38. Direct USB Recording
38.1 Overview
The Fireface UCX II can record and playback up to 40 channels of audio via the DURec USB
port on the rear panel. This functionality is provided by the internal DSP and is therefore inde-
pendent from a Windows or Mac computer connected via USB.
As all settings are also available directly at the unit it is possible to even record a whole live con-
cert completely without a computer. Music that was copied onto the stick earlier can be played
back anytime on any outputs.
The following chapters explain features, capabilities, but also restrictions of this functionality.
38.2 Operation
In
TotalMix FX the DURecorder panel controls the record and playback functions. The configu-
ration of record/playback is stored in the workspace, therefore identical in all eight Snapshots. In
case the panel is not fully visible minimize one of the other panles by a click on the arrow in the
respective title bar.
File selection.
Multi-purpose dialog. Displays detailed information on current
USB media conditions. No Media (no media recognized), Initializing (Medium is
currently initialized), FS Error (File System Error, no FAT32), No Files (no audio
files found).
In case the media contains audio material, files can be selected from the file
dialog box after a click on the arrow to the right.
Clicking on the red button will initiate recording, and a new file will be created
immediately, with an increment file number according to present files.
Info. Opens a dialog with information about the selected file: file name, number
of channels, sample rate, length (time), free memory.
Delete. Offers direct erasure of the current file. After deletion, the media is read again (Initializ-
ing) which can take some time on larger hard drives. Deleting further files is possible even while
the initialization is still in progress.
Status Panel. The overview window shows current position or length of the file, free memory,
current USB Load and Errors.
Position display. The position of the knob shows the current playback position within the file.
The knob, and with it the playback position, can also be changed by dragging it with the mouse.
Transport bar. Stop, Play/Pause and Record. Two clicks on Stop cause a jump to the beginning
of the file. Below: Previous File / Next File and Playback Modes with the options Single, UFX
single, Continuous, Single next, Repeat single, Repeat all. See next page.
