About Show Control

The Ion Show Control system consists of MIDI Show Control plus any number of time code event

lists (MIDI or SMPTE). There can be more than one event list of each type, but only one MIDI Show

Control is available. For instance there can be multiple SMPTE Time Code lists, each with its own

timing source, frame rate and event list. All can be running simultaneously.

Each event list has a label, data source and status. The status information depends on the list type

and is detailed below.

Setup

Ion provides user-definable settings for show control which can be accessed by pressing

[Displays]>{Setup}>{Show}>{Show Control}. For more information, see Show Control, page 83.

MIDI Show Control

Data Sources

MIDI Show Control (MSC) receives data from a MIDI input source. There are 32 available MIDI

sources, numbered 1-32. MIDI consists of many types of data, but MSC looks only at MSC data.

Other MIDI transmitted data is ignored by MSC.

MIDI Show Control Devices

MIDI Show Control data carries a device ID within the data packet. MSC setup allows for the

specification of two device IDs: one for reception and one for transmission.

Only MSC data with the correct receive device ID, or an ALL CALL ID, will be interpreted by Ion.

All outgoing MSC data contains the specified transmit device ID within.

Ion Command Interpretation

When Ion receives a command from a MIDI source, it will look for and support the following MIDI

commands in the following ways:

• Go Runs a cue

• Stop Pauses a Cue

• Resume Resumes a paused cue

• Set Controls a submaster, playback, or grandmaster

• Fire Runs a macro

The cue-related commands (go, stop, resume) affect Ion based on the cue and list fields also

contained within the MSC data. Cue and list fields will correspond directly to the Ion cues and cue

lists. In the command/effect tables below, if a field is present in the MSC data, the name is indicated

(such as “Cue” or “List”). If it is not present in the data, a “-” is indicated. For example, “Cue -”

implies that a cue is specified in the data, but not a list.
