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 sum buses to all fader strips.
  • User Labels – the two user label text lines for all sources and sum buses.
  • Stream subscriptions – the AoIP stream subscriptions handled by a RAVENNA source pool.
  • Input Parameters – mic gain, 48V, etc. for all sources.
  • DSP Parameters – EQ, Dynamics, etc. for all sources and sum buses.
  • Fader Levels – the fader levels for all sources and sum buses.
  • Bus Assignments – the assignment of sources to sum buses and their send levels.
  • Insert Assignments – the assignment of insert devices.
  • VCA Assignments – the assignment of faders to VCA groups.
  • Logical States (optional) – up to 32 logical states defined by the ON-AIR Designer configuration (via "System -> Definition -> Parameter = Logic Snapshots #").
  • Element States (optional) – up to 16 element states defined by the ON-AIR Designer configuration (via "System -> Definition -> Parameter = Element States Snapshots #").
  • Matrix Connects (optional) – up to 128 matrix connections defined by the ON-AIR Designer configuration (via "System -> Definition -> Parameter = Matrix Snapshots #").

Snapshot Recall Options

The system configuration supports a number of options to control which parameters are reset by snapshot loads.

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

Note that the Production Mode (Save Value) option is applied globally, while the global snapshot options can be different for each Access Group. The latter can be used in Power Core Max systems to support a different configuration for each surface/VisTool instance. For more information, please see Power Core Max.

Production Mode (Save Value)

The Production Mode (Save Value) option is reached via the following Treedefinition path: "System → Definition → Parameter = Faders" (in the Logic tab).

This option determines whether fader levels are reset by snapshot loads:
  • Production Mode (Save Value) disabled = all fader levels are isolated from snapshot loads. Recommended for on-air systems.
  • Production Mode (Save Value) enabled = all fader levels are reset by snapshot loads. Recommended for production systems.

Global Snapshot Options

The global snapshot options are reached via the following Treedefinition path: "System → Definition → Parameter = Snapshots #" (in the Access Grp tab).

From here, you can isolate certain parameters or fader strips, make the loading of source parameters dependent on the fader status, and define external control inputs (e.g. MF Keys) for the system snapshot operations: load, save and unlock.

The same parameters are repeated four times in a Power Core Max system (to support a different configuration for each Access Group).

Of particular note are:

  • Load max. Fader No. - isolate fader strips above a certain number. 
  • SnapLoad disable - disable snapshot loads on specific fader strips.
  • Enable Load Groups Logic - make snapshot loads dependent on the fader status. For example, to reset input parameters only if source faders are closed.
