Roland Vs-880 Using the sync track, Changing the tempo during the per- formance, Chapter

Chapter 5 Use with MIDI devices

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 [ ][ ] to get the “SYS Sync/tempo?” display, and press [YES].

3.Use PARAMETER [ ][ ] to get the “SYS Syn: 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

■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.
