Introduction
About dspMixFx UR-C
This software is for operating the convenient built-in DSP mixer and DSP effects in UR-C/URX-C series devices.
dspMixFx allows you to mix input signals down to one stereo output.
A number of DSP effects for processing the input signals are provided.
Since the processing/mixing is hardware-based, there is no monitoring latency.
Connecting to an iOS Device (UR44C/URX44C/UR816C only)
You can use an iOS device to operate the built-in DSP mixer and DSP effects via Wi-Fi.
dspMixFx Remote Bridge must be installed on the Windows/Mac machine to which the iOS device is tethered via
Wi-Fi.
For details, refer to the “dspMixFx Remote Bridge User’s Guide.”

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.
Six 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.
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).
For more information about the VST Plug-in version, refer to the “Basic FX Suite Operation Manual.”

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

preset file. 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 equipped with the device cannot be used when the sample rate is set to 176.4 kHz or 192 kHz.
For more information about the VST Plug-in version, refer to the “Basic FX Suite Operation Manual.”

Guitar Amp Classics Reference
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.

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. 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).
For more information about the VST Plug-in version, refer to the “Basic FX Suite Operation Manual.”
The built-in REV-X is equipped with an “FX Bus” that is used for sending the signal from DAW software to REV-X
(UR44C/URX44C/UR816C only). To send the recorded audio data to REV-X, you can check the sound with REV-X,
which is used for monitoring while recording.
