dspMixFx UR-RT
This software is for operating the convenient built-in DSP
mixer and DSP effects. The DSP mixer allows you to mix
up to six input channels {four input channels} down to one
stereo output. A number of DSP effects for processing the
input signals are also provided, and since the processing/
mixing is hardware-based, there is no monitoring latency.
NOTE
You cannot operate dspMixFx UR-RT while a Cubase series DAW is
running. When Cubase is running, configure the DSP mixer and
DSP effect from “Dedicated Windows for Cubase Series” (page 16).

What is Loopback?
Loopback is a convenient function for broadcasting over
the Internet. It mixes the input audio signals (such as
microphone and guitar) with the audio signals playing
back in the software in the computer into two channels in
the UR-RT, and sends them back to the computer. Refer to
the section “Signal Flow” (page 37).
If the Loopback function is on while you are monitoring
input signals from the UR-RT via DAW software, it will
cause loud noise. This is because an infinite loop of the
audio signal is generated between the UR-RT and the
DAW software. When using the loopback function, turn off
the monitor functions on your DAW software.

Sweet Spot Morphing Channel
Strip
The Sweet Spot Morphing Channel Strip (“Channel Strip”
for short) is a multi-effect that combines compression and
EQ. Advanced sound engineering know-how is
condensed into a number of convenient presets that can
be simply and instantly recalled, for professional results.
Four channel strips are provided, and each can be
assigned to the monitor sound only, or to both the monitor
and recorded sound.
The Channel Strip equipped with the device and the
Channel Strip of the VST Plug-in version have the same
parameters. When using the Channel Strip on Cubase
series programs, you can share the settings between the
built-in Channel Strip and the Channel Strip of the VST
Plug-in version as a preset file. When using the built-in
Channel Strip on Cubase series programs, turn on the
[Direct Monitoring] setting in the program. Also, when
assigning the Channel Strip of the VST Plug-in version to
the effect slot on Cubase series programs, select it from
the [Dynamics] category (in the case of the default
settings). Note that you cannot use the built-in Channel
Strip when the sample rate is set to 176.4 kHz or 192 kHz.

REV-X
REV-X is a digital reverb platform developed by Yamaha
for pro audio applications.
One REV-X effect is included in this unit. Input signals can
be sent to the REV-X effect, and the REV-X effect is
applied only to the monitor outputs. Three types of REV-X
are available: Hall, Room, and Plate. The hardware REV-X
equipped with the device and REV-X of the VST Plug-in
version have essentially the same parameters. However,
the [OUTPUT] and [MIX] parameters are only available in
the VST Plug-in version.
When using REV-X on Cubase series programs, you can
share the settings between the built-in REV-X and REV-X
of the VST Plug-in version as a preset file. When using the
built-in REV-X on Cubase series programs, turn on the
[Direct Monitoring] setting in the program. Also, when
assigning REV-X of the VST Plug-in version to the effect
slot on Cubase series programs, select it from the
[Reverb] category (in the case of the default settings).
The built-in REV-X is equipped with an “FX Bus” which is
used for sending the signal from DAW software to REV-X.
For example, to send the recorded audio data to REV-X,
you can check the sound with REV-X, which is used for
monitoring during the recording.

Guitar Amp Classics
Guitar Amp Classics are guitar amp simulations that make
extensive use of advanced Yamaha modeling technology.
Four amp types with different sonic characteristics are
provided.
The Guitar Amp Classics equipped with the device and
the Guitar Amp Classics of the VST Plug-in version have
the same parameters. When using the Guitar Amp
Classics on Cubase series programs, you can share the
settings between the built-in Guitar Amp Classics and the
Guitar Amp Classics of the VST Plug-in version as a
preset file.
When using the built-in Guitar Amp Classics on Cubase
series programs, turn on the [Direct Monitoring] setting in
the program. Also, when assigning the Guitar Amp
Classics of the VST Plug-in version to the effect slot on
Cubase series programs, select it from the [Distortion]
category (in the case of the default settings).
Note that Guitar Amp Classics cannot be used when the
sample rate is set to 176.4 kHz or 192 kHz.

Select the “Guitar Amp Classics” from the “Effect Type”,
then click “Effect Edit” in the section “Channel Area”

CLEAN
This amp type is optimized for clean tones, effectively
simulating the tight brilliance of transistor amplifiers. The
tonal character of this amp model provides an ideal
platform for recording with multi-effects. It also features
built-in chorus and vibrato effects.
1 VOLUME
Adjusts the amplifier’s input level.

4 PRESENCE
Can be adjusted to emphasize the high frequencies and
overtones.
5 Cho/OFF/Vib
Turns the Chorus or Vibrato effect on or off. Set to [Cho] to
turn the Chorus effect on, or to [Vib] to turn the Vibrato
effect on.
6 SPEED/DEPTH
These controls adjust the speed and depth of the Vibrato
effect when it is on. The SPEED and DEPTH controls only
work with the Vibrato effect, and are disengaged when the
Cho/OFF/Vib control, above, is set to “Cho” or “OFF.
7 BLEND

CRUNCH
This is the amp type to use when you want lightly
overdriven crunch tones. The CRUNCH model simulates
the type of vintage tube amplifiers that are favored for
blues, rock, soul, R&B, and similar styles.
1 Normal/Bright
Selects a normal or bright tonal character.
The [Bright] setting emphasizes the high-frequency
overtones.
2 GAIN
Adjusts the input level applied to the preamp stage.
Rotate clockwise to increase the amount of overdrive
produced.
3 TREBLE/MIDDLE/BASS
These three controls adjust the amplifier’s tonal response
in the high, middle, and low frequency ranges.
1 AMP TYPE
Six amplifier types are provided. Types 1 and 2 feature
relatively mild distortion that allows picking nuances to
come through naturally. Types 3 and 4 have more
pronounced overtones, resulting in a fat, soft tone. Types
5 and 6 deliver wilder, aggressive distortion with a tight
attack. The even-numbered amp types have greater
presence and range than the odd-numbered types.
2 GAIN
Adjusts the input level applied to the preamp stage.
Rotate clockwise to increase the amount of distortion
produced
3 MASTER
Adjusts the output level from the preamp stage.
4 TREBLE/MIDDLE/BASS
These three controls adjust the amplifier’s tonal response
in the high, middle, and low frequency ranges.
5 PRESENCE
Can be adjusted to emphasize the high frequencies and
overtones.
6 OUTPUT
Adjusts the final output level
4 PRESENCE
Can be adjusted to emphasize the high frequencies and
overtones.
5 OUTPUT
Adjusts the final output level.
DRIVE
The DRIVE amp type provides a selection of distortion
sounds that simulate the tonal character of various
highgain tube amplifiers. From mildly overdriven crunch to
heavy distortion suitable for hard rock, heavy metal, or
hardcore styles, this model offers a wide range of sonic
capabilities.
LEAD
The LEAD amp type simulates a high-gain tube amp that
is rich in overtones. It is ideally suited to playing lead
guitar lines that will project well in an ensemble, but it can
also be set up for crisp accompaniment tones as well.
1 High/Low
Selects the amp output type.
The [High] setting simulates a high-output amp, and
allows the creation of more distorted tones.
2 GAIN
Adjusts the input level applied to the preamp stage.
Rotate clockwise to increase the amount of distortion
produced.
3 MASTER
Adjusts the output level from the preamp stage.
4 TREBLE/MIDDLE/BASS
These three controls adjust the amplifier’s tonal response
in the high, middle, and low frequency ranges.
UR-RT4 / UR-RT2 Operation Manual24
5 PRESENCE
Used to emphasize the high frequencies and overtones.
6 OUTPUT
Adjusts the final output level.
Using the GAIN, MASTER, and OUTPUT Controls
The tonal character of the DRIVE and LEAD amp types can
be adjusted over a wide range via the GAIN, MASTER, and
OUTPUT controls. GAIN adjusts the level of the signal
applied to the preamp stage, affecting the amount of
distortion produced. MASTER adjusts the output level from
the preamp stage that is then fed to power amp stage. The
GAIN and MASTER control settings have a large effect on
the final sound, and the MASTER control may need to be
turned up fairly high in order to drive the power stage
sufficiently for optimum tone. The OUTPUT control adjusts
the final output level from the amp model without affecting
the distortion or tone, and is useful for adjusting the guitar’s
volume without changing any other aspects of the sound.
