Using the G1u as an Audio Interface

When the G1u is connected to a computer via
the USB port, it can function as an audio
interface for the computer. The operating
environment conditions for this type of use are
as follows.
n Compatible operating systems
• Windows XP SP2 or later
Windows Vista or later
• MacOS X (version 10.4.6 or later/10.5
or later
n Quantization
16-bit
n Sampling frequencies
32 kHz / 44.1 kHz / 48 kHz
With the operating systems listed above, the G1u
will function as an audio interface simply by
connecting the USB cable. There is no need to
install any special driver software.
However, the supplied dedicated ASIO driver
allows low-latency audio recording and playback.
If the G1u is connected to a computer via
HINT
a USB cable, and the AC adapter is not
connected, power will be supplied via the
USB port.
In this condition, the sound of a guitar connected
to the [INPUT] jack of the G1u can be processed
with the effects of the G1u and then be recorded
on the audio tracks of a DAW (Digital Audio
Workstation) software application running on the
computer.

At the same time, the [OUTPUT] jack of the G1u
carries the playback sound from the audio tracks
of the DAW application, mixed with the guitar
sound processed by the effects of the G1u.
For details on recording and playback steps, refer
to the documentation of the DAW application.

processing is always available directly
at the [OUTPUT] jack (allowing use of
the unit as an effect).
· If the DAW application has an echo
back function (input signal during
recording is supplied directly to an
output), this must be disabled when
using the G1u. If recording is carried
out with this function enabled, the
output signal will sound as if processed
by a flanger effect.
· Use a high-quality USB cable and keep
the connection as short as possible. If
power is supplied to the G1u via a USB
cable that is more than 3 meters in

Effect Types and Parameters

Explanation of symbols

• Module selector
Shows the position of the knob at which
this module/parameter is called up.
• Expression pedal
Indicates
a parameter that can be
controlled with the expression pedal.
* Manufacturer names and product names mentioned in this listing are trademarks or
registered trademarks of their respective owners. The names are used only to illustrate
sonic characteristics after which the effects are modeled and do not indicate any affiliation
with ZOOM CORPORATION.
For some effect modules, you can select an effect type from several possible choices.
n PATCH LEVEL
PATCH LEVEL (Prm)
Sets the overall volume level of the patch.
The setting range is 2 – 98, and 1.0. A setting of 80 corresponds to unity gain (input level and output level
2 1 0
are equal).
n COMP/EFX (Compressor/Special Effects) module
COMP/EFX (Type&Prm)
Selects the COMP/EFX module effect type and parameter.
Compressor
C 1 C 9
This is an MXR Dynacomp type compressor which limits high-level signals and boosts low-level signals to
compress the overall dynamics of the signal. Higher settings result in higher sensitivity.
Auto Wah
A 1 A 9
This effect varies wah in accordance with picking intensity. Higher settings result in higher sensitivity.
Booster
B 1 B 9
Raises signal gain and creates a dynamic sound. Higher settings result in higher gain.
Tremolo
T 1 T 9
This effect periodically varies the volume. Higher settings result in faster modulation rate.
RingMod (Ring Modulator)
R 1 R 9
This effect produces a metallic ringing sound. Higher settings result in higher modulation frequency.
Slow Attack
S 1 S 9
This effect reduces the attack rate of each individual note. Higher settings result in slower attack times.

Effect Types and Parameters
• Tap
Indicates a parameter that can be set by
repeatedly tapping the [BANK UP·TAP]
key. When the module/effect type is
selected in edit mode, the parameter
(modulation rate or delay time, etc.) will be
set according to the interval in which the
key is pressed.
