20.3 MIDI doesn't work
In some cases MIDI does not work after the installation of the HDSP driver. To be precise, ap-
plications do not show an installed MIDI port. The reason for this is usually visible within the
Audio MIDI Setup
. It displays no RME MIDI device, or the device is greyed out and therefore
inactive. Mostly, removing the greyed out device and searching for MIDI devices again will solve
the problem. If this does not help, we recommend manual removal of the MIDI driver and rein-
stallation of the complete driver. Otherwise repairing permissions may help.
The HDSP MIDI driver is a plugin. During installation it will be copied to
>Library/ Audio/ MIDI
Drivers<
. It's name is
HDSP MADI MIDI.plugin
. The file can be displayed in the Finder and
also be removed by simply dragging it to the trash bin.
20.4 Supported Sample Rates
RME's Mac OS X driver supports all sampling frequencies provided by the hardware. Besides
192 kHz
and
96 kHz
this also includes
32 kHz
and
64 kHz
.
But not every software will support all the hardware's sample rates. For example Spark does not
display 32 kHz and 64 kHz. The hardware's capabilities can easily be verified in the
Audio MIDI
Setup
. Select
Audio devices
under
Properties of:
and choose the Hammerfall DSP. A click on
Format
will list the supported sample frequencies.
If the unit is in clock mode
Master
, selecting a sample rate will immediately set the device to
this frequency, which can be verified in the HDSP's settings dialog (System Clock).
Format
thus
allows you to activate any sampling frequency quickly and easily.
20.5 Various Information
The driver requires 10.4.8 or higher. Older versions of OS X are not supported.
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.
Since OS X 10.3 playback can be configured freely and to any of the available playback chan-
nels. This is done via
Speaker Setup
. Even multichannel playback (Surround, DVD Player) can
be set up easily.
OS X supports more than one audio device. Since 10.4 (Tiger) Core Audio offers the function
Aggregate Devices
, which allows to combine several devices into one, so that a multi-device
operation is now possible with any software.
The Hammerfall DSP driver adds a number to each unit, so they are fully accessible in any
multicard-capable software.
