The One Remote for TotalMix FXThis wired remote has been designed for direct access to the most frequently used actions and commands of TotalMix FX, being an indispensable tool in the studio's daily applications. Its extremely flexible configuration through TotalMix FX will simplify workflow and greatly increase the usability of the RME interface in most real-world situations.The ARC USB is a USB 1.1 (UAC1) MIDI remote control, natively compatible with Windows and Mac OS X. As soon as it is present in the operating system, TotaIMix FX will detect it and communicate with it, without disturbing other remote controls. Therefore, it is also not necessary to switch the ARC USB on or off within TotalMix FX - it will just work.Control several interfaces simultaneouslyAnd because it communicates with TotalMix FX (via USB), it is compatible with all RME audio interfaces that are detected and supported by TotalMix FX. This goes back to the RME interfaces released in 2001! As soon as the ARC USB is connected to a computer, any button press or wheel turning will cause the respective action performed by TotalMix FX - and therefore also by the RME audio interface.Direct Device ConnectivityThe ARC USB can also be connected directly to our latest devices, featuring an internal USB 1.1 host with a matching connector. This way of connecting is handy in stand-alone mode, where the ARC USB is supported by the UFX Series, 802 FS, UCX II, and MADIface XT II.Efficient Power and Reliable USB PerformanceThe ARC USB is bus-powered, but draws only a little current. Also, it uses USB 1.1 as a bus standard, which these days is uncritical due to its lower frequency and speed demands. USB 2 cables with 5-meter to 10-meter length, and cheap USB 2 cable extensions that usually make a bus-powered interface fail, will work perfectly for the ARC USB. Still at higher lengths, RME recommends using active USB 2 cables (also called extension or repeater cables), which are not expensive and work over lengths of more than 20 meters.Seamless Multi-Interface ControlThe ARC USB can control several interfaces simultaneously, which happens automatically as the Key Commands dialog in TotalMix FX is specific to the currently selected audio interface. Just assign only the functions that are desired for each respective interface. After that, the ARC USB keys and the encoder wheel remote are connected to the respective interface where they have been assigned to, without the need to further switch or select anything in normal operation.
