MIDI THRU/OUT jack
This standard 5-pin DIN connector can be connected to the MIDI IN jack of another
device via a standard MIDI cable. There are limitations to the number of devices that can
be chained (or series connected) in this fashion.
Note:
Inherently in MIDI there is a limit to the number of devices which can be
chained together (connected in series). With more than 3 devices, a slight
distortion of the MIDI signal can occur (due to signal degradation) which can
cause an error in MIDI signal transmission. Should this problem arise, a MIDI
Thru box can be used which connects directly to the MIDI device which
transmits MIDI information and has multiple connectors for the multiple
devices receiving MIDI. MIDI cables should not exceed 50 feet (15 meters) in
length.
