MIDI Machine Control
OVERVIEW
As a synchronization hub for your studio, the
Digital Timepiece has the ability to be remotely
controlled from any device — or computer
software — that supports MIDI Machine Control.
This capability allows you to locate, play, record,
stop and cue everything from one master set of
transport controls. For example, you could control
everything from digital audio workstation software
on your computer. Or you could control
everything from a hardware MMC control surface,
such as a JL Cooper CuePoint™.
Depending on what gear you have, you can even do
both at the same time. For example, you could set
up your computer software as one transport
control master, and a hardware MMC controller
connected via MIDI as another.

HOW MMC WORKS
MIDI Machine Control involves all three
components of synchronization:
■
time base
■
address
■
transport control
An MMC controller (which has tape deck-style
transport controls) sends transport commands
(play, stop, locate, etc.) to another MMC device
that serves as the address (time code) master.
When the address master device responds to the
transport commands, it generates time code to
which all other devices chase and lock. The other
devices do not need to be MMC devices; all they
have to be able to do is slave to time code (LTC or
MTC) in the usual fashion.
The MMC address master device may also serve as
the time base master, but it doesn’t necessarily have
to. For example, video house sync could provide
the time base, while the Digital Timepiece provides
address.
Figure 8-1: An example scenario for MMC control of your Digital
Timepiece studio. Digital Performer (or any MMC-compatible
software) sends MMC transport commands (play, stop, record, locate,
etc.) to the Digital Timepiece, which responds to them by generating
time code and, in some cases, redistributing the MMC commands (to
devices like ADATs, DA-88s and SONY 9-pin decks).
A RECOMMENDED SCENARIO FOR MMC
You should try, if you can, to set up your rig so that
the Digital Timepiece is the address master (by
choosing one of its
Internal
modes). You can then
control it (and everything connected to it) directly
