Path Processing

Fully processed paths (or Full Paths) include EQ, Dynamics and Delay sections as well as an All Pass Filter.


EQ

EQ

All Full paths have a 4 Band Parametric EQ and a High Pass and a Low Pass Filter.

To access the EQ, open the Detail View and select the EQ page.

To switch the EQ or filters in or out, touch the EQ IN or Filter IN button (in the top-right of the page) – each button 'lights' when it is switched in.

You can drag the nodes within the EQ graph using a finger or the mouse button. To change the Q value, use the pinch gesture narrow or widen the shape of the curve.

EQ Shapes

Each band of EQ and filters has three shape options, which are different for each type of band.

On filter bands, these options allow you to select the filter gradient between 12 dB, 18 dB or 24 dB attenuation per octave.

On EQ bands, the following shapes are available:

Band 1 (LF): Low Shelf (with adjustable Q allowing overshoot/undershoot at corner frequency), ConstantQ (where the Q is adjustable but constant as gain is changed) or Legacy (which emulates the Q behaviour of a typical SSL G-Series EQ).

Band 2 (LMF) and Band 3 (HMF): ConstantQ, Legacy or Notch (set to maximum gain reduction at the centre frequency; Q and frequency can be adjusted in the usual way).

Band 4 (HF): High Shelf (with adjustable Q allowing overshoot/undershoot at corner frequency), ConstantQ or Legacy.

To change the band's shape:

Touch the relevant band's node – it will be coloured to indicate it is selected;

Touch the button to the right of the graph, below the Filter IN button to open a menu with the shape options and select the desired shape.

The EQ graph

The Detail View's EQ graph provides a very precise display of the frequency response of the EQ and filters, both as individual bands and as in overall effect.

Resetting the EQ

To reset individual EQ or filter bands, press the Band Reset button to the right of the EQ graph and select the required band from the drop-down list.

To reset the entire EQ and/or filters to flat, press & hold the EQ IN or Filter IN button (in the Detail View) and select the Reset option from the drop-down list that appears.


Quick Controls

Follow Detail

The Quick Controls beneath the screen can also be assigned to the Detail View parameters. This requires the Follow Detail button (bottom right corner of the Main Screen) to be activated.

With Follow Detail on, the Quick Controls below the screen are assigned to different functions for the selected channel (only applicable when the Detail View is open). The Quick Controls on other Fader Tiles are unaffected.

The labels across the bottom of the Detail View indicate the functions assigned to the Quick Controls directly beneath them. As a general rule only one function is assigned to each Channel's Quick Controls. Switch functions are assigned to the Upper Quick Key (which will be lit if available) and continuous parameters are assigned to the Encoder.

Follow Channel Quick Control Mode

Tap once on the EQ section of the Channel View or the Detail View to send the Filters/EQ to the Quick Controls.

Press the Fader Tile Encoder (or double-tap the Screen Encoder) to cycle the controls between the four EQ bands (cyan) and two filter bands (purple);

Switch the EQ into circuit by pressing the In button in any of the four equaliser band pages. Similarly, to switch the filters into circuit, press the In button in the filters page;

For equaliser bands, use the bottom two Quick Control buttons to switch the Encoder's parameter between the band's frequency (left button lit), gain (right button lit) and Q (neither button lit);

For filter bands, use the bottom two Quick Control buttons to switch the Encoder's parameter between hi-pass frequency and lo-pass frequency;

Now drag the Encoder to adjust the selected parameter.

The Context display displays the current EQ settings. A simplified version of this graph is also shown in the EQ button-cap, which will stay visible when the Context Display isn't displaying EQ.

Double-tap in the Context display to open the channel EQ Detail View, where you can edit more advanced EQ parameters.

If the gain control for an EQ band is greyed out, its band is probably set to 'notch'.

Control Tile

To switch the four EQ bands in or out, press the EQ IN button in the EQ area beneath the screen; To switch the filters in or out, touch the Filters IN button.

To reset the EQ bands or Filters, press & hold the appropriate IN button until it flashes.

The graph in the middle of the screen indicate the current EQ and filter settings.

You can also adjust the graphic using touch.

The encoders down each side of the screen are assigned to the frequency, Q and gain of the four EQ bands, as indicated in the screen area nearest to them; to change a band's EQ shape, press its Q encoder and cycle through the settings which appear below the Q value bar.

The filter frequencies are controlled at the bottom of the screen; touch the buttons above each frequency value bar to select the filter slope.

All on-screen buttons can be controlled by touching the screen.

Dynamics

Dynamics

All Full paths have a Compressor and a Gate/Expander.

To acces the Dynamics section, open the Detail View and select the Comp Gate page.

To switch the Compressor or Gate in or out, touch the Comp IN or Gate IN button (in the top-right of the page) – each button 'lights' when its dynamics element is switched in.

You can drag the nodes within the graphs displayed using a finger.

When two nodes are on top of each other, double-tap them to switch which one is selected.

To change the compressor or gate Hold value, use two fingers to pinch the Comp Time or Gate Time graph.

To change the compressor or gate (expander mode only) knee value, use two fingers to pinch the CT or GT node in the main graph.

Display Options

The buttons above the left-hand graph define which parameters are displayed, summarised as follows:

  • Compressor: Threshold and Ratio on the left of the page, gain in the middle, time parameters and Compressor Setup on the right;
  • Compressor AND Comp Filters: Filter frequencies on the left, Compressor gain in the middle, time parameters and Compressor Setup on the right;
  • Gate: Threshold and Range on the left, time parameters and Gate Setup on the right;
  • Gate AND Gate Filters: Filter frequencies on the left, time parameters and Gate Setup on the right.
  • Compressor AND Gate: Both Thresholds and Ratios on the left, Compressor gain in the middle, Compressor and Gate time parameters on the right.

The Dynamics Displays

A 'traffic light' gate meter is shown in the top-left of the graph whenever the gate is active: Red means signal is not being passed, green means that the gate is open, and amber means the gate is at the threshold level.

The basic routing of the module is mapped in the Setup pages for each dynamics module; each element shown can be activated by touching it, and goes green to indicate that it is active.

Compressor Gain

To adjust the compressor's make-up gain manually, ensure the Compressor is active in the page, and drag the COMP slider (in the middle of the page) up and down. You will see the left-hand graph change to reflect the gain introduced.

You can also allow the console to set the make-up gain automatically: Touch the Auto Gain button (above the COMP slider) – it will 'light' to indicate that it is active, and the slider will be deactivated.

Side-chain

The gate and compressor both have side-chains with filters and external input routing.

To insert high- and low- pass filters into the Compressor and/or Gate side-chains:

Touch the Filters button within the Compressor or Gate Setup display – it will 'light' to indicate that it is active;

Touch the Comp Filters or Gate Filters button above the left-hand graph – a frequency graph with HPF and LPF nodes will appear.

Drag the nodes to change the -3 dB points of each filter.

To route a different signal to the Compressor or Gate side-chain, touch the Comp Key Route or Gate Key Route button (to the right of the right-hand graphs) and locate the signal using the standard routing display which appears. (See Routing for instructions regarding the Routing displays.)

Now touch the Ext Key button in the Compressor or Gate Setup display to activate the external side-chain – it will 'light' to indicate that it is active.

To listen to the Compressor or Gate side-chain, touch the Comp Key Solo or Gate Key Solo button (above the right-hand graphs).

Note: The Key Listen Solo signals are routed to the Solo bus(es) specified under the channel's Misc Solo setting; see Solo for details.

Tube Emulation

You can introduce tube compressor emulation into the compression circuit:

Touch the Tube button within the Compressor Setup display – it will 'light' to indicate that it is active.

Expander Mode

The Gate can be switched into Expander mode by touching the Exp button in the Gate setup display.

Presets

To load a dynamics Preset for the channel, touch the Preset button (bottom-right of the page) and select a preset using the standard LIVE Preset page which appears.

Resetting dynamics values

To reset the compressor or gate to 1:1, press & hold the Comp IN or Gate IN button (in the Detail View) and select the Reset option from the drop-down list that appears.


Quick Controls

Follow Detail

The Quick Controls beneath the screen can also be assigned to the Detail View parameters. This requires the Follow Detail button (bottom right corner of the Main Screen) to be activated.

With Follow Detail on, the Quick Controls below the screen are assigned to different functions for the selected channel (only applicable when the Detail View is open). The Quick Controls on other Fader Tiles are unaffected.

The labels across the bottom of the Detail View indicate the functions assigned to the Quick Controls directly beneath them. As a general rule only one function is assigned to each Channel's Quick Controls. Switch functions are assigned to the Upper Quick Key (which will be lit if available) and continuous parameters are assigned to the Encoder.

Follow Channel Quick Control Mode

Tap once on the Dynamics section of the Channel View or the Detail View to send the Comp/Gate to the Quick Controls.

Press the Fader Tile Encoder (or double-tap the Screen Encoder) to cycle the controls between the Compressor (green) and Gate (light green);

Switch the Compressor or Gate into circuit by pressing the In button;

Use the Lower Quick Controls to switch the Encoder's parameter between CT and CR (Compressor Threshold and Ratio), or GT and GR (Gate Threshold and Range);

Now drag/turn the Encoder to adjust the dynamics.

The Context display displays the current gate and compressor settings. A simplified version of this graph is also shown in the Compressor/Gate button-cap, which will stay visible when the Context Display isn't displaying dynamics.

The actual gain reduction action is shown in the COMP and GATE meters on the console surface, to the right of the channel's fader.

Double-tap in the graph area to open the expanded display, where you can edit more advanced dynamics parameters.

Control Tile

Dynamics controls can be assigned to the Control Tile (to the right of the Main Screen) by pressing the DYN button in the Dynamics area beneath the Control Tile Screen:

To switch the Compressor or Gate in or out, press the Comp or Gate IN button in the Dynamics area beneath the screen.

To reset the Compressor or Gate, press & hold the appropriate IN button until it flashes.

You can also adjust the graphic using touch.

All on-screen buttons can be controlled by touching the screen.

The encoders around the screen are assigned to the functions in the screen area nearest to them, with the compressor controls down the left and the gate controls down the right.

Switches are operated by pressing the encoder, and continuous parameters are changed by turning the encoder.

Delay

Delay

The signal on each Full Path in Live can be delayed by up to 2 seconds.

Open the Detail View and tap on the Delay All Pass page.

To switch the Delay in or out, touch the Delay IN button (in the top-right of the page) – the button goes blue when it is switched in.

You can drag the Del node within the graph using a finger.

There is a scrollbar below the graph. The display will scroll if you attempt to drag the node beyond the left or right border.

You can change the delay by dragging the scroller. This will leave the node in its position in the display and scroll the graph behind it.

To zoom in and out, use two fingers and draw them together or apart.

The delay amount is shown in the top left of the graph. The Time and Distance buttons to the right of the graph define the units, with each button cycling through relevant units (samples/milliseconds/seconds, and centimetres/metres).

To set a precise delay amounts you can use the Delay Time – and + buttons below the unit buttons to increment the delay by a sample at a time. Alternatively, select the Del node, double-tap the value box in the bottom right corner and use the keyboard which appears.

Tip: You may find the following to be the most efficient way to operate the graph:
- Zoom in quite close on the graph and leave the Del node in the centre;
- Use the Scroller to set the rough delay value;
- Now move the Del node to perform fine adjustments to the value.
Note: The in-channel delay function is used for delaying the entire channel signal, not for creating delay effects. Delay effects can be routed to the channel inserts from the console's effects racks. See Effects Racks for more details.

Quick Controls

Follow Detail

The Quick Controls beneath the screen can also be assigned to the Detail View parameters. This requires the Follow Detail button (bottom right corner of the Main Screen) to be activated. Touch the button to toggle between:

The Quick Controls below the screen are assigned to different functions for the selected channel (only applicable when the Detail View is open). The Quick Controls on other Fader Tiles are unaffected.

The labels across the bottom of the Detail View indicate the functions assigned to the Quick Controls directly beneath them.

The Samples and + buttons allow you to make incremental changes to the delay value.

The Delay graph indicates the current settings.

You can drag the Del (delay) node within the graph using a finger.

The display will scroll if you attempt to drag the node beyond the left or right border.

You can also change the delay by dragging the scroller beneath the graph; this will leave the node in its position in the display and scroll the graph behind it.

To zoom in and out, use two fingers and draw them together or apart.

All Pass Filter

All Pass Filter

The All Pass Filter can be used to adjust the phase of a specific range of frequencies. The All Pass Filter is particularly useful to solve feedback issues in wedge monitors or when working with multiple microphones on the same instrument. A simple Ø invert button is most useful in situations where the phase relationship of two signals is close to exactly opposite, but often this is not the case. The All Pass Filter is a far more accurate tool to solve phase-related issues.

Open the Detail View and tap on the Delay All Pass button.

To switch the All Pass Filter in or out, touch the All Pass IN button (in the top-right of the page) – the button goes blue when it is switched in.

Define the filter type using the 2nd Order and All Pass Ø buttons.

You can drag the AllP node within the graph using a finger or the mouse button.

To change the Q (when in 2nd order), use the pinch gesture.

The filter's Q and centre frequency are shown in the top left of the graph.

To reset the filter to its default values, press & hold the All Pass IN button (in the Detail View) and select the Reset option from the drop-down list that appears.

Quick Controls
