D-Show Profile Guide 212
Triggering of External Devices on
Snapshot Recall
D-Show can be set to send MIDI Bank and Program Change
messages whenever a snapshot is recalled, to trigger external
devices whose cues are related to snapshots. You can set the
system to send on any one of 16 available MIDI channels.
While it is possible to add Bank Select and Program Change
messages to individual snapshots, this option lets you toggle
messages on and off for all snapshots in one step. Using this
option also ensures that the Bank Select and Program Change
messages correspond to the snapshot number, even after
snapshots are rearranged in the Snapshots list.
The Bank Select and Program Changes messages reflect the
number (1–999) of the recalled snapshot. (See Table 24 on
page 211.)
To enable triggering of external devices when snapshots are
recalled:
1
Go to the Options page and click the Snapshots tab.
2
Under MIDI, select the “Snapshots Send on Channel” op-
tion, and choose the MIDI channel from the corresponding
pop-up menu.
D-Show sends a Bank Select and Program Change message on
the specified channel whenever a snapshot is recalled.
Sending MIDI Messages on Snapshot
Recall
You can add up to 20 specific MIDI messages to each snap-
shot. These messages are sent whenever the snapshot is re-
called. Sending of the messages is enabled with the MIDI
scope control in the Snapshots window. For more informa-
tion, see Chapter 21, “Snapshots.”
Synchronizing with Word Clock and
Digital Audio Input
D-Show receives and outputs Word Clock (at a sample rate of
48 kHz ± 10ppm) for synchronization with a master clock
generator (house sync) or other device that uses clock refer-
ence. D-Show can operate as a Word Clock master, or it can
slave to Work Clock input.
The Word Clock In and Word Clock Out ports are located on
the back panel of the FOH Rack. Additional Word Clock op-
tions are available on systems that include a DSI card (Digital
Stage Input) in the Stage Rack.
Synchronizing with Digital Audio Input
D-Show automatically synchronizes to the signal on any of its
digital inputs, performing sample rate conversion as necessary
to the D-Show native sample rate of 48 kHz.
This lets you connect a variety of digital sources (such as a
DAT machine or CD player with digital outputs), directly to
D-Show.
For instructions on Word Clock and digital audio connections
for synchronization, see Chapter 2, “Configuring and Con-
necting D-Show.”
MIDI output is automatically suspended while in Preview
mode. For more information, see “Preview Mode” on
page 185.
D-Show always sends a Bank Select message before every
Program Change message, even if the bank number has not
changed from the previous snapshot.
Snapshot MIDI send option
The MIDI Snapshot Output Safe command does not affect
the option to send on specific MIDI channels. You can only
turn off this feature by deselecting the “Snapshots Send on
Channel” option.
