MIDI
The Musical Instrument Digital Interface (MIDI) was originally conceived to standardise the
interconnection between keyboards and other instruments. It is now found on all types of equipment
including sound and lighting consoles, effects devices and computers. Sophisticated recording is now
possible by interfacing sound consoles with other MIDI equipment.
The GS3000 includes a full opto-isolated Musical Instrument Digital Interface (MIDI) system. Standard 5-
pin IN, OUT, THRU DIN sockets allow connection to external MIDI equipment including computers,
sequencers, data archiving systems, musical instruments and so on. The console mute system can
control or be controlled using MIDI. Applications include sophisticated 'hands-off' mute control of effects,
instrument patch control, and archiving of the mute settings for recall.
Pressing console mutes transmits MIDI Note On messages. Recalling patches transmits MIDI Program
Change messages. Similarly receiving the MIDI Note On and Program change messages overwrites the
console mutes and patches. The console mute memory can be dumped out or in using MIDI System
Exclusive messages. The console can be set to operate on any MIDI channel and if required MIDI can
also be disabled.
The MIDI Cables
Use high quality screened twisted pair cable with the screen connected to pin 2 at both ends. The cable
should be no longer than 15m (50’) and terminated with 180º 5pin male cable mount DIN plugs. MIDI
cables are available from you local audio dealer or music shop. To control external equipment, connect
the MIDI OUT of the console to the MIDI IN on the external equipment. To control the console, plug the
MIDI OUT or THRU of the external equipment to the console MIDI IN. To pass MIDI through the console
to the external equipment plug the console MIDI THRU to MIDI IN on the external equipment.
