Vista 1 Digital Mixing System
MIDI/MMC Events
The MIDI/MMC (MIDI machine control) event type can either be used for
automatically sending MIDI commands if the symbol has been entered into
the Events column (such as Program, Note On, Controller, MMC and Sysex),
or for triggering the associated cue on arrival of the command if the symbol
has been entered into the  column (such as Program, Note On or Control-
ler).
MMC commands are a subset of the MIDI Sysex ('system exclusive') com-
mand set that are used for triggering transport commands for external play-
back equipment, such as Stop, Play, Locate, etc.; 'Deferred Play' is a Play
command that is executed after the playback transport has found the desired
cue position.
A MIDI event is entered either by dragging it from the Events area and drop-
ping it into the Events column of the selected cue, or by a right-click into
the Events column of the selected cue and selecting the desired event from
the dropdown list. It can be configured in the Configuration area, or deleted
if highlighted by a click and either pressing Del on the keyboard or clicking
on the Cue Delete button.
If MIDI input control signals are used, a MIDI event symbol is inserted into
the  column of the cue list, either by dragging-and-dropping it from the
Configuration area or just by double-clicking into the desired cue list cell.
For deleting it, either highlight it with a click and press Del on the keyboard
or click on the Cue Delete button. It can also be deleted from the cue list
with a double click.
In order to avoid undesired influence by external devices, the ARM CUELIST
button is used to arm/disarm the cue list inputs. If not armed, the blackout
function, MIDI In events, as well as the hardware NEXT and PREVIOUS
keys on the console surface are disabled. Different options for this button can
be set in the Snapshot/Snapshot Automation Options menu.
