+====== RME Babyface ======
+===== General =====
+{{ http://www.rme-audio.de/images/products/rme_babyface_1.jpg}}
+The [[http://www.rme-audio.de/en_products_babyface.php|RME Babyface]] is an USB 2.0 interface with:
+  * 10 Input / 12 Output channels
+  * 2 x Analog Input
+  * 4 x Analog Output
+  * 1 x ADAT I/O or 1 x SPDIF I/O optical
+  * 1 x MIDI I/O
+  * 1 x USB 2.0
+  * 2 x Mic Preamp with digitally controlled gain
+  * 1 x Hi-Z instrument input
+  * TotalMix FX (with EQ via internal DSP, Reverb, Echo).
+===== Support =====
+Class compliant via new firmware (version 200). In CC (Class Compliant) mode the Babyface should work out of the box without having to use a patched kernel. This is contrary to the Fireface UCX, with which the Babyface shares its internals, which does need a patch ((https://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28901.html)).
+When plugged in ALSA should recognize the Babyface as follows with a 3.2 kernel:
+  $ cat /proc/asound/cards | grep -i baby
+[B23596862      ]: USB-Audio - Babyface (23596862)
+                       RME Babyface (23596862) at usb-0000:00:1d.7-6, high speed
+And with a 3.8 kernel:
+  $ cat /proc/asound/cards | grep -i baby
+[Babyface2359686]: USB-Audio - Babyface (23596862)
+                       RME Babyface (23596862) at usb-0000:00:14.0-2, high speed
+===== JACK Settings =====
+According to the RME site:
+>"//The Babyface achieves latency values down to 48 samples on Windows and 14 samples on Mac OS X.//((http://www.rme-audio.de/en_products_babyface.php#4))
+On Linux the Babyface runs well at 32 samples:
+  /usr/bin/jackd -P79 -t2000 -dalsa -dhw:B23596862 -r48000 -p32 -n2 -s
+Using lower periods settings is possible too, the device starts and runs when using 8 samples for example but basically anything below 64 samples is not very usable because you quickly run into buffer issues (xruns). Linux does beat the other two OS's though when it comes to low latency values.
+==== TotalMix FX and DSP ====
+TotalMix and the internal DSP can't be used in CC (Class Compliant) mode so these options are not available when using the Babyface with Linux.
+==== Switching to Class Compliant mode ====
+Hold down the Select and Recall buttons simultaneously while connecting the Babyface to an USB port. If the level meters run up the interface is in CC mode. Repeating this procedure will put the interface back in normal mode again. In normal mode only one LED of each meter will light up when powering on the Babyface. When in normal mode the interface won't be recognized on a Linux system.
