Apollo Solo USB Manual Unison 176
Unison Load/Save Behaviors
Caution: Apollo Solo USB hardware preamp settings (including +48V phantom power and
PAD) can change when Console sessions are loaded. Details are explained in this section.
Loading Unison Plug-In Settings
When Unison plug-in settings are loaded in Console, the effect on currently active Unison
plug-in settings varies depending on how the settings are loaded. It is important to understand
this distinction, because critical preamp settings can be affected.
Note: When Unison plug-ins are used in Console’s standard inserts and/or within a DAW,
this section does not apply. Settings load behavior outside of the Unison insert is like all
other (non-Unison) UAD plug-ins.
There are two ways Unison (and non-Unison) plug-in settings can be loaded in Console:
• Plug-In Presets – UAD Presets are loaded whenever a UAD plug-in is inserted (the default
preset loads). Presets can be loaded from disk files via the Presets Manager or the UAD
Toolbar. Preset files are used to save & load all settings of individual plug-in titles.
• Console Sessions – Console sessions are loaded from disk via the Sessions Manager
Popover, the Console Recall plug-in within a DAW, or by double-clicking Console session
files on disk. Console sessions are complete Apollo Solo USB configurations, containing
all hardware and plug-in settings (i.e., Console sessions are Console presets).
Loading Presets: Hardware settings are inherited
When a Unison plug-in is loaded in the Unison insert and a preset is loaded into the plug-in,
the plug-in inherits the current equivalent hardware settings of the Apollo Solo USB preamp, if
those settings are available in the plug-in.
In other words, Apollo Solo USB’s preamp settings always override a Unison plug-in’s settings
when a preset is loaded or the plug-in is inserted. This is done to prevent the plug-in’s settings
from switching the hardware to values that could cause extreme level changes and/or other
unwanted circuit changes such as +48V phantom power.
For example, if the PAD is ON in the Apollo Solo USB preamp, when the Unison preset is
loaded, the pad setting in the plug-in is enabled to prevent unexpected level increases.
Loading Sessions: Hardware settings are overridden
When a Console session is loaded (via Console Recall menu, DAW sessions containing the
Console Recall plug-in, or double-clicking Console files on disk), ALL Console settings are
overridden (changed) by the saved session, INCLUDING ALL Apollo Solo USB HARDWARE
PREAMP SETTINGS such as PAD and +48V.
In other words, Console sessions always override Apollo Solo USB’s preamp settings, even if
potentially harmful preamp settings are contained in the session file. This is done because the
very concept of Console session recall is to exactly reproduce all settings in the session.
For example, if PAD and +48V are OFF in the Apollo Solo USB preamp, when a Console session
with PAD and +48V enabled is loaded, the PAD setting in the plug-in is disabled and +48V in
the plug-in is enabled. In this case, sensitive equipment could be affected, such as speakers
(level increases) and/or ribbon mics (+48V phantom power).
