Sampling (Open Sampling System)
Sampling Overview
About sampling
The M3 features Korg’s Open Sampling System, which
allows you to perform sampling and resampling not
only in Sampling mode, but also in Program,
Combination, and Sequencer modes with functionality
that is optimized for each different mode.
• Audio signals from an external source connected to
the AUDIO INPUT jacks or S/P DIF IN jacks will
be sampled in stereo, with 48 kHz/16-bit
resolution. Analog signals will be converted into
digital data when they are sampled. Digital signals
will remain in the digital domain as they are
sampled.
Note: If the optional EXB-FW is installed, you’ll be able
to input digital signals from M3 Plug-In Editor
running in your host application. For details, refer to
the “M3 Editor/Plug-In Editor Manual” (PDF).
• Performances using the M3’s filters, effects,
KARMA function, and sequencer can be resampled.
• Audio signals from an audio CD can be extracted
(ripped) directly in the digital domain.
These sampling/resampling operations can be
performed into the M3’s RAM memory or into a USB
storage device (such as a commercially available hard
disk) connected to the USB A connector.
Sampling to RAM memory or a USB
storage device
Sampling to RAM memory
If you want to use the sampled/resampled
multisample or sample as a sound generator waveform
in an EDS program or a drum kit, you should sample
to RAM memory.
The M3 comes with 64 Mbytes of RAM built in, and
you can install a optional EXB-M256 to add an addition
256 Mbytes. Of the 64 Mbytes of RAM, 512 bytes are
used by the system, and will not be available for
sampling.
The amount of sampling time depends on the amount
of free RAM, as shown below:
Free RAM and approximate sampling times
The multisample and sample data in the RAM
memory is not backed up when the power is
turned off. If you wish to keep this data, you must
save it onto a media before turning off the power.
When the power is first turned on, memory will
not contain any multisample or sample data. You
must first load previously-saved data before you
can playback or edit any sample data.
Installing the optional EXB-M256
The EXB-M256 is a memory board with 256 MB
(megabytes) of capacity.
In Sampling mode, you’ll be able to select sample
memory bank RAM2. Refer to the above table for the
sampling times when using bank RAM2.
In addition, you’ll be able to load sample files of
various formats (KORG, WAVE, AIFF, AKAI (S1000/
S3000), SoundFont 2.0), or load optional PCM
expansion USB memory data.
For details on how to install the EXB-M256, please see
“Specifications and options” on page 224.
Sampling to a USB storage device
If you sample/resample to a USB storage device (such
as a commercially available hard disk) connected to the
M3’s USB A connector, the sample will be saved as a
WAVE file.
You can load this sample (WAVE file) into the M3’s
RAM memory and use it as a sound generator
waveform. Alternatively, if you’ve resampled a song
you created on the sequencer, you can use the resulting
WAVE file to create an audio CD by using a USB CD-
R/RW drive (commercially available). Since this data
is an ordinary WAVE file, you can also load it into your
computer and use it for any purpose.
One sample file allows a maximum of 80 minutes
(mono: approximately 440 Mbytes, stereo:
approximately 879 Mbytes) of user sampling, whether
mono or stereo.
Sampling/resampling functionality in
each mode
Sampling mode
1. Analog audio signals from a mic or audio device
connected to the AUDIO INPUT jacks can be
converted into digital signals and sampled.
You can also apply effects while sampling.
2. Digital audio signal from a digital audio device
connected to the S/P DIF jack can be sampled
directly.
You can also apply effects while sampling. The S/
P DIF input/output jacks support sample rates of
48 kHz.
Note: If the optional EXB-FW is installed, you can also
sample from the FireWire connector.
