Apollo Solo USB Manual Unison 177
Unison Operation Notes
The operating notes in this section only apply to Unison functionality (when a Unison plug-in is
loaded in Console’s dedicated Unison insert).
These notes do NOT apply with Unison plug-ins that are used in Console’s standard inserts,
nor via VST/AAX 64 plug-ins within a DAW, even when a Unison plug-in title is used. In this
scenario, Unison plug-ins function the same as all standard (non-Unison) UAD plug-in titles and
there is no physical or electrical hardware interaction.
Note: Unison functionality is available only when Unison-enabled UAD plug-ins are
loaded within Console in the dedicated Unison inserts.
• Caution: 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 +48V and PAD. See Loading Sessions: Hardware
settings are overridden for additional details.
• Unison insert processing is always recorded in the DAW (regardless of the current
Channel Insert Effects setting) because Unison plug-ins process the physical inputs.
• When a channel strip preset is saved from a preamp channel, the channel strip preset
contains the state of the preamp channel’s Unison insert.
• When a preamp channel strip preset is loaded into a preamp channel, the Unison insert
state is replaced by the Unison instance state in the preamp channel strip preset. For
example, if the preamp channel strip preset’s Unison insert is empty, the Unison insert
will be empty after loading the channel strip preset.
• Apollo Solo USB’s top panel preamp controls are always current. Therefore, changes
made to a Unison plug-in when the plug-in is bypassed are not retained when the plug-in
is reactivated.
• A Unison plug-in’s modeled behaviors and parameter ranges are used by the hardware
controls whenever possible, even if the attribute is different than Apollo Solo USB’s stock
preamps. For example, if the Unison plug-in has a 15 dB pad, then Apollo Solo USB’s
top panel PAD button value will use the Unison plug-in’s 15 dB value instead of Apollo
Solo USB’s stock 20 dB value.
• Default gain levels when a Unison plug-in is inserted can vary from Apollo Solo USB’s
default (non-Unison) preamp levels, and also between various Unison plug-in titles. This
is a by-product of accurate preamp modeling. Because hardware preamp designs from
each manufacturer vary, they all have different total gain amounts, control ranges, and
control response curves, whether Mic, Line, or Hi-Z.
