1. Introduction Congratulations on your purchase of 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 make SSL into a major manufacturer of mixing consoles when it all started back in the seventies - the company began with nothing more than an enthusiasm for mus

4. 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 simultaneously with your other host based plug-ins in any combination. All Duende plug-ins support up to 40bit 96kHz operation. Please note that Duende plug-ins use twice as much DSP resources at 96kHz. Duende parameters are changed by dragging, rotating or clicking knobs and buttons, whose behavior varies

4.1 Duende Preferences/Control Panel Windows XP OS X The Duende Preferences/Control Panel shows information about your Duende(s) such as serial number (Authentication ID), firmware version and driver version. It also displays DSP resource information and allows you to easily see how much DSP you have available at any time. Windows XP: The panel can be found in ‘Start Menu>Programs>Solid State Logic>Duende’ or in the Windows control panel. OS X: The panel can be found by navigating to 'Apple Menu

4.3 DSP Resource Management Due to the Duende having 4 DSP chips, a minimal amount of The way to handle this is as follows: resource management should be done when running Duende 1. Save your project/song at high load. 2. Close your project/song If there are, for example 2 slots free and you wish to load a stereo plug-in, Duende will under certain conditions notify 3. Re-open project/song you that you are out of DSP resources. This will only happen When this has been done Duende will be forced

Due to the use of firewire and the nature of how signals are sent to Final Cut Pro Steinberg Cubase 4 and from Duende, a latency is introduced which will delay any audio track, aux input, master fader or instrument track Soundtracks Pro Steinberg Cubase SX 2 & 3 by a specific amount.

To turn on ADC, go to ‘Setup>Playback Engine’ whilst Pro Tools is stopped and you will see a box labeled ‘Delay Compensation Engine’. Change the setting here to ‘Long (4095 Samples per channel)’. Pro Tools will then tell you that it will close and re-open your session after clicking the OK button in the dialogue box; therefore make sure you have saved your session prior to doing this. Also put the CPU usage limit to 85%. Pro Tools will now automatically compensate for any introduced latency of

This means that you can generally use up to 2 Duende As you can see in the plug-ins per channel without considering latency issues, but picture shown left the this will depend on the buffer size set in Pro Tools, the sample ‘kc merged’ channel has 1 rate and which Duende plug-ins are loaded. Note that if an Duende channel strip audio track with 1 Duende plug-in is routed to an aux channel loaded onto it, therefore with 2 Duende plug-ins the total latency for that audio getting Pro Tools is auto

5. Duende EQ and Dynamics Channel Strip 5.1 Introduction The Duende EQ and Dynamics Channel Strip plug-in is based on the EQ and compressor sections of the XL 9000 K Series console. SSL were the first manufacturer to feature dynamics and EQ on every channel on an in-line console with the SL 4000 B Series in 1977. The plug-in includes separate high and low pass filters, a four band parametric equalizer, an independent compressor/limiter and gate/expander as well as input and output gain adjustmen

5.3 Filter Section Using Filters The Filter Section includes a 12dB/Octave low pass filter and DYN SC: The Filters are switched into the sidechain of the an 18dB/Octave high pass filter. The low pass filter operates Dynamics section. The Equaliser can be switched into the from 3kHz to 22kHz and the high pass filter operates from sidechain independently. Note that DYN SC overrides the 20Hz to 500Hz. In addition, each filter has an OUT position INPUT function (see below). which bypasses the filter

The plug-in includes high and low frequency shelving equalizers (which can be switched to peaking curves via the BELL button) and two overlapping equalizers with adjustable Q. • The LF section operates over a frequency range of 40Hz to 600Hz and is capable of up to 16.5dB of cut or boost. Selecting BELL in this mode switches the equaliser to a peaking curve. • The LMF section operates over a frequency range of 200Hz to 2 kHz and is capable of ±20dB of gain with a continuously variable Q from 0.5
