14.3 Channel Count under Core Audio

In Single Speed Speed (44.1 and 48 kHz) 64 + 64 input and output channels each are

available. Double Speed (88.2 and 96kHz) reduces the number of available channels to 32

each. Quad Speed (176.4 and 192kHz) reduces the number of available channels to 16 each.

It is not possible to change the number of Core Audio devices without a reboot of the computer.

So when the Digiface Dante changes to Double Speed (88.2/96 kHz) or Quad Speed mode

(176.4/192 kHz) all channels stay present, but are partly inactive.

14.4 Various Information

The driver of the Digiface Dante requires at least Mac OS 11.

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 MADIface 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.

15. Using more than one Interface

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

via the Core Audio function Aggregate Devices, which allows to combine several devices into

one. This function is found in the Audio MIDI Setup – Audio Window. Click the + sign in the

lower left.

The current driver supports up to three RME USB devices of the MADIface series. All units

have to be in sync, i.e. have to receive valid sync information (by feeding synchronized signals).

x If the Digiface Dante is set to clock mode Master (Internal), all others have to be set to clock

mode Slave, and have to be synced from the master. The clock modes of all units have to

be set up correctly in the MADIface Settings dialog.

x 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.

Note

: TotalMix is part of the hardware of each unit. 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.

Using more than one Digiface Dante is currently not supported.
