Chapter 20: Snapshots 201
Making Changes to Snapshots
There may be situations where you need to change specific pa-
rameters in existing snapshots while leaving other parameters un-
changed.
For example, if a guitarist changes instruments in the middle of a
tour it might be necessary to change levels and EQ on the guitar
channel in all the snapshots in a show. Snapshots provides the fol-
lowing modes to accommodate these types of situations:
Edit Mode Lets you capture individual control changes while you
mix, and apply those changes to one or more pre-existing snap-
shots as absolute or relative changes. For example, you could en-
ter Edit mode the first time a guitarist uses a new guitar in re-
hearsal. When you are satisfied with your settings you can apply
them (in absolute or relative fashion) to update other snapshots.
See “Using Edit Mode” on page 201.
Propagate Mode Lets you update data in pre-existing snapshots
after you've already made changes and decided you want to keep
them. While Edit mode requires you to know ahead of time that
you will be updating snapshots, Propagate mode lets you decide
to update other snapshots with current settings after making ad-
justments to your mix. For example, if its the third consecutive
night you’ve reached to increase gain on the DI channel for a new
guitar, you could use Propagate mode to quickly take the gain in-
crease you just made and apply it to other snapshots. See “Using
Propagate Mode” on page 202.
Using Edit Mode
Edit mode is a powerful way to update specific parameters across
multiple snapshots without overwriting any settings you want to
preserve. By entering Edit mode before making adjustments, you
can edit a single control or any number of controls, and your
changes are tracked from the point Edit mode was entered.
Absolute and Relative Edits
Changes can be applied to one or more selected snapshots as ab-
solute or relative values. Any parameter can be edited in absolute
fashion; all dB parameters can be edited in relative fashion.
Examples of Absolute and Relative Edits
Absolute Changing a fader level from 0 dB to –3 dB and apply-
ing that change as Absolute results in that fader being set identi-
cally to –3 dB in all selected snapshots.
Relative Changing a fader level from 0 to –3 dB and applying that
change as Relative results in that fader being reduced by that
amount in all selected snapshots, or 3 dB relative to the value pre-
viously stored in the snapshot(s). For example, a channel previ-
ously at –6 dB would be changed to –9 dB.
Making Relative Changes with Mixed Data Types
If a combination of dB and non-dB parameters (such as gain and
EQ frequency) are edited and applied in relative fashion, the dB
parameters are adjusted as relative (delta) changes and the
non-dB are applied as absolute changes.
To update specific parameters in existing snapshots using Edit
mode:
1 Go to the Snapshots page and click the Main tab.
2 Click the Edit button to enter Edit mode. The Edit button
changes into two smaller flashing buttons:
Abs, and Rel. The
system begins tracking all changes while you make them.
3 Adjust any combination of scopable parameters.
4 Select the snapshot(s) to which you want to apply your edits.
5 Click either of the flashing buttons Abs (for Absolute) or Rel
(for Relative). You can cancel Edit mode by pressing the
Can-
cel
switch on the control surface, clicking the Cancel button
on-screen, or by pressing the ESC key on your computer key-
board.
The selected snapshots are updated according to your changes
and your choice of Absolute or Relative edit.
Events-driven recall of snapshots is disabled while in Propa-
gate or Edit mode. For more information, see Chapter 21,
“Events.”
The ability to edit a single control in Edit mode provides more
selectivity than Propagate mode.
