Troubleshooting
Using Pro Tools, Sound Manager and -50 error
When using Sound Manager, Pro Tools software
will only allow audio input via the Macintosh's
Built-in hardware. Therefore, you cannot use the
PCI-424 system as the input device to Pro Tools
software. If the PCI-424 Driver is selected as the
input device in the Sound Control Panel, Pro Tools
will return a -50 error and not launch. You can,
however, select Built-in as the input device and the
PCI-424 Sound Manager Driver as the output
device in the Sound Control Panel. After doing so,
you can run Pro Tools and monitor your output
through the PCI-424 system.
My host software doesn’t receive any audio from an
input; other inputs are working fine, but this one
input isn’t.
Open CueMix Console and make sure that the
input isn’t globally muted (the mute button at the
very top of the channel strip, below the message
center).
Sample accurate sync in AudioDesk and Digital
Performer
When you first use sample accurate sync, be sure to
go to the Receive Sync dialog in Digital Performer
or AudioDesk and switch from “MTC” to “Sample-
accurate.”
Cubase - Inputs and outputs are enabled in the
MOTU PCI Audio Console, but still not visible in
Cubase
This would indicate that you do not have these
inputs enabled in Cubase. Select Inputs from the
Audio menu. Make sure that the inputs are
enabled.
Monitoring input sources via the PCI-424 Sound
Manager driver
With the PCI-424 system, monitoring input
sources via the Sound Manager Driver takes place
at the hardware level. Be sure the PCI-424 Sound
Manager Driver is chosen in the Sound Control
Panel for input and output. If you enable
Monitoring in a Sound Manager application like
PEAK 2.0, you must also set the level for the output
pair using the PCI-424 CueMix Console.
Can’t authenticate AudioDesk
When installing software off the CD, the OK
button does not become active until you have
entered in your name and a valid keycode. Your
name must contain at least 3 characters, and you
must enter the keycode exactly as it appears in your
users manual.
MOTU PCI Audio Console - Error: The PCI-424
driver can not be accessed at this time because it is
currently in use
This error is caused when another application is
using the PCI-424 driver at the while you attempt
to configure your MOTU Audio interface via the
MOTU PCI Audio Console. While the PCI-424
driver is a multi-client driver and several
applications can access the driver at once, you
cannot configure the driver while it is in use by
another application. If you have the PCI-424
Sound Manager driver enabled for Sound In and
Sound Out, and there no applications running
besides Digital Performer or Audio Desk, it is likely
that an extension may be claiming the Sound
Manager driver when the computer boots up. The
solution: Disable the extension or choose Built-In
for both Sound In and Sound Out in the Sound
Control Panel.
