13.2.3 MIDI Time Code
MIDI time code is used to synchronise Script Files with an external
music track.
Quarter-frame message types are fully supported and these follow the
standard format, which can be found in most MIDI handbooks. A
suitable EBU/LTC Timecode to Midi Timecode converter is manufactured
by JC Cooper Electronics whose address is 12500 Beatrice Street, Los
Angeles CA 90066 USA, or through Avolites UK.
13.2.4 MIDI Problems
The console supports a full MIDI data rate burst for 2 seconds, after
that data may be lost since it cannot be processed.
A MIDI debug Terminal is available which shows you the MIDI
commands being received by the Pearl. To activate this :
Turn the key to System, then Press Softkeys A, D, F. The MIDI terminal
window is displayed on the VDU screen. Turn the key to Run to finish.
