23—MIDI and Synchronization
The VS-2400CD can transmit this form of synchronization as a:

The primary difference between a sync track and a tempo map in synchronization
operations is that a tempo map lets you see and edit tempo and time signature changes.
A project's tempo map also provides the basis for the Home screen's track editing grid.
To synchronize an external MIDI device to the VS-2400CD using a sync track or tempo
map, the device must recognize MIDI clock and Song Position Pointer messages.
The VS-2400CD has an area of memory set aside for a sync track—it isn't recorded on a
project track and doesn't take up any recording tracks.
It's important to understand that a sync track or a tempo map has no effect on the
speed at which a project plays back—this speed is determined by the project's
sampling rate and its VARI PITCH setting, or by received MTC/SMPTE time code. A
sync track and tempo map merely transmit tempo and time signature information that
describes what's going on in a project to a MIDI device synchronized to the VS-2400CD.
The SYNC PARAMETER Screen
1. To set up synchronization, hold down SHIFT and press F4•UTILITY.
2. If "SYNC" isn't visible above F6, press PAGE until it is.
3. Press F6 (SYNC)—the SYNC PARAMETER screen appears.
4. Select the desired sync parameter and adjust its value.
Some synchronization operations also involve parameters on the MIDI PARAMETER
screen (Page 285).

sync track—a single, uneditable stream of MIDI clock/SPP synchronization data.
The VS-2400CD can record a sync track comprised of captured MIDI clock and
Song Position Pointer data received from an external MIDI device. This lets an
external sequencer "teach" the VS-2400CD a song's tempo and time signature
changes. The data can then be sent back to the sequencer, slaving it to the
VS-2400CD. You can also construct a sync track for a new or already recorded
project using markers. In addition, the VS-2400CD can use information you provide
about an already recorded project to create a new sync track. See Page 297.
tempo map—an editable stream of MIDI clock/SPP synchronization data. Each
VS-2400CD project has its own a tempo map in which you can view and edit a
project's tempo and time signature changes. You can build a tempo map for a new
or already recorded project on the VS-2400CD manually or by using markers, or
convert an existing sync track into a tempo map. For details, see Page 298.
