Choosing The Motu Firewire Asio Driver - MOTU 828mkII User Manual

Clock Source
This setting is very important because it
determines which audio clock the 828mkII will
follow.
If you do not have any digital audio connections to
your 828mkII (you are using the analog inputs and
outputs only), and you will not be slaving Cubase
to external SMPTE time code, choose Internal.
If you are slaving the 828mkII to the ADAT sync
Input connector, choose ADAT 9-pin.
If you are slaving the 828mkII and Cubase to
SMPTE time code via the 828mkII itself, choose
SMPTE and follow the directions in "Syncing to
SMPTE time code" on page 27.
☛
If you are using an ASIO host application
other than Cubase or Nuendo, it must support the
ASIO 2.0 sample-accurate positioning protocol in
order to support the 828mkII's direct SMPTE sync
(and sample-accurate sync) feature.
If you have digital audio devices connected to the
828mkII, or if you are not sure about the clock
source of your setup, be sure to read "Making sync
connections" on page 22 and "Clock Source" on
page 42.
Samples Per Buffer
The Samples Per Buffer setting can be used to
reduce the delay — or monitoring latency — that
you hear when live audio is patched through your
828mkII hardware and Cubase. For example, you
might have MIDI instruments, samplers,
microphones, and so on connected to the analog
inputs of the 828mkII. If so, you will often be
mixing their live input with audio material
recorded in Cubase. See chapter 12, "Reducing
Monitoring Latency" (page 89) for complete
details.

Optical input and output
To make a 828mkII optical input or output
available in Cubase, choose the appropriate format
(ADAT optical or TOSLink) from the optical input
and/or output menu. If you won't be using the
optical connectors, turn them off.
Phones
This 828mkII setting lets you choose what you'll
hear from the headphone jack. For example, if you
choose Main Outs, the headphones will duplicate
the main outs. Or you can choose any other output
pair. If you choose Phones, this setting makes the
headphone jack serve as its own independent
output pair. As a result, you'll see Phones 1-2 as an
additional audio destination in Cubase's audio
output menus.
CHOOSING THE MOTU FIREWIRE ASIO
DRIVER
Once you've made the preparations described so
far in this chapter, you're ready to run your audio
software and enable the MOTU FireWire ASIO
driver. Check the audio system or audio hardware
configuration window in your software. There will
be a menu there that lets you choose among
various ASIO drivers that may be in your system.
Choose the MOTU FireWire ASIO driver from this
menu.
Cubase VST
To activate the 828mkII driver in Cubase VST,
choose Audio Setup>System from the Options
menu, and then choose MOTU FireWire from the
ASIO device menu. Make the other settings in the
dialog as need for your system and synchroni-
zation scenario.
Nuendo
To activate the 828mkII driver in Nuendo, go to the
Device Setup window, click VST Multitrack and
choose MOTU FireWire ASIO from the ASIO
