Setup
This chapter explains how to start up the stand-alone application after installation, and
how to make preference settings so you can use it.

Starting up Stand-alone application

1 Use a USB cable to connect the external MIDI device to your computer.

2 Navigate to the “KORG” folder - the software synthesizer folder, and double-click
the software synthesizer icon to start up the program.

Windows
The software synthesizer folder is in the location you specified when installing the
software. By default, it will be in the “KORG” folder within the “Program Files”
folder. Alternatively, you can click the [Start] button on the task bar, then “All Pro-
grams,” and start up the program by choosing from “KORG ” folder - the software
synthesizer folder.

Mac
Navigate to the “Application” folder - “KORG” folder - the software synthesizer
folder, and double-click software synthesizer icon to startup the program.

3 From the System menu, choose “Preference.”

The first time you start up the software, or if the preference settings have been
cleared for some reason, or if your computer system has changed, the preference
dialog box will appear automatically at start-up.

Audio settings

1 In “Driver type” or “Output Device,” select the type of audio driver you want to
use.

Windows
ASIO: The ASIO driver will be used. ASIO drivers allow minimal latency, and will
give you the best performance. If an ASIO driver is installed, we recommend that
you use this setting.
DirectSound: DirectSound will be used. Use this setting if an ASIO driver is not
installed in your computer.
MME: MME (Multi Media Extension) will be used.

Since MME has higher latency than other settings, we recommend that you use
another setting if possible.

Mac
If audio interface is installed in your computer, you will be able to select the driver
for that audio interface.

2
 Setup

If audio interface is not installed, you will only be able to select “ Built-in audio
controller.”

2 Specify the audio output.

Windows
• If you selected ASIO in “Driver type”
This will be unavailable and cannot be selected if an ASIO driver is not installed in
your computer.

“Driver”
Select the driver (device) you will use.
“Sampling Rate”
Select the sampling rate you will use. The choices for “Sampling rate” will depend
on the device you select for “Driver.”
“Out Channel”
Select the output channels. This setting will always be a pair such as 1-2 or 3-4. The
choices will depend on the device you select for “Driver.”

Only for the software synthesizer with audio inputs, “Input Channels” will appear
in the screen, allowing you to specify audio channels for input. This will always be
a pair of channels, such as 1–2 or 3–4. The available settings will depend on the
device you selected for “Driver.”

“Clock Source”
Select the audio clock source that you will use. The choices will depend on the
device you select for “Driver.”
“ASIO Control Panel”
Click this to open the ASIO driver settings panel.
The contents and operation in this panel will depend on the driver you are using.
For details, refer to the owner’s manual for your audio interface.
• If you select DirectSound or MME as the “Driver type”
“In Driver”
Select the driver (device) you will use.

In some cases, the same driver may appear more than once. Select one of them.

“Bit/Smpl Rate/Ch”
Select the audio format you will use. The choices will depend on the device you
select for “Input driver.”
“Buffer Size”
Specify the number of audio processing buffers. Higher settings will make opera-
tion more stable, but latency will be higher. Latency is the time from when the
computer receives a note-on message until sound is produced. Latency is deter-
mined by “the number of samples” x “the number of buffers.” You should set the
buffer size and the sample size in a way that minimizes latency while preserving
stable operation.

 Installation /Setup guide

“Sample Size”
Specify the number of samples in one buffer. Higher settings will make operation
more stable, but latency will be higher.

Mac
“Bits/Rate/Channel”
Select the audio format you will use. The choices will depend on the device you
selected as the “Output Device.”

Only for the software synthesizer with audio inputs, “Input Channels” will appear
in the screen, allowing you to specify audio channels for input. This will always be
a pair of channels, such as 1–2 or 3–4. The available settings will depend on the
device you selected for “Driver.”

“Output Channel”
If you selected “Built-in audio controller” as the “Output Device,” the only avail-
able setting will be Output 1/Output 2. If audio interface is installed in your com-
puter, you will have other choices.
“Buffer Size”
Specify the size of the audio processing buffer. Higher settings will make opera-
tion more stable, but latency will be higher.
“Latency”
This indicates the latency. The latency will depend on the “Buffer Size” setting.
Latency is the time from when the computer receives a note-on message until
sound is produced. Latency is determined by “the number of samples” x “the
number of buffers.” You should set the buffer size in a way that minimizes latency
while preserving stable operation.

The “Latency” value is determined by the buffer size. You should set “Buffer Size”
to the lowest setting for which operation is stable.

For details on how to make settings for your audio interface, refer to the owner’s
manual for your audio interface.

MIDI settings

1 Click the “MIDI Setting” tab.

2 For MIDI IN devices 1, 2, and 3, select the device that you will use for each port.
You can use up to three MIDI IN devices simultaneously. Normally, the input
from these devices will all be merged. If a multi-port device is connected, this
screen may show two or more ports on the same device.

3 In the “Clock Master” field, select the device that will be the MIDI clock master.
If you don’t select a device, the internal clock will always be used. When the soft-
ware instrument is operating as a plug-in, the clock of the host application will
always be used.

 Setup

If the device you want to use does not appear in the selection for each port, check
the following points.

Win: Is the connected device driver installed?

Mac:Is the connected device detected in your computer?

Mac:If the device you want to use does not appear in the selection for each port, navi-
gate to the Application folder ➝ Utility ➝ “Audio MIDI Setup,” display the
“MIDI device” tab page, and check whether the connected external MIDI device
has been detected.

Other settings

1 Click the “Other” tab.

2 In the Control area, set “Knob Mode” to specify how you want the knobs to oper-
ate.
Circular
Edit values by moving the mouse pointer to the mark indicating a knob’s value,
and dragging to turn the knob. You can also move the knob immediately by
directly clicking the desired position.
Relative Circular
Edit values by dragging as if to turn the knob to the desired position. You will not
be able to move the knob by clicking as with the “Circular” setting above.
Linear
Edit values by dragging the knob upward or downward.

3 In the AutoStop Setting area, specify if and when you want the audio to stop auto-
matically.
The Auto Stop function automatically stops the audio depending on the CPU load
of your computer. (The result is the same as when you execute the “System” menu
command “Stop Audio.”) If you want to use the Auto Stop function, check the
“Enable AutoStop” check box, and use the “AutoStop Rate” slider to specify the
load threshold at which the audio will be stopped. If the CPU load exceeds this
threshold during operation, the audio will stop. If the audio has been stopped
automatically, use the “System” menu command “Play audio” to resume playing.

If audio stops frequently, try lightening the load on the CPU by reducing the
polyphony of the synthesizer(s).

If you don’t use the Auto Stop function, the system will attempt to continue pro-
ducing audio as long as possible. However, depending on the hardware you are
using, you may experience problems such as the mouse becoming unresponsive
when the audio load is high.

4 Click “OK” to finalize the preference settings.
