13 Troubleshooting
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 - MOTU 8pre inputs and outputs are not
visible in Cubase
You probably need to enable them in Cubase.
Can’t authenticate AudioDesk
When installing software off the CD-ROM, 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
AudioDesk manual (on the inside of the back
cover).
Clicks and pops due to hard drive problems
If you have checked your clock settings and you are
still getting clicks and pops in your audio, you may
have a drive related problem. Set your Clock
Source to Internal and try recording just using the
analog inputs and outputs of the 8pre. If you
encounter the same artifacts you may want try
using another drive in your computer. Clicks and
pops can also occur when the drive is severely
fragmented, the disk drivers are outdated, or if you
are using a SCSI accelerator that is not optimally
configured for working with audio.
Connecting or powering gear during operation
It is not recommended that you connect/
disconnect, or power on/off devices connected to
the 8pre while recording or playing back audio.
Doing so may cause a brief glitch in the audio.
No optical inputs or outputs are available in host
audio application
Check to make sure you have the desired optical
inputs and/or outputs enabled in MOTU Audio
Setup.
Monitoring - How to monitor inputs?
Please refer to the documentation for the audio
application that you are using. If your application
does not support input monitoring, you will need
to use the 8pre’s hardware-based CueMix DSP
monitoring feature. Please see chapter 10,
“Reducing Monitoring Latency” (page 45).
Controlling monitoring latency
See chapter 10, “Reducing Monitoring Latency”
(page 45).
