31.2 Class Compliant Mode under Windows and Mac OS X
On a Windows PC, Class Compliant mode is indicated by a missing “RME“ in the device name
shown in the Device Manager. In the correct mode and with installed drivers, the full name in-
cluding RME is shown, without serial number. In real-world this case should never come up as
TotalMix FX resets the unit to normal mode whenever it detects CC mode.
This is also true for Mac OS X. Here the Fireface 802 would in principle work in CC mode, as
MAC OS X supports USB audio 2.0, even with more than 2 channels. Still there would be no
hardware control and no mixer control, so operating it that way does not make sense.
Alsa (Linux) does not work with USB 2 Class Compliant interfaces at this time, but it seems it
can be fixed (recompiled) to do so. More information is available here:

32. Supported Inputs and Outputs
When connected to an iPad, the analog mic/line input 1 works with mono apps, inputs 1 and 2
with stereo apps (both dual mono and stereo), and up to 8 inputs with 8-channel applications
like
MultiTrack DAW
and
Music Studio
.
Garage Band
supports all inputs, but only two at a time.
Auria
and
Cubasis
can record all 22 inputs of the Fireface 802 simultaneously.
Playback will use the rear-side analog outputs 1 and 2, or even more channels if the app sup-
ports such operation.
Configuring the 802 is ideally done via the app
TotalMix FX for iPad
, otherwise by loading Set-
ups. These are written into the unit while operated with PC/Mac via TotalMix FX, and also con-
trol clock mode master or AutoSync and the sample rate. The 802 (and with it the iPhone/iPad)
will be synchronized to an external digital sample rate if there is a valid digital input signal. With
a wrong sample rate heavy audio noise will occur. Without an SPDIF or ADAT input signal the
802 enters master mode and uses the sample rate set by iOS (the app in use).
While the MIDI I/Os will send and receive Sysex messages, not all apps are ready to do this.
For example
MIDI Monitor
and
AC-7
do not support Sysex at this time. The app
Midi Tool Box
can be used to verify that the 802 is working correctly, and the problem lies somewhere else.
33. Front panel operation
The front panel operation is identical to the one under Windows and OS X or stand-alone. It is
limited to the direct access on Gains and Volume, and the functions enabled by the ARC.
