Sampling mode
Sampling Overview
The OASYS can sample external audio from the analog 
or S/P DIF inputs, at 48 kHz 16-bit resolution, 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 KARMA-generated events.
Finally, you can also sample (or “rip”) directly from an 
audio CD, in the digital domain.
Once a sample is loaded into RAM, you can use it 
directly in Drum Kits, or make it into a Multisample 
and use it anywhere that you use ROM Multisamples, 
such as in HD-1 Programs or Wave Sequences.
Sampling to RAM, or direct to disk
Sampling and RAM
The OASYS comes with 1 GB of RAM pre-installed, 
which can be expanded up to 2 GB with a user-
installable DIMM module. This memory is shared 
between the operating system, ROM and EXs samples, 
and RAM samples.
In particular, the size of the currently loaded EXs 
samples trades off against the memory available for 
RAM samples. The more space used by the EXs 
samples, the less is available for RAM samples.
You can choose which EXs are loaded, if any, by using 
the Expansion Sample Setup menu command, on the 
Global mode Basic Setup page. For more information, 
see “Expansion Sample Setup” on page 684.
EXs samples and available sample RAM
Note: To check the amount of sample RAM available, 
see “0–1f: Free Sample Memory/Locations” on 
page 572.
The amount of sampling time depends on the amount 
of free RAM, as shown below:
Installing additional RAM
You can install additional RAM, up to a total of 2 GB. 
For more information, see “Installing memory” on 
page 1038.
Sampling to disk
You can sample directly to disk, 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 RAM and used in Drum 
Kits, HD-1 Programs or Wave Sequences. 
WAVE files can also be used in audio tracks of the 
sequencer, or used to create an audio CD. For more 
information, see the Operation Guide under “Audio 
recording” on page 96, and “Creating and playing 
audio CDs” on page 175.
Sampling features
Sampling on the OASYS
The OASYS features Korg’s Open Sampling System. 
This lets you use sampling and resampling not only in 
Sampling mode but also in Program, Combination, 
and Sequencer modes, with optimized features for 
each mode.
• You can perform 48 kHz 16-bit linear mono or 
stereo sampling.
• A maximum of 1,000 multisamples and 4,000 
samples can be created.
• In Disk mode, you can load multisample/sample 
data from various types of media.
• You can load several different formats of sample 
data, including Korg’s own format, Akai 
S1000/3000 samples and program data, and AIFF 
or WAVE samples. (Once data has been loaded into 
the OASYS, it will all be treated as Korg format 
sample data.)
• You can export samples created on the OASYS as 
AIFF or WAVE files.
• You can use all of the Insert, Master, and Total 
effects to process signals before sampling, from
