5.2. A/B Button
The A/B button is a new feature introduced with the current version of Arturia plug-ins.
This button allows to compare between two distinct snapshots of the current preset, like
for example the currently edited version, with all the changes you made, and the stored
version. The snapshot in use is the highlighted one. This is great to perform some changes
in a preset, and check if those really match what you want and are an improvement when
compared to the original settings.
All presets may have a snapshot A and a snapshot B (these can be a completely different
settings configuration, a variation of the main preset, an edited preset or just the current
state of the plug-in). You can copy the settings of the A snapshot into B and vice-versa. When
a preset is loaded, the settings are the same for both A and B snapshot. Therefore, if you
start editing the preset when in snapshot A, snapshot B will preserve the original settings
until you save the changes. This way both the original preset and the edited version can
always be recalled for comparison.

♪: If you want to copy the settings on A to B or vice-versa, select the snapshot you want to copy
from (the source) and click over the arrow. This will make the settings of that snapshot to be copied
over the other snapshot. Notice that the arrow is always pointing from the currently selected snapshot
to the other one: Source -> Destination
Another interesting and very handy feature of the A/B button is the possibility to have two
presets loaded simultaneously, and compare between them. When you load a preset having
this button for example in position A, the preset loads in position A (position B assumes the
same settings). However, if you change to position B and load another preset, this will not
overwrite the settings in position A, which will keep the previous loaded settings. You can
then change between position A and position B and compare both presets.
When you save a preset only the settings for the currently selected snapshot are stored.
Therefore, if you save the preset with the B snapshot selected, the settings of the B snapshot
are the ones saved. If you save the preset with the A snapshot selected, the settings of that
snapshot are the ones stored in the preset.
The same way, when you edit settings for the currently loaded instance of the plug-in, and
you save the project in your DAW, next time you load that project, both A and B snapshots
will have the same settings, reflecting the saved state of the plug-in.

♪: If you want to save both snapshots of a preset, you will need to save two presets. To do this, select
snapshot A, and in the Arturia sub-menu choose "Save As..." and save the Preset, giving it a name. Then
select snapshot B and do the same thing, giving it a different name.
