Recalling Snapshots
Recalling a Snapshot can cause destructive actions such as building and/or reordering of
plug‑in chains. Therefore, when a Snapshot is recalled, channels may be muted to avoid
audio artifacts.
If a Snapshot is loaded that has the same plug‑in configuration as the currently loaded
Snapshot, the plug‑ins are not rebuilt and only parameter values are changed, enabling a
(mostly) artifact‑free Snapshot recall workflow.
Caution:
When SAFE mode is active, Snapshots can still be recalled, which can
potentially overwrite current plug-in assignments and cause audio artifacts during
live a performance.
Base Snapshot Workflow
Recalling Snapshots can be potentially destructive in that entire plug‑ins and plug‑in
channel strips can be torn down and re‑built, potentially causing audio artifacts and/or
silence for the duration of the Snapshot loading process.
For this reason, it is highly recommended that a “Base Snapshot” be prepared that
contains all of the plug‑ins required to get through a show/performance and only create
snapshots that are saved as variants of the base snapshot.
Important:
Recalling Snapshots created using the method below will result in
parameter values being changed without significant glitches or muting.
To create Snapshots variants from a base Snapshot:
1. Create the base Snapshot by loading as many plug‑ins as needed for the show/
performance/session.
2.
.
3. Click SAVE AS to save and name the base Snapshot file.
4. When a change is needed (for example, for a change in the song or a different
song that needs new settings), click SAVE AS again to create and name the
variant Snapshot.
5. Make the parameter changes needed in the variant Snapshot and press
.
This locks the parameter change deltas into the variant Snapshot file.
6. Repeat steps 4 and 5 for all the variant snapshots that are needed.
The base and variant Snapshots can now be switched with minimal artifacts.
