sampling on the NAUTILUS
Overview
The NAUTILUS can sample external audio from the analog,
or USB inputs, at 48 kHz 16-bit resolution (or 24-bit when
sampling to disk), in mono or stereo. You can record
samples into RAM, or sample directly to disk.
You can also digitally resample the complete sound of a
Program, Combi, or Song, played live or sequenced,
including any effects and ARP-generated events.
Finally, you can process the inputs through the IFX, MFX,
and TFX, or through the synthesis functions of EXi such as
the MS-20EX and MOD-7.
You can combine any and all of these features at once. For
instance, you can sample a live guitar riff from the audio
inputs, processed through NAUTILUS effects, while
listening to and either recording or not recording a Drum
Track or Step Sequence phrase.
You can use your samples directly in Drum Kits, or make
them into Multisamples and use them anywhere that you use
ROM Multisamples, such as in HD-1 Programs or Wave
Sequences.
KSC Files and User Sample Banks
KSC stands for Korg Sample Collection. KSC files group
your Samples and Multisamples together, and let you load
them as User Sample Banks. User Sample Banks may be
loaded either into RAM, or may use Virtual Memory, just
like EXs. They have other benefits as well. For more
information, see "Creating and saving .KSC files" on
page 180.
Sampling and RAM
The NAUTILUS comes with 3 GB of RAM pre-installed.
Approximately 1 GB of this RAM is used by the operating
system and ROM sample data. The remainder is shared
between the samples in EXs, User Sample Banks, and
SAMPLING mode.
This means that the size of the currently loaded EXs and
User Sample Banks trades off against the memory available
for SAMPLING mode. The more space used by EXs and
User Sample Banks, the less is available for SAMPLING
mode.
Using Virtual Memory for EXs and User Sample Banks
generally lets you load more samples at once, but may still
use a substantial amount of RAM.
Note: To check the amount of sample RAM available, see
"0–1f: Free Sample Memory/Locations" on page 579 of the
PG.
The amount of sampling time depends on the amount of free
RAM, as shown below.

Sampling to drive
You can sample directly to drive (including the internal drive
and USB storage devices), creating a WAVE file. This lets
you record up to 80 minutes continuously, in either mono or
stereo (mono: approximately 440 MB, stereo: approximately
879 MB).
As long as they fit into the available RAM, these WAVE
files can then be loaded into SAMPLING mode and used in
Drum Kits, HD-1 Programs or Wave Sequences. (Note that
after loading them into SAMPLING mode, you'll need to
save them again; the WAVE files can't be used directly for
Programs, etc.)
WAVE files can also be used in audio tracks of the
sequencer. For more information, see "Audio recording" on
page 91.
24-bit sampling to drive
When sampling to drive, you can choose either 16-bit or 24-
bit resolution. Both 16- and 24-bit WAVE files can be used
directly in SEQUENCER mode audio tracks. When loaded
as RAM samples, 24-bit WAVE files are automatically
converted to 16-bit resolution.
Sampling in SAMPLING mode
In SAMPLING mode, you can sample analog audio from
connected microphones or line inputs, or digital audio from
USB. If you like, you can also sample through the
NAUTILUS effects.
Samples can be processed through effects and internally
sampled again ("resampled"). You can use either "Auto"
mode which automatically applies the specified effect
processing to the selected sample, or "Manual" mode which
lets you play the sample manually with effects applied and
resample your performance.
