Chaining FX - FX devices can be routed to each other. For
example you could patch the output of a Delay unit into a
Reverb, and then return the reverb to the main mix.
View Outputs – Touch the View Outputs button to open a
window showing where the outputs of the FX device are
routed. Each slot can handle up to 8 outputs depending on
the device loaded. Most provide 2 outputs (stereo).
Unassign – Touch this button to reset the FX device
outputs to feed its related short FX Return channel.
5.3 FX Libraries
Touch the Library button to open the Library window. Touch
the Exit Library button to close the window.
The Libraries are grouped according to FX type. You can
choose to load one of many 'Factory' presets from the
menus, or to recall a previously stored 'User' preset from
the memory or directly from your USB key.
Factory, User/USB – Touch to show the available Factory
presets or to show the User presets currently stored in GLD
memory and those found on a USB key plugged in.
Recall – Scroll through the list and touch to select a preset.
Touch Recall to load the highlighted preset.
Store New – Touch to store the current FX settings as a
User preset. Name the preset using the touch keypad.
Overwrite - To update an existing User preset first select it
in the list then touch the Overwrite button. Factory presets
cannot be overwritten or deleted.
User Libraries can be deleted or transferred to or from your
USB key using the Setup / Memory / Library Manager
page.
Note You do not need to use up FX slots to attach Graphic
Equalisers to the mixes. Each of the 20 mix outputs has a
GEQ available within its processing screen.

SMR Reverb
SMR Live is a Spatial Modelling Reverberator featuring 4
fully configurable complex spatial models Classic, Hall,
Room and EMT. Each of these models use different
reflection and decay algorithms to provide natural sound
spaces ideal for Live sound.
Classic Emulates high quality plates. Shape tailors the
reflection pattern. Min position for fast attack, mid position
for rounded early reflections, and max position for
separated early and late reflection patterns. Adjusting
shape/size/predelay with decay can result in some great
Hall reverbs. Small size settings not very useful in live
sound applications.
Hall Emulates a real Hall reflection model. No shape
control, reflections are controlled with Size, Source diffusion
and Ref detail with rich deep decay spectrum.
Room Accurately emulates a characteristic complex room
reflection pattern.
EMT Classic plate emulation. A great plate with good tonal
balance for live use. Decay setting around 2 seconds is
typical.
The SMR primary controls essential for live mixing are
always visible:
LF Cut - 0 to 400Hz, 24dB/octave high pass filter to cut low
frequencies of the input signal to the reverb.
HF Cut - 2kHz to 20kHz, 24dB/octave low pass filter to cut
high frequencies of the input signal to the reverb.
Predelay - The time it takes before the reverb reflections
and decay are heard.
Decay Time - Broad spectrum decay control. The time it
takes for the reflections to decay to 60dB below the level of
the direct sound is known as the RT60, an important
measurement of reverb in a room.
HF Decay - Frequency at which the high frequency decay
attenuation starts.
HF Slope - The attenuation slope of the high frequency
decay. HF Decay and Slope are both essential for high
frequency decay spectrum adjustment in a live space.
Setting HF Decay and Slope low creates a natural sounding
decay. Setting HF Decay and Slope high creates a dramatic
decay.
