1. Introduction Congratulations on your purchase of Duende PCIe – 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 fo

4. Operational Overview Once your Duende PCIe hardware and software has been properly installed, Duende PCIe plug-ins are accessed and used just like any host-based plug-in. You can run Duende PCIe plug-ins simultaneously with your other host based plug-ins in any combination. All Duende PCIe plug-ins support up to 40bit 96kHz operation. Please note that Duende PCIe plug-ins use twice as much DSP resources at 96kHz. Duende PCIe parameters are changed by dragging, rotating or clicking knobs and b

4.1 Duende PCIe Preferences/Control Panel Windows XP OS X The Duende PCIe Preferences/Control Panel shows information about your Duende PCIe(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

4.3 DSP Resource Management Due to the Duende PCIe having multiple DSP chips, a The way to handle this is as follows: minimal amount of resource management should be done 1. Save your project/song when running Duende PCIe 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 PCIe will under certain conditions 3. Re-open project/song notify you that you are out of DSP resources. This will only When this has been done Duende

Compensating for latency in Pro Tools LE and M-Powered PDC No PDC Because Pro Tools LE and M-Powered do not feature PDC it Final Cut Pro Steinberg Cubase 4 must be done manually when Duende PCIe plug-ins are used. Due to the nature of how signals are sent to and from Duende Soundtracks Pro Steinberg Cubase SX 2 & 3 PCIe, a latency is introduced which will delay any audio track, aux input, master fader or instrument track by a specific Garageband Steinberg Nuendo 2, 3 & 4 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 PCIe 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 PCIe plug-ins are loaded. Note that if Duende PCIe channel an audio track with 1 Duende PCIe plug-in is routed to an aux strip loaded onto it, channel with 2 Duende PCIe plug-ins the total latency for that therefore Pro To

5. Duende PCIe EQ and Dynamics Channel Strip 5.1 Introduction The Duende PCIe 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

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 S/C overrides the 20Hz to 500Hz. In addition, each filter has an OUT position INPUT function (see below). which bypasses the filte

Based on the XL 9000 K Series EQ circuit, this plug-in includes two distinct EQ curves, one based on the SSL G Series EQ and another based on the latest version of SSL’s classic E Series EQ. The G series EQ bandwidth varies with applied gain and so

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
