8. Operation and Usage
8.1 Playback
The MADIface XT can play back audio data in supported formats only (sample rate, bit resolu-
tion). Otherwise an error message appears (for example at 22 kHz and 8 bit).
In the audio application being used, the XT must be selected as output device. This can often
be found in the
Options, Preferences
or
Settings
menus under
Playback Device, Audio Devices,
Audio
etc.
We strongly recommend switching off all system sounds (via >
Control Panel /Sounds
<). Also
MADIface should not be the
Preferred Device
for playback, as this could cause loss of synchro-
nization and unwanted noises. If you feel you cannot do without system sounds, you should use
on-board sound or any cheap sound card and select this one as
Preferred Device
in >
Control
Panel /Multimedia /Audio
< or >
Control Panel /Sound /Playback
<.
The screenshot to the
right shows a typical
configuration dialog as
displayed by a (stereo)
wave editor. After
selecting a playback
device, audio data is
sent to the according
channels.
Increasing the number
and/or size of audio
buffers may prevent the
audio signal from
breaking up, but also
increases latency i.e.
output is delayed. For
synchronized playback
of audio and MIDI (or
similar), be sure to
activate the checkbox
‘Get position from audio
driver’.
The MADIface XT allows sample rates of up to 192 kHz via MADI. In this mode, only 16 chan-
nels are functional per MADI port.
Note on Windows Vista/7/8:
Since Vista the audio application can no longer control the sample rate under WDM. Therefore
the driver of the MADIface XT includes a workaround: the sample rate can be set globally for all
WDM devices within the Settings dialog, see chapter 7.1.
