Audio interface manual
Audio interface and control surface
Functions of the audio interface and control surface
This section explains how to connect the unit with a computer and how to set up and
use the audio interface and control surface functions of the R24 with a DAW and other
software.
Control surface functions
On-board control surface functions can be
used to control DAW software on a com-
puter via USB. Transport operations, in-
cluding playback, recording and stopping,
and physical control of the DAW faders
are possible. Furthermore, various other
DAW software functions can be mapped
to the F1~F5 keys (assignable functions
depend on the DAW used).

Audio interface
The R24 has numerous inputs and outputs
and it can be used as a Hi-Speed USB
(USB 2.0) audio interface with 8 inputs
and 2 outputs at quality up to 24-bit/96
kHz. Effects can be used when the sam-
pling rate is 44.1 kHz, and the unit can be
powered by a computer’s USB bus.

4
Audio interface manual
Multifunction tuner
In addition to standard chromatic tuning,
the on-board multifunction tuner also sup-
ports 7-string guitar, 5-string bass and
various drop tunings.
Comprehensive built-in mixer
Using the R24’s mixer, you can make a
mix for monitoring. When simultaneously
recording guitar and vocals, for example,
you can adjust volume balance, panning
and reverb levels.
Moreover, you can also adjust the balance
between the built-in mixer and the sound
sent from a computer.
Versatile effect functions
Built-in insert effects can be applied to
specific channel paths, and two-types
of send/return effects work via the mixer
send/return. These effects can be applied
when recording, of course, but they can
also be applied to only the monitor output.
For example, when recording vocals, you
can apply reverb only to the monitor sig-
nal to make singing easier.
Supports input from a variety of
sources, including guitars, mics and
line level instruments
The 8 onboard jacks accept XLR and
standard phone plugs and include one
high-impedance input and two inputs with
phantom power (24V or 48V).
Many sources are supported from high-
impedance guitars and basses to dynamic
and condenser microphones and line-
level devices like synthesizers. In addition,
built-in high- performance condenser
microphones are convenient for recording
acoustic guitars and vocals.

Cubase LE 5 installation overview
By using the R24 between a computer and
external audio devices and instruments, their
signals can be recorded using a DAW or other
software. Instruments and mics that require
Hi-Z or phantom power can also be connected.
Using the faders and keys on the R24, you can
control transport operation and mixing in digi-
tal audio workstation (DAW) software on your
computer.
To use the R24 with DAW software, after installing that software, a driver must be
installed and set to recognize it. We explain how to do this with Cubase LE 5.

Fader section operation
Using the faders and status keys of the fader section, you can adjust the volume of
corresponding Cubase LE 5 tracks, mute and solo them, and arm them for recording.
Operating the fader section
1Assign the Cubase LE 5 tracks
(channels) that you want to control
to the fader section.
About banks
After setting up control surface operation, the
main parameters of Cubase LE 5 can be oper-
ated using the R24’s fader and status keys.
A group of tracks operated by the faders and
status keys is called a “bank.” With the R24,
one bank of 8 adjacent tracks can be con-
trolled.
For example, if fader 1 is assigned to Cubase
LE 5 track 1, tracks 1-8 can be controlled as
shown in the following diagram.
Control 1 2 3 4 5 6 7 8
Track Tr.1 Tr.2 Tr.3 Tr.4 Tr.5 Tr.6 Tr.7 Tr.8
As the diagram shows, when tracks 1~8 are
selected, pressing the [9~16tr (Bank>)] key
once switches the assignments as shown be-
low.

NOTE
• If the Monitor button is on, the R24 input signal
and the signal returning to the R24 via the
computer will both be output from the R24 at
the same time. This can create a flanger-like
sound. To monitor accurately while adjusting the
recording level, turn the BALANCE knob toward
DIRECT.
• The meter above shows the signal level after it
has been processed internally by Cubase LE 5.
For this reason, a slight delay might occur from
the time a string is plucked until the level meter
moves; this is not a defect.
Adjust the recording level
9While playing the instrument,
adjust the R24 input level and set
the Cubase LE 5 recording level.
The recording level for Cubase LE 5 can be
checked by viewing the level meter of the
corresponding channel of the recording-enabled
track. Please set it as high as possible without
making the meter peak.
When adjusting the level, do not move the Cubase
LE 5 fader, but instead use the fader and adjust
the gain on the R16.

Tips to improve performance
When using Cubase LE 5, application perfor-
mance could become extremely delayed or
error messages such as “cannot synchronize
with USB audio interface” might be dis-
played. Should such occurrences become
frequent, the following measures might im-
prove the situation.
➊ Terminate programs other than
Cubase LE 5 that are running.
In particular, confirm that many background
applications are not running.
➋ Reduce the use of plug-ins
(effects, virtual instruments)
If a large number of plug-ins are running, the
computer processing capacity might not be
able to keep up. In addition, reducing the
number of simultaneous playback tracks
might be effective.
➌ Use the R24 AC adapter
When devices draw power from the USB
bus, on rare occasions computer perfor-
mance can suffer. Try using the AC adapter.
If the sound breaks up, please increase the
Audio Buffer Size in the Device Setup…
menu > VST Audio System window.
For details, see Step 5 of the Cubase LE 5
Startup Guide.
Moreover, if the application performance is
extremely slow and regular computer op-
eration is affected, we recommend quitting
Cubase LE 5 and disconnecting the R24
USB port from the computer once, and then
reconnecting the USB port and relaunching
Cubase LE 5.
Check the recording (playback)
HINT
If no sound comes out after clicking the Play button
following recording, recheck the VST Connections
(step 6 in the Cubase LE 5 Startup Guide).
In addition, conrm that the BALANCE control is at
the center.
4Raise the master channel fader to a
suitable playback level.

Importing audio data into Cubase LE 5
By connecting a computer and the R24 with a USB cable and setting the R24 to

For optimum enjoyment
While using Cubase LE 5, other applications may slow down drastically
or a message such as “Cannot synchronize with USB audio interface”
may appear. If this happens frequently, consider taking the following
steps to optimize the operation conditions for Cubase LE 5.
1) Shut down other applications besides Cubase LE 5.
In particular, check for resident software and other utilities.
2) Reduce plug-ins (effects, instruments) used
by Cubase LE 5.
When there is a high number of plug-ins, the computer's processing
power may not be able to keep up. Reducing the number of tracks for
simultaneous playback can also be helpful.
3) Power the R24 from an AC adapter.
When a device designed to use USB power is powered via the USB
port, the current supply may sometimes fluctuate, leading to problems.
See if using an AC adapter improves operation.
Please set latency from the device menu when the sound
cutting occurs. Refer: Install Guide-step5 about details.
If applications still run very slowly or the computer itself does
not function properly, disconnect the R24 from the computer
and shut down Cubase LE 5. Then reconnect the USB cable
and start Cubase LE 5 again.
