19.5 Various Information
The driver requires 10.5.8 or higher.
Via
>System Preferences/ Audio-MIDI Setup<
the hardware can be configured for the system
wide usage. Programs that don't support card or channel selection will use the device selected
as
Standard-Input
and
Standard-Output
. (Soundstudio, Mplayer, Amplitube etc.).
In the lower part of the window, the audio hardware's capabilities are shown and can be
changed in some cases. On the record side no changes are possible. Programs that don't sup-
port 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. Hold the Ctrl key down and click on the labels AN1 and AN2 in the third row. Their labels
turn red, the internal loop mode is active. Result: the desired input signal is now available at
input channel 1/2, without further delay/latency.
Use
Speaker Setup
to freely configure the playback to all available channels. Even multichan-
nel playback (Surround, DVD Player) can be set up this way.
20. Using more than one HDSPe System
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.
The current driver supports up to three HDSPe in any combination. All units have to be in sync,
i.e. have to receive valid sync information either via word clock or by feeding synchronized sig-
nals.
•
If one of the units 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 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.
Note: TotalMix is part of the hardware of each HDSPe system. 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.
