Apollo Software Manual Chapter 5: Unison 86
• If Apollo is disconnected from the host computer (standalone mode), the Unison
plug-in can no longer be controlled from Apollo’s front panel. However, the signal
continues to be processed by the Unison plug-in, using the values that were active
when the connection was lost. Note that if Gain Stage Mode is active when the
host connection is lost, the gain stage can apparently be switched from the front
panel. However, the actual gain stage being controlled does not change.
