19. Mac OS X FAQ

19.1 MIDI doesn't work

In some cases the applications do not show the MIDI port. The reason for this is usually visible

within the Audio MIDI Setup – MIDI Window. 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.

The HDSPe MIDI driver is a plugin. During installation it will be copied to >Library/ Audio/ MIDI

Drivers<. Its name is HDSPe FX MIDI.plugin. The file can be displayed in the Finder and also

be removed by simply dragging it to the trash bin.

19.2 Repairing Disk Permissions

Repairing permission can solve problems with the installation process - plus many others. To do

this, launch Disk Utility located in Utilities. Select your system drive in the drive/volume list to

the left. The First Aid tab to the right now allows you to check and repair disk permissions.

19.3 Supported Sample Rates

RME's Mac OS X driver supports all sampling frequencies provided by the hardware. This in-

cludes 32 kHz and 64 kHz, and even 128 kHz, 176.4 kHz and 192 kHz.

But not any software will support all the hardware's sample rates. The hardware's capabilities

can easily be verified in the Audio MIDI Setup – Audio Window. Select the HDSPe MADI FX.

A click on Format will list the supported sample frequencies.

19.4 Various Information

The driver of the HDSPe MADI FX requires 10.6 or higher.

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 MADI FX 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.
