15.5 Various Information

The current driver of the Fireface requires at least Mac OS 10.6.

Programs that don't support card or channel selection will use the device chosen as Input and

Output in the System Preferences – Sound panel.

Via Launchpad – Other – Audio MIDI Setup the Fireface can be configured for the system

wide usage in more detail.

Programs that don't support channel selection will always use channels 1/2, the first stereo pair.

To access other inputs, use the following workaround with TotalMix: route the desired input

signal to output channels 1/2. In the channel settings of outputs 1/2 activate Loopback. Result:

the desired input signal is now available at input channel 1/2, without further delay/latency.

Use Configure Speakers to freely configure the stereo or multichannel playback to any avail-

able channels.

16. Using more than one Fireface

OS X supports the usage of more than one audio device within a audio software. This is done

via the Core Audio function Aggregate Devices, which combines several devices into one.

The current driver supports up to three Fireface UCX. All units have to be in sync, i.e. have to

receive valid sync information either via word clock or by feeding synchronized signals.

• If one of the Firefaces is set to clock mode Master, all others have to be set to clock mode

Slave, and have to be synced from the master, for example by feeding word clock. The

clock modes of all units have to be set up correctly in the Fireface Settings dialog.

• If all units are fed with a synchronous clock, i.e. all units show Sync in their Settings dialog,

all channels can be used at once.

When using more than one Fireface UCX the USB/FW bus might get overloaded. To prevent

this connect all units to different busses. See chapter 37.3 and 37.4 for further notes on USB

and FireWire performance.

Note

: TotalMix is part of the hardware of each Fireface. Up to three mixers are available, but

these are separated and can't interchange data. Therefore a global mixer for all units is not

possible.
