AT A GLANCE
N
eural DSP is no stranger
to delivering high quality
amp modelling, you just
need to check out its
stellar roster of plugins
to see that. So when the Helsinki-
based fi rm showed up to last
year’s NAMM with the Quad
Cortex fl oor modeller, you’ll
understand we got pretty excited
about it, in fact, the whole
guitar-playing world seemed to
get quite giddy over the prospect.
Not just because a revered
software company had released its
fi rst hardware product, but what
lay within its aluminium unibody.
From the off , the Quad Cortex
promises unrivaled power in such
a small footprint that Neural DSP
calls it “the most powerful fl oor
modeller on the planet”, stuff ed
with 2GHz of dedicated DSP power
straight out of its Quad-Core
SHARC processor.
All that power doesn’t mean
a thing if it can’t deliver sonically
and you can be rest assured that it
can, in spades. But that’s not all,
one of the biggest surprises on
using the Quad Cortex for the
fi rst time was how intuitive the
interface layout is. As soon as we’d
plugged in, we were instantly
surfi ng the huge number of
presets, cycling through and
adding various eff ects as if we’d
been using it for years. With the 7”
screen, there is plenty of screen
real estate to fi t the whole signal
chains, without the need for
diff erent menus dedicated to just
eff ects, or amp models, etc.
For live performance, there are
three main operation modes to the
Quad Cortex, you can select either
Preset, Stomp, or Scene. Preset
mode allows you to use the eight
stomp buttons to select one of
eight presets per Bank and with
the up and down stomp buttons
cycle through those Banks, with
a total of 32 available, meaning
you have 256 presets to play with
before you even need to start
creating your own. Scene mode
allows for eight snapshots of one
preset, so you can bypass eff ects
and tweak settings for eight
diff erent versions of the same
preset, which eff ectively gives you
over 2000 factory presets alone.
Stomp mode drills down into a
preset even further by allowing
you to assign individual eff ects,
amp models, Neural Captures and
IRs to one of the eight stomp
buttons. Once the individual
module is selected then the eight
stomp buttons can be used as
rotary encoders for settings
within that eff ect - genius!
The architecture for each preset
is fl exible as it comes and allows
you to experiment to your heart’s
content. The individual models
within a preset are laid out in a grid
and when building your own, you
can build up to four individual
signal routings with an amp
model, plus eff ects on each one,

STOMP+ROTARY
ACTUATORS
That’s ‘twisty stomp
buttons’ to you and
us! A crazy amount of
development has
gone into the whole
board, but the rotary
actuators feel like the
cherry on the cake.

INTERFACE
While all the
functions are
accessible via the
touchscreen, the
Quad Cortex also
excels at giving much
of this control over
to the footswitches
– perfect for gigging.
