Although Ghost allows automation of mute snapshots via its own internal CPU, full
real-time dynamic automation of individual mutes requires the use of an external
MIDI sequencer to act as the recording and storage device.
Ghost has been designed to allow each mute switch to transmit MIDI data in the
form of note-on messages, which can be recorded on a dedicated track in the
sequencer alongside (and therefore synchronised to) normal music tracks. On
playback of the sequence, Ghost will receive the note data and will convert it back
to individual mute events.

There are a number of things to bear in mind when using the console with a
sequencer in this way:
l Ghost transmits a note-on with velocity of 1 when a channel is muted, and
a note-on with velocity of 127 when the channel is unmuted.
l Each channel and mix-B mute switch sends its own unique note number,
which will be in the range 0-63 (or 0-111 if you have the 24 Channel
Expander option).
l Ghost automatically transmits a snapshot of the current status of all mute
switches, when the PLAY transport button is pressed. The sequencer must
record this snapshot at the beginning of a new mix, to ensure that it can ini-
tialise Ghost's mutes correctly on playback. This snapshot consists of a
burst of note-on data corresponding to the initial mute status.
l The note-on MIDI messages are transmitted and received on the consoles
Global MIDI channel (the same channel is also used for sending and receiv-
ing program changes).

Press the DISPLAY MODE button (6) repeatedly until the Setup LED next to
the switch is illuminated. This switches Ghost's timecode display to show setup
parameters, instead of timecode.
Press the UP/DOWN buttons (4) repeatedly until the three digits on the right
hand side of the display (labelled SNAPSHOT NUMBER) start to flash.
Turn the Jog Wheel (2) in either direction until the flashing Snapshot Number dis-
plays the letters "GLO".
Notice that as the Jog Wheel is turned clockwise, the number in the display is changed
through the range 1, 2, 4, 5, ....128, ALL, GLO, then repeated. Turning anticlockwise
changes the numbers in the reverse direction.
The console is now in "Global Setup" mode.
To select the required Global MIDI channel, press the DOWN button three
times, which will select the Midi Chan field in the display, and it will start flashing.
If the Midi Chan field does not flash, continue to press the UP or DOWN but-
tons until it is flashing.
