The Midi “Program Change” command, which consist of only two consecutively transmitted bytes, is
used to control DMX channels 1-255 all at the same time, in unison. The most common use of this
command is to turn all DMX channels OFF (brightness of 0). The format is as follows:
General Information
MIDI and DMX
In the Musician word, MIDI is the standard way of controlling things. From instruments to effect boxes,
even switching between devices or amps, MIDI is the protocol that links everything together. Stage
Lighting, on the other hand, is controlled by the DMX512 communication protocol. Unfortunately the
two protocols do not mix. The Skutch EX-100 bridges that GAP by converting MIDI messages into
DMX512 messages. This gives you the ability to control your stage lighting directly with your MIDI
output. It should be noted that all stage lighting is not DMX compatible. DMX512 is definitely the NEW
standard for controlling stage lights. You MUST make sure that the lights used with the EX-100 are
DMX512 type. Even some FOG machines and HAZERS are DMX controllable.
