Chasing MIDI Time Code
With snapshots enabled for automated recall, the Chase MTC
function needs to be engaged to allow automated recall to oc-
cur.
To initiate automated recall of snapshots:
1 Click the Chase MTC button so that it is highlighted.
2 Begin MTC playback by starting the internal generator (if set
to MTC Generate) or the external device (if set to MTC Read).
When a recall-enabled snapshot’s time code value is reached,
the snapshot is recalled.
The Chase MTC button can be used to quickly take D-Show
offline from MTC-triggered recall in performance in the event
of a change in timing, such as a missed cue or dropped verse.
You can then advance manually to an appropriate snapshot,
and re-enable Chase MTC.
Remote Control of Snapshot Recall
D-Show can be set to recall snapshots in response to MIDI
control messages sent from an external device such as an AV
controller system. You can set the system to respond to con-
trol messages sent on any one of 16 available MIDI channels.
Snapshots are recalled when their snapshot number (1–999) is
received in the form of MIDI Bank Select and Program Change
messages. (See Table 23 on page 175.)
To enable recall of snapshots from an external device:
1 Go to the Options page and click the Snapshots tab.
2 Under MIDI, select the “Snapshots Respond to Channel”
option, and choose the MIDI channel from the corresponding
pop-up menu.
D-Show listens on the specified channel for Bank Select and
Program Change messages.
D-Show does not chase up to the current timecode value. If
you start playback in the middle of a snapshot sequence,
any prior snapshots will need to be recalled manually to
update the console before beginning time code playback.
Snapshot MIDI respond option
The MIDI Snapshot Output Safe option does not affect this
option. You can only turn off this feature by deselecting the
“Snapshots Respond to Channel” option.
Table 23. MIDI Bank and Program Numbers for Snapshots
Bank Program Snapshot Number
0 0–127 001–128
1 0–127 129–256
2 0–127 257–384
3 0–127 385–512
4 0–127 513–640
5 0–127 641–768
6 0–127 769–896
7 0–103 897–999
D-Show stores Bank Select messages, so it is not necessary
to send a Bank Select message prior to every Program
Change message. You only need to send a Bank Select
message when you want to recall a snapshot in a different
bank from the previous snapshot.
