things that remain the same for all of our plug-ins,
such as the menu row. ese will be explained in
this chapter. For detailed information of a particular
plug-in, please see its chapter.
Menu Row
In the bottom of the plug-in interface, you will see
a thin black row with some buttons. We’ll use the
Bass Amp Room plug-in as example, but the same
goes for all plug-ins.

When the Enable switch is set to  (I), the plug-

had many ideas for reimagining the historic console EQ to work in
a modern context. After experimenting with a number of prototypes,
Goeke incorporated several new features into the equalizer, creating
what is now considered a modern classic — the Chandler Limited
Curve Bender EQ.
Vintage Sound, Modern Features
at beast was called the Chandler Limited EMI TG12345 Curve
Bender, and it was issued in celebration of the 75th birthday of Abbey
Road Studios. Powerful functionality gives you serious sound shap-
ing mojo. Wade Goeke turned the nine xed frequency selections
of the original Abbey Road desk into 51 EQ points. He also added

8| CHANDLER LIMITED CURVE BENDER
the Multiply switch which increases the boost/cut
ability from 5 to 15 dB, as well as sharpening the Q.
He furthermore added high and low pass lters, and
bell/shelf selections on the high and low bands.
So the Chandler Limited EMI TG12345 Curve
Bender is a classic equalizer reimagined from the
glorious history of EMI and Abbey Road Studios
which has come full circle, morphing into a modern
powerhouse EQ perfect for all your recording, mix-
ing, and mastering needs.
The Curve Bender's additions to the original TG12345
feature set are marked with yellow text color on the
panel.The original features have white text color, except
the Mid/Side and Link features.

Output Gain Controls the output gain in
0.5 dB steps. Adjust this so
the output level is reasonably
matched to the unprocessed
sound of the original sound
source.is lets you accurately
perform A/B comparisons of
the Curve Bender bypassed
and active.
In Use
e Curve Bender alters the tonal content of the
sound source in a musical, yet transparent, manner.
It is equally useful during recording, mixing or mas-
its center position, the corre-
sponding band is bypassed.

tering. e most common use is probably on a ste-
reo source, with the unit in stereo mode and its left
and right channels linked. is means that exactly
the same processing is applied to both the left and
right side of the sound source. But it works equally
well on mono sources, and the ability to unlink the
left and right channels means you can apply dier-
ent equalization to the dierent sides, if necessary.
For example, a stereo recording might have been
made with slightly unmatched microphones—this
can be remedied by unlinking the Curve Bender’s
channels and apply equalization to match one side
to the other.
Mid/Side Tips
e Curve Bender plug-in oers a mode which is
not available on the hardware—the Mid/Side mode
(MS).
In Mid/Side mode, the Curve Bender will not pro-
cess the left and right channels separately. Instead,
the sound is separated into a  portion of the
sound, which contains only the material which is
common to both left and right channels (the mono
portion of the sound). e other portion is the 
portion of the sound, which contains only the mate-
rial which diers between left and right.
Mid/Side for Mastering
Mid/Side processing is typically useful in a master-
ing situation, where you are working on stereo
program material without access to the individual
channels. For example, the lead vocal is typically
placed rmly in the center of the stereo panorama
and thus entirely resides in the  portion of the
sound, and not at all in the  portion. So if you
nd a need to apply equalization to the lead vocal,
but wish to avoid aecting the other instruments in
the same frequency range, you can set Curve Bender
to / mode, and only adjust the  por-
tion to achieve the desired eect on the vocal. Do-
ing it this way leaves the  portion untouched—
where you in many cases will nd panned guitars
or stereo keyboards. You can of course also do the
opposite, only aect the  portion of the sound.
Stereo Widening
Mid/Side processing can also be used to make a
stereo sound appear wider. You do this by slightly
turning down the  portion of the sound—but
don’t go too far as you might end up with a center
“hole” in the mix.
Mono/Stereo Operation
e Curve Bender is a stereo unit, but can also be
used in  or -.
Please note, when using Curve Bender in  or
-, make sure the channels are linked
and Mid/Side Processing is disengaged.
