Using The Sync Track - Roland VXpanded VS-880 Owner's Manual

Gen (Sync generator)
This selects the type of synchronization signal that will be
transmitted from the MIDI OUT connector. When using a
synchronization signal from the VS-880 to synchronize
external MIDI devices, set this to the desired type of syn-
chronization signal.
Off: Synchronization signals will not be transmit-
ted.
MTC: MIDI Time Code will be transmitted.
MIDIClk: MIDI Clock will be transmitted.
SyncTr: MIDI Clock data recorded on the sync track
will be transmitted.
Changing the tempo during the per-
formance
To modify tempo map settings, use the following proce-
dure.
< Limitations on changing the starting measure >
Tempo maps are numbered from the beginning of the
song as tempo map 1, tempo map 2, tempo map 3, etc.
This means that it is not possible to modify the starting
measure of a tempo map to make it earlier than the start-
ing measure of the previous tempo map, or later than the
starting measure of the following tempo map. For exam-
ple if tempo map 2 has a starting measure of Ò8Ó and
tempo map 4 has a starting measure of Ò16,Ó the starting
measure of tempo map 3 can be modified only in the
range of Ò9Ð15.Ó
1. Press [SYSTEM].
If a message with a question mark such as ÒSYS System
PRM?Ó does not appear, press [SYSTEM] once again.
2. Use PARAMETER [
Sync/tempo?" display, and press [YES].
3. Use PARAMETER [
Tmap1=" display, and use the TIME/VALUE dial to
select the tempo map that you wish to change.
4. Press CURSOR [
] to make the blinking area to the
item (tempo, starting measure, time signature) that you
wish to change, and use the TIME/VALUE dial to modi-
fy the value.
* Since tempo map 1 is the initial tempo of the song, it is
not possible to modify the starting measure setting of Ò1.Ó
5. When you finish making settings, press CURSOR [
to make the tempo map number blink, and press [PLAY
(DISPLAY)] to return to Play condition.

Using the sync track

In this section, the method of using the sync track is
explained.
In addition to the tracks for recording audio signals, the VS-
880 has a separate sync track for recording MIDI Clock sig-
nals. This means that unlike conventional analog multitrack
recorders, it is not necessary to reserve one of the audio
tracks for recording the sync signal.
To use the sync track, the MIDI clock of the MIDI song data
to which you want to synchronize must first be recorded
onto the sync track. Then, transmit the recorded MIDI clock
data to the MIDI sequencer to synchronize the MIDI song
data. In this way, while the method of using the tempo map
explained in the previous section synchronizes the perfor-
mance to the VS-880 song, this method of using the sync
track synchronizes the performance to the MIDI song data.
Thus, this is a convenient method to use when the MIDI
song data has been created earlier than the VS-880 song.
In particular, when synchronizing to MIDI song data in
which the tempo gradually becomes faster or slower, using
the tempo map allows more precise following of tempo
changes, compared to the tempo map in which tempo is set
for each measure.
< Notice for synchronization >
The MIDI clock data recorded in the sync track is trans-
mitted after song playback or recording begins. This
means that if the music begins at the moment that play-
back begins, the MIDI sequencer will have to start playing
back the MIDI song data at the same time that it receives
the first MIDI clock data. In some cases, this can cause
synchronization to be initially unstable.
If this problem occurs, insert several measures of blank
space at the beginning of the VS-880 song and the MIDI
sequencer song.
