Controlling Parameters

Double click a virtual mixer in the Access branch to open the access view. For a better workflow, it is possible to open several DSP control views at once in different tabs to be able to quickly switch between them.

Example of a DSP control view

Depending on the Feature Manager settings, the Fader Channels and Fixed Processings the user is allowed to use, are listed in the Items list. The associated faders of the listed Fader Channels are shown in a separate view.

Select a Fader Channel or a Fixed Processing of the list to edit its parameters. The parameters of the Fader Channels and Fixed Processings can be controlled in 3 different ways:

• Live DSP Control: Direct control of the console parameters.
• Preselection Mode: This working mode allows to adapt several parameters and to apply all settings to a Fader Channel or a Fixed Processing afterward. Moreover, parameters of several Fader Channels and/or Fixed Processings can be modified to transfer all settings together to the device.
• Snapshot Mode: Basically, this working mode is similar to the Preselection Mode, but it is intended to edit mixer and channel snapshots.

The main view is split into two parts. On the left-hand side, two graphical views are located. The upper graph shows the compression ratio and the gain reduction; the lower graph displays the filter settings. On top of the right-hand side of the window, a peak meter is shown. This peak meter visualizes the level of the input signal. Below, all assigned DSP functions and their options are displayed. Which DSP functions are assigned to a Fader Channel or a Fixed Processing is defined in the TB8 configuration (TB8: DSP functions of Fader Channels > Mixer / Channel Assignment, DSP functions of Fixed Processings > Audio / Fixed Processing). Please see the Toolbox8 Manual (sections: Channel Assignment, Fixed Processings) to find out, which DSP functions are available in general. Furthermore, the parameters and the usage of the DSP functions are explained in these sections of the TB8 manual.

Basically, all DSP functions are working in an analogous manner as it is known from the hardware.

There are 3 possibilities to control the potentiometers of the DSP Control software:

1. Left-click and hold a potentiometer with the mouse and move the mouse cursor around the potentiometer to set the desired value.
2. Select a potentiometer with the tabulator key or the mouse and set the values using the keyboard. (Usable keys: Right Arrow = one step up, Up Arrow = one step up, Left Arrow = one step down, Down Arrow = one step down, Page Up = several steps up, Page Down = several steps down, Home = minimum, End = maximum)
3. Select a potentiometer with the tabulator key or the mouse and use the mouse wheel to set the values.

The headings of the DSP functions on the right-hand side are highlighted by several colors. These colors emblematize the following functional groups:

• blue = Dynamics (Compressor, Limiter, etc.)
• orange = Filters (EQ, Sub Sonic, etc.)
• gray = Basic and special functions (Input Gain, Pan/Bal, Generators, etc.)

It is easy to use the possibility to set the Gain and Frequency values of the equalizer bands. In the lower graph, for each equalizer band, a symbol is shown. For example is equivalent to the first band of the equalizer (EQ1). By dragging and dropping such a symbol , you can change the gain and frequency values of an equalizer band, depending on the direction you move it in the graph.

If the Faders entry is selected in the Items List, all faders are listed, where A and B characterize the two possible layers of each fader. The current position of each fader is shown in a graph and as a number. Please note that these values do not show the actual value of the signal, but the physical position of the fader. In the Signal column the label of the currently assigned Fader Channel is displayed.

Faders in the Live DSP Control Mode

On the contrary, in the Preselection Mode and the Snapshot Mode the current fader values are not displayed, but in these modes, you can set the fader values to 0dB and -∞ dB with the buttons on the right side and you can apply these settings to the device or save them to a snapshot. Moreover, on the right side, a list of all Fader Channels is shown that are currently not assigned to a physical fader. Using the arrow key or by drag & drop, you can assign signals of this list to faders. Afterwards, the Fader Channel label is displayed in the New Signal column and the currently assigned signals are moved to the list.
