Introduction

Description

Blue Cat's Stereo Parametr'EQ is a 7 bands parametric stereo equalizer based on Blue Cat's Parametr'EQ technology, providing the best of the analog and digital worlds in stereo.

This stereo plug-in enables you to manage separately the left and right equalizer settings and keep an eye on both frequency responses thanks to the frequency graph above the controls. The left equalizer is visible by its blue color and the right equalizer controls and graph are red. Left and right controls can be linked together with several modes. The Smooth Update and Smooth Bypass technologies have been included in this plug-in so that you can automate the equalizer in your favorite sequencer or use the MIDI capabilities of your host software to control the EQ in real time. You will get an absolutely zipper-free continuous time-varying equalization. These capabilities and the zero latency of this plug-in make it suitable for any real time application.

For more information about the Parametr'EQ technology and algorithms, please read Blue Cat's Parametr'EQ plugin's description.

Installation

The plug-ins versions cannot be run standalone: they require a host application (see the System Requirements chapter for more information). Depending on which host application you use, you might need to install the plug-ins in different locations.

Before installing one of the plug-in versions, you should close all your host applications.

Windows

Install

All versions of the plug-in provide an installation program. Follow the steps of the wizard to install the software on your machine. During the installation you will be asked where you want the software to be installed. For the VST version, you should install the plug-in inside the VST plug-ins folder used by your host application(s). The default path set in the installer should work for most applications, but you should check your host software documentation to know where it looks for VST plug-ins. For other plug-in types, you should just use the standard path.

Some applications will not automatically rescan the new plug-ins, so you might have to force a refresh of the plug-ins list.

Upgrade

When a new version of the software is released, just launch the new installer: it will update the current installation.

Uninstall

To uninstall the software, simply launch the "Uninstall" program that is available in the start menu or in the configuration panel. It will take care of removing all files from your computer.

Mac

Install

On Mac the plug-ins are available as drive images. After download, double click on the file to open it. You can then drag and drop the file(s) to the shortcut that is provided within the image. It will install the software for all users on the machine.

In case you do not have admin rights on your Mac or if you want to install the software to another directory, just copy the files to the appropriate location. If required, more information is available in the README.txt file that is included in the package.

Upgrade

When a new version of the software is released, open the new image and copy the files over the previous ones. The new version will replace the older one.

Uninstall

To uninstall the software, simply remove the component(s) from the folder where you have copied them during install (move them to the trash).

First Launch

Blue Cat Audio plug-ins cannot be run standalone, they require a host application (see the System Requirements chapter for more information). Some host applications will require you to scan the plug-ins before they are available in the application.

If the plug-in is not available in the application, please check that it has been installed in the appropriate directory (with no host application running), and that the host application has scanned it.

Using Blue Cat's Stereo Parametr'EQ

The User Interface

Note: The main toolbar, menus and basic features available with all our plug-ins are detailed in the Blue Cat Audio Plug-ins Basics section.

The Stereo Parametr'EQ effect is delivered with several skins. Some of them display the controls for a given channel at a time (you need to manually switch to the other channel), and some other skins display the controls for both channels at the same time. We will have a closer look to the default “single channel at a time” skin, since the other ones provide the same controls but with a slightly different layout.

  1. Activate each filter separately on the current channel. This enables you to lower CPU consumption if you do not activate all filters.

  2. Controls for the filters and in/out gain. You can select the shape of the filter (cut or shelf) for the low and high filters.

  3. EQ response graph: this graph shows the global response curve of the EQ for each channel (blue curve for left, red for right), and the response curve for the current filter you are manipulating (white curve).

  4. Output Meters: the meters in the center (green/red) show the output level of the plugin for the left and right channels, and the blue meters on the left and right show the compression amount, when the output limiter is activated

  5. Zoom: you can zoom the graph and sliders (change their range) by using either the blue slider on the left or clicking on the predefined range values (10,20 or 40 dB). This allows you to precisely manage the range of your EQ.

  6. Non linear behavior: these two sliders let you control the linear behavior of the filters. See the parameters or operation sections for more information.

  7. Window Opacity management: use this slider to make the plugin window transparent (this behavior heavily depends on your host application).

  8. Misc per-channel controls:

    • Auto-Gain: the user interface automatically adjusts the input gain to prevent distortion for the current channel

    • EQ control: shortcuts for all bands

  9. When moving the mouse over the graph, the position of the mouse is displayed at this place so that you can exactly measure the EQ curve you are applying.

  10. Misc general controls:

    • Bypass: bypass the plug-in (with smooth bypass transition, as opposed to most host bypass functionality)

    • Oversample: activate/deactivate oversampling

    • Limit:enable/disable the output limiter

  11. Channel switch: choose which channels controls you want to display (Left or Right). This switch does not exist in the skins which display both channels at the same time .

  12. Channels link control:

    • the “on” switch enables/disables the link between channels

    • Absolute/Relative: in absolute mode the values of the controls for both channels are identical, whereas in relative mode only controls variations are reported on the other channel (letting you setup a different EQ on each channel and then apply linked modifications for example).

    • Normal/Mirror: in mirror mode, the gain value for both channels are reversed. It is very handy when you want to use the EQ as a balance between channels.

The various elements of the user interface (knobs, sliders, buttons...) are simple and intuitive to operate, but more information about how to interact with them is available in the "Plug-ins Basics" chapter of this manual.

Operation

The EQ

To operate the EQ, you just need to activate the band you are interested in and move the slider and knobs to adjust the parameters of the filter. The EQ graph above is updated in real time. It is also possible to first adjust the filter curve visually (with the filter disabled) and apply the filter once it's setup. It is particularly useful in live situations where you may want the filter to be applied only when it's close to its final position. The activation of the filters is smooth and will not produce any artefact in the output.

This plugin offers independent settings for both channels. You can apply different EQ settings to the left and right channels. It is however possible to link both channels in various way and thus control both channels from a single slider:

Single Channel

When the L/R link is enabled and its mode set to "absolute", the plugin behaves just like a single channel EQ: both channels are processed with the exact same settings.

Multi Bands Balance

If you enable the Left/Right link in absolute mode and use the "Mirror" function the plugin will behave as a multiple bands balance. In this case you can choose to use only the left controls. Pushing the cursor up will balance the sound to the left whereas moving down will balance to the right for a given frequency range.

Artifical Stereo

Using the setup described above (Multiple bands balance), it is easy to transform a mono source to a stereo signal: you can change the balance of entire frequency ranges (you will however usually prefer not to change the balance of bass band), and thus create a stereo sound from a mono signal: you can pan the mids to the left, the highs to the right etc.

Non Linear Mode

This EQ offers the ability to introduce non linearities in the signal chain: by default the EQ is transparent and operates as shown on the upper graph, but it is possible to activate the non linear behavior by increasing the "Non Linear" parameter value. It controls the amount of "non linearity" of each filter.

Once this is activated, you can choose the balance of distortion versus compression applied in every filter. This lets you control the type of color added to the EQ.

With extreme settings and extreme boosts this EQ becomes a powerful distortion unit, with different amounts of distortion spread accross various parts of the spectrum. When using this capability extensively it is recomended to activate the "oversampling" function to limit unwanted artefacts, especially when boosting high frequencies.

The Output Limiter

In order to prevent from signal overshoot when manipulating the EQ, a simple brickwall limiter has been added at the end of the signal chain. We advise you to activate it when setting up the EQ. It can be deactivated later when you are confident with your settings.

You can also use the limiter to alter the sound of your track and trigger it on purpose by boosting the input gain, even though it does not offer many settings.

About Oversampling

Thanks to oversampling, the plug-in internally works at a higher sample rate. This is particularly useful when working with high frequency content at lower sample rates (such as 44.1 kHz).

Running in oversampled mode has several effects on sound quality:

  1. Filter curves are identical to analog filters when approaching the upper side of the spectrum:

  2. Non-linear mode potential artifacts are reduced: when working in non linear mode with very high settings (100% Non-linear and 100% distortion for example), the plug-in may produce aliasing artifacts on high frequencies. Use oversampling to avoid these digital artifacts and produce a warmer sound. Note that the produced digital distortion can be interesting as well in some cases.

The drawback of oversampling is of course CPU hit, since the plug-in will have to convert audio data and process much more samples. Note that if your host is already running at 96 kHz you may not need to use the oversampling functionality.

Tip: Use Automation!

Since this plugin integrates the smooth update technology, you can use and abuse of automation to create time varying widening or narrowing filter effects. It is also possible to control these variations in real time thanks to the ability of the plugin to be controlled via MIDI, as shown in our MIDI Wah tutorials (see the tutorials section).

Blue Cat Audio Plug-Ins Basics

This chapter describes the basic features that are common to all our plug-ins. If you are already familiar with our products, you can skip this part.

User Interface Basics

About Skins

Like all Blue Cat Audio plug-ins, Blue Cat's Stereo Parametr'EQ uses a skinnable user interface. It means that the appearance and behavior of the user interface can be entirely customized.

Especially with third party skins, the experience may be quite different from the one offered by the default skins that we provide. However, our plug-ins and our skinning engine have several standard features that will be available whatever your favorite skin. This is what is described in this chapter.

More information about custom skins can be found in the skins section.

Main Toolbar and Menu

Menu

If you right click on the background of the plug-in, the following pop-up menu appears:

The description of the commands associated to each menu item are available below.

  • About: displays the “about” dialog box.

MIDI control

Blue Cat's Stereo Parametr'EQ can also be remotely controlled via MIDI using MIDI CC ("Control Change") messages if your host application supports it. It is possible to customize the channel, control numbers and range used for each parameter in the MIDI settings panel available from the main menu (see the Plug-in Settings chapter for more details).

Controls

Examples

Here are a few examples of typical controls you will encounter in the user interface of our plug-ins:

slider slider knob button Text control

Interacting with Controls

You can interact with the controls of the plug-in interface either with the mouse or the keyboard.

Setting the keyboard focus on a control (so that it responds to key strokes) may be automatic (when you pass the mouse over it it gets focus) or manual (you have to click on the control to set the focus on it). Note that all host applications behave differently regarding keyboard handling. In some applications you may not be able to use all keys described later in this manual to interact with our plug-ins. It is usually made obvious to you to know the active surfaces of the skin (the places where you can click with the mouse): the mouse cursor usually changes when you can do something on a control. In the default skins delivered with the plug-in, the cursor changes to a small hand or an arrow to tell you when your mouse is over an active control.

Mouse

Various mouse movements will let you interact with the controls:

Mouse Interaction Action
Left Click Acquire focus and start dragging or push (button)
Left Click + Alt Key Set the value to default
Left Double Click Acquire focus and launch the “fine tuning” edit box (except button):
Right Click Set the value to default
Mouse Wheel Increment or decrement the position (focus required)
Mouse Drag Change the control position depending on mouse movement (except button)

Keyboard

All control widgets support the following keys (note that some of them are caught by the host and thus never forwarded to the control. For example in Steinberg Cubase SX you cannot use the arrow keys to control the plug-in):

Keys Common to All Controls

Key Action
Up Arrow Small increment of the position (up or right)
Down Arrow Small increment of the position (down or left)
Left Arrow Same as Down Arrow
Right Arrow Same as Up Arrow
Page Up Large increment of the position (up or right)
Page Down Large decrement of the position (down or left)
+ Small increment of the value of the control
- Small decrement of the value of the control
d Set to default value (same as mouse right click)
e Opens the 'fine tuning' window to precisely set the parameter:
SHIFT When the key is down, the fine tuning mode is on, and you can modify the value with better precision when moving the mouse, the mouse wheel or using the keyboard. Just release the key to get back to the normal mode.

Plug-in Settings

In addition to the controls offered in the main user interface, Blue Cat's Stereo Parametr'EQ has various settings that let you fine tune the behavior of the plug-in. You can choose to change these settings either for the current preset or globally for all instances of the plug-in.

The Global Settings Window

The settings available in this window apply to all instances of the plug-in, for all presets, if not overridden in the presets settings. Consider these settings as “default” settings.

Global Skin

You can change the default skin for all instances of the plug-in: write the skin file path in the text edit box or click on the button to open a file chooser dialog. If you have several instances of the plug-in opened in your session, you will have to re-open the user interfaces of these plug-ins to see the skin change.

Global MIDI Input Settings

For each parameter you can define a default MIDI channel and CC number. You can then control the plug-in with an external MIDI controller or one of our plug-ins that generate MIDI messages.

The following settings are available for each plug-in parameter:

  • Channel: MIDI Channel for the parameter control. If set to 0, the plug-ins will accept Control Change Messages from all MIDI Channels (MIDI Omni mode).
  • CC: Control Change Number.
  • Learn: click on this button to activate the MIDI learn functionality. When it is activated, you can move your MIDI controller, and the plug-in will automatically set the MIDI Channel and CC Number.
  • Enable MIDI: enable/disable the MIDI control of the parameter.
  • Response: response curve of the MIDI control: from very fast to slow control.
  • Min: minimal value of the parameter when MIDI controlled.
  • Max: Maximum value of the parameter when MIDI controlled.

Click here for full size screenshot
(generic screen shot, does not correspond to the actual plug-in parameters)

Note: if the Min value is higher than the Max value, the response curve will be reversed: increasing the control value will decrease the parameter value.

Note: if you double click on the parameter text control boxes for the max and min values, a “fine tuning” edit box will appear and let you change the min and max values with more precision:

The Current Preset Settings Window

In this window you can change the settings for the current preset of the current instance of the plug-in only.

Preset Skin

You can choose to use the global skin setting or to change the skin for the current preset. This way you can have different skins for different instances of the plug-in in the same session in order to differentiate them.

About Skins

Blue Cat's Stereo Parametr'EQ integrates Blue Cat's skinning engine that allows you to customize the user interface. You can download alternate skins for your plug-in at the following address:

http://www.bluecataudio.com/Skins/Product_StereoParametrEQ

If you don't find a skin that fits your need or if you want a custom one, you can choose to create your own skin.

Choosing the Skin

There are two ways to select the skin of your plug-in: you can change the default (or 'global') skin, or change the skin for the current preset only (either in the preset settings page or from the main menu). The global skin applies to all plug-in instances (choose this one if you want to use the skin used by default, regardless of the session or preset), whereas the current preset skin only applies to the current preset of the current plug-in instance (use this one if you want to change only the skin for the current session/preset).

Note: in some host applications, the plug-in window won't resize automatically when you choose a skin with a different size. In this case, just close the window and re-open it: it will be displayed with the right size.

Selecting Skins

The global skin (used by default if no preset skin has been selected) can be changed in the global settings pane. The current preset skin can be changed in the preset settings page , or from the main menu, using the "Set Preset Skin..." command.

Create a Custom Skin

You can create custom skins for your plug-in in order to adapt it to your exact needs. You can change its look and feel and make it completely integrated in your virtual studio!

Just read the Blue Cat's Skinning Language manual and download the samples for the tutorial on http://www.bluecataudio.com/Skins. You can get ready to create your own skins in a few minutes. You can then share your skins on our website.
