3. Introduction
Hi – and thank you for purchasing Duende – the SSL processing solution for your audio
workstation. As you’re sat here reading this, the chances are that you have a pretty good
understanding of who we are and our outstanding reputation in audio recording technology. How
did we get here? Well, there were no great plans to ake SSL into a ajor anufacturer of ixing
consoles when it all started back in the seventies - the co pany began with nothing ore than an
enthusias for usic and the concept of recording. Along the way that spirit, coupled with a
passion for excellence in usic recording tools, helped build a ulti- illion dollar international
business. The SSL HQ ay be a little bigger now than it was in the seventies, but passion and
innovation still lies at its heart.
In 2005, we decided to e bark on a technology project to figure out how we could take the
processing power of a console and squeeze it into a 1U rack, so we could serve up the SSL sound to
ho e and project studio owners who don’t have the budget (or the floor space!) required to install
a large-for at console.
Drawing on our unique understanding of audio processing and years of DSP know-how, our tea
of engineers set about creating the SSL processing solution for your DAW environ ent. We knew
we needed serious DSP horsepower to acco odate our powerful algorith s, and we knew it
had to co e in a package that could integrate sea lessly with the ost popular workstations
… and so Duende was born.
Based on the digital technology behind SSL’s C-Series consoles, Duende delivers the co plete SSL
ix experience – powerful channel and dyna ics processing and the legendary Bus Co pressor.
Duende offers co plete integration into the ost popular workstation environ ents with one
si ple FireWire cable connection. The different processing blocks appear as VST/AU/RTAS plug-
ins – and include an authentic SSL channel strip with filters, E and G series EQ and dyna ics
processing, as well as the legendary SSL Bus Co pressor.
Oh, you’re probably wondering about the na e, right? It was a hot day, so eone in the tea had
bought in a CD of fla enco guitar usic and one of the tunes, ‘Duende’, just kind of hung in the
air. So ething inspired us to discover that in fla enco culture, Duende is a word for spirit, soul,
it’s the force that inspires the usic. That just see ed to sit well as a description for the 1U silver
box before us. We hope you will enjoy ixing your usic with Duende.

5. Operational Overview
Once your Duende hardware and software has been properly installed, Duende plug-ins are
accessed and used just like any host-based plug-in. You can run Duende plug-ins si ultaneously
with your other host based plug-ins in any co bination.
All Duende plug-ins support up to 40bit 96kHz operation. Please note that Duende plug-ins use
twice as uch DSP resources at 96kHz.
Duende para eters are changed by dragging, rotating or clicking knobs and buttons, whose
behavior varies slightly depending on which software is being used to host the plug-ins. Generally
the further away the ouse pointer is fro the knob, the ore resolution is available for
para eter adjust ent.
When the ouse cursor is hovered over a knob it’s value is displayed in the appropriate units. At
any point you can see exactly what value a knob has without touching it. If you have a ouse with
scroll wheel, it can be used to change the knob position.
OS X:
To reset a knob to its default value hold 'COMMAND' whilst clicking on that knob.
For very fine adjust ent, hold 'SHIFT' whilst dragging.
Windows XP:
To reset a knob to its default value hold 'CTRL' whilst clicking on that knob.
Every Duende plug-in para eter can be auto ated so long as para eter auto ation is supported
by the host application. The ethod for recording and editing auto ation varies fro host to host.
For specific instructions on using auto ation with the host consult the host application
docu entation.

5.1 Duende Preferences/Control Panel
OS X Windows XP
The Duende Preferences/Control Panel shows infor ation about your Duende such as serial no
(Authentication ID), fir ware version and driver version. It also displays DSP resource
infor ation and allows you to easily see how uch DSP you have available at any ti e.
OS X:
The panel can be found by navigating to 'Apple Menu>Syste Preferences>SSL Duende'.
Windows XP:
The panel can be found in ‘Start Menu>Proga s>Solid State Logic>Duende’ or in the Windows
control panel.
Each ono plug-in loaded into Duende will take up one slot, a '1' representing a used slot and a '- '
representing an unused slot. At 44.1 and 48kHz there are 32 slots available and at 88.2 and 96kHz
there are 16 slots available. A stereo version of a plug in will take up 2 slots.
5.2 Launching a Duende plug-in
Each host application has its own particular ethods for instantiating (launching) a plug-in.
Consult the host application docu entation for specific instructions on loading and using plug-ins
within the application.
