This topic describes what is saved and loaded by snapshots.

What's Stored in a Snapshot?

The following settings are saved in all snapshots:
  • Fader Strip Assignments – the assignment of sources and buses to all fader strips.
  • User Labels – the two user label text lines for all sources and buses.
  • Stream subscriptions – the AoIP stream subscriptions handled by a RAVENNA pool.
  • Input Parameters – mic gain, 48V, etc. for all sources.
  • DSP Parameters – EQ, Dynamics, etc. for all sources and buses.
  • Fader Levels – the fader levels for all sources and buses.
  • Bus Assignments – the assignment of sources to summing buses and their send levels.
  • Insert Assignments – the assignment of insert devices.
  • VCA Assignments – the assignment of slave faders to VCA groups.
  • Logical States (optional) – up to 32 logical states defined by the ON-AIR Designer configuration (via "System -> Definition -> Parameter = Logic Snapshot").
  • Matrix Connects (optional) – up to 128 matrix connections defined by the ON-AIR Designer configuration (via "System -> Definition -> Parameter = Matrix Snapshot").

Snapshot Recall Options

The following options control what happens when a snapshot loads. They can be used to protect fader levels, isolate fader strips, or make the loading of source parameters dependent on the fader status.

All options apply to both the system and GUI snapshots. They are set by the system configuration and can be edited using the ON-AIR Designer.

Production Mode (Save Value)

This option determines whether fader levels are reset by a snapshot load. It can be reached using the Treedefinition path: "System → Definition → Parameter = Fader".

  • Production Mode (disabled) = fader levels are ignored (not loaded). Recommended for on-air systems.
  • Production Mode (enabled) = fader levels are loaded. Recommended for production systems.

Load max. Fader No., Load Audio Always

The "Load max. Fader No." option can be used to isolate all fader strips above a certain number. This can be useful if there is more than one operator and you wish to use snapshots to reset some faders and not others. It can be reached using the Treedefinition path: "System → Definition → Parameter = Snapshots".

  • Load max. Fader No. - defines the maximum fader number you wish to reset. Any fader above this number is excluded from snapshot loads. Leave the field blank to apply snapshot loads to all faders.
  • Load Audio Always - overrides the "Load max. Fader No." option for audio-related parameters. This allows audio parameters to be reset for all faders while fader strip assignments are excluded above the "Load max. Fader" number.

SnapLoad disable

This option can be used to isolate specific fader strips. It can be used as an alternative, or in addition, to the "Load max. Fader No.". It can be reached using the Treedefinition path: "Surface -> Fader Module" (via Snapshots tab).

  • SnapLoad disable (Default Map) - when active, snapshot loads are disabled for the fader strip.

Enable Load Groups Logic

This option can be used to make the loading of source parameters dependent on the fader status. For example, to allow snapshots to reset input parameters only if source faders are closed. It can be reached using the Treedefinition path: "System → Definition → Parameter = Snapshots".

When the "Enable Load Groups Logic" option is ticked, all snapshot loads become dependent on the fader status. By default, all parameters load if source faders are closed, and do not load if source faders are open. You can modify this behavior by assigning control signals to the FC: Disable... and FO: Enable... fields. For example, if FC: Disable Input Load is set to active, then input parameters are not loaded if source faders are closed.

In each case, FC = Fader Closed and FO = Fader Open, and control signals can be applied to each of the following source parameter groups:

  • Input - input parameters (mic gain, 48V, etc).
  • DSP - EQ, Dynamics, Limiter and Delay.
  • Bus - summing bus assignments.
  • Insert/VCAGrp - insert and VCA Group assignments.

Note that the FC: Disable... and FO: Enable... fields are hidden until the "Enable Load Groups Logic" option is enabled (ticked).
