15. Mac OS X FAQ
15.1 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.
The MADIface XT USB MIDI is class compliant. Therefore it comes without a driver. OS X rec-
ognizes it as MIDI device and will be using it with the driver included in the operating system.
15.2 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.
15.3 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 MADIface XT. A
click on Format will list the supported sample frequencies.
15.4 Various Information
The driver of the MADIface XT 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 MADIface XT 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
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.
