24—MIDI and Synchronization
Roland VS-2480 Owner’s Manual www.rolandus.com 317
You can shift, or “offset,” the project’s start time to solve this problem so that whenever
the master starts over, your project begins at the top. To offset the project start time:
1. Press UTILITY.
2. If “Proj” isn’t visible above F3, press PAGE until it is.
3. Press F3 (Proj).
The DISPLAY OFFSET TIME parameter shifts the
project’s start time. To find the value you want,
subtract the desired project start time—typically
00h00m00s00f00—from the master’s start time. Enter
this amount as the DISPLAY OFFSET TIME.
4. Set the TIME DISPLAY FORMAT parameter to REL, for “Relative Time,” so that the
current time location display shows the project’s shifted start time instead of ABS
(absolute) MTC/SMPTE time during playback.
Starting Synchronized Playback with the VS-2480 as Slave
1. On the VS-2480, if the EXT SYNC indicator isn’t already flashing, press it
so that it is—this is the same thing as setting the SYNC MODE
parameter to EXT (Page 315).
2. Press PLAY on the VS-2480—its indicator flashes green to indicate that it’s awaiting
external time code.
3. Start playback on the master device—the VS-2480 begins playback as well. If you’ve
shifted the project’s start time, the VS-2480’s timeline jumps to the desired location.
4. To halt playback, stop playback on the master. If you’ve shifted the project start
time, the VS-2480’s timeline jumps to its actual MTC/SMPTE time code location
when playback stops.
Exchanging Digital Audio Data During Synchronization
You can exchange digital audio between the VS-2480 and its sync partner. You might, for
example, want to move audio tracks from one V-Studio to another. To learn about digital
connectors, see Page 49. To learn about clocking digital audio, see Page 132.
When the VS-2480 is the Master
You can set its MASTER CLOCK parameter (Page 132) to INT to send digital audio to
the slave device with the VS-2480 controlling the audio’s timing.
When the VS-2480 is the Slave
You can receive digital audio from the master device by setting the VS-2480’s MASTER
CLOCK to EXT TIME CODE. The received digital audio’s clocking is computed from,
and controlled by, the master device’s time code.
You can also send digital audio from the VS-2480 to the master device by setting the
VS-2480’s MASTER CLOCK parameter to INT—with this setting, the VS-2480
generates its own master clock based on the time code received from the master device.
This formula is especially helpful if your project’s audio starts somewhere other than
zero. Use the location at which the audio begins as your desired start time. If you get a
negative result, add 24.00.00.00.00 to the master’s start time and do the math again.
Sync-related parameters can’t be adjusted while the PLAY indicator is flashing.
