15.5 Various Information
The driver requires 10.9 or higher. Older versions of OS X are not supported.
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 HDSPe MADI can be configured for the sys-
tem 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 sig-
nal 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 availa-
ble channels.
16. Using more than one HDSPe MADI
OS X supports the usage of more than one audio device within an audio software. This is done
via the Core Audio function Aggregate Devices, which allows to combine several devices into
one. 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 HDSPe 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, AES or SPDIF.
The clock modes of all units have to be set up correctly in their Settings dialogs.
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 resides inside the hardware of the respective card. Up to three mixers are availa-
ble, but these are separated and can't interchange data. Therefore a global mixer for all units is
not possible.
