Midi Machine Control (Mmc); Using A Foot Switch; 24-Bit Operation; Monitoring System Performance - MOTU 828mkII User Manual

4 If you are using an MMC-compatible
synchronizer (such as a MOTU MIDI
Timepiece AV, Digital Timepiece or Alesis BRC),
set Cubase VST's Sync Source Timecode Base to
ASIO 2.0 MMC or enable Nuendo's MIDI Machine
Control option. In addition, choose the appropriate
MIDI port for the MMC synchronizer from VST's
Output menu or Nuendo's MIDI machine Control
MIDI Output menu. If you're using a MIDI
Timepiece AV, you can choose any of its MIDI
ports in this menu. Doing so makes Cubase or
Nuendo send the MMC control messages to the
MTP AV (or other MMC device). In this scenario,
transport control is handled by Cubase or Nuendo
itself.
5 In Cubase VST's Controls window, enable
SYNC. In Nuendo, enable (check) the Sync Online
command in the Transport menu.
Figure 11-9: Enabling the SYNC button.
6 Begin playback from the sample-accurate sync
source (ADAT, DA-88, etc.) Transport control is
handled by the sample-accurate sync source.

MIDI MACHINE CONTROL (MMC)

If you have ADATs (or other ADAT Sync-
compatible recorders) and a MMC-compatible
ADAT synchronizer like the MIDI Timepiece AV
and Digital Timepiece, you can control everything
from your computer screen with Cubase's
transport controls and cueing features (like the
playback wiper, etc.)
Similarly, if you have Tascam digital recorders and
a MOTU Digital Timepiece (or other MMC-
compatible Tascam synchronizer), you can control
all of your Tascam tape decks (in ABS time) in a
similar fashion from Cubase.
88
See "Sample-accurate sync to ADAT or Tascam" on
page 87 for details on how to set this up.

USING A FOOT SWITCH

Use a foot switch connected to the 828mkII to
trigger recording punch-in and punch-out, or any
other feature in your host audio software that is
assigned to a computer keystroke. By default, the
foot switch triggers the 3 key on the computer
keypad. To trigger a different set of keystrokes with
the foot switch, visit the MOTU FireWire Audio
Console. (See "Enable Pedal" on page 45.)

24-BIT OPERATION

Your 828mkII hardware fully supports Cubase and
Nuendo's 24-bit recording capabilities. Simply
enable 24-bit operation as instructed in your
Cubase or Nuendo manual. The 828mkII always
supplies a 24-bit data stream, and when you enable
24-bit operation in Cubase or Nuendo, it simply
uses all 24-bits supplied by the 828mkII hardware.

MONITORING SYSTEM PERFORMANCE

Because it has so many inputs and outputs, the
828mkII may push the limits of your computer's
processing power. Keep the VST Performance
window open to keep tabs on the load on your CPU
and disk buffers. If the meters get too high, you can
reduce the load by reducing the number of inputs
and outputs you are working with. Use the MOTU
FireWire Audio Console to uncheck input check
boxes and set output source menus to None.
