ARC USB and UFX+ / UFX II in Stand-Alone Mode

In stand-alone mode of Fireface UFX+ / UFX II a fixed set of functions is activated on the keys:

Row 1: Setup 1-4
Row 2: Setup 5-6 x x
Row 3: Mono, Volume Phones 1, Volume Phones 2, DIM

Lower keys: DURec: Rec, Play/Pause, Stop

x = no function

The included stickers also offer the stand-alone layout.

In the UFX+ / UFX II display’s menu the way of operating the ARC USB can be configured for stand-alone mode. Those options are found under SETUP/REV, Options, Hardware/Diagnosis:

Standalone ARC Volume
Deactivates all keys. Only the encoder wheel works, with a fixed assignment to Main Volume.

This option is also a safety function in case the ARC USB is connected to the UFX+ / UFX II, but oper-ated online (with computer). When the system goes offline (computer removed, sleep state…) the functions on the keys change, because online mode changed to stand-alone mode. Operating the keys then could activate unintended functionality or changes.

Standalone ARC 1 s op
Each key has to be pressed for one second to activate the programmed functionality. This safety function prevents unintentional changes. It can be stored within the Setups, activating this mode automatically when such a Setup is loaded. When loading a Setup where this function had not been active this mode is automatically deactivated at the UFX+ / UFX II.
