About MIDI...
MIDI (pronounced middy) stands for Musical Instrument Digital Interface. MIDI is a
world-wide standard that allows musical instruments and computers to exchange
musical data. Most electronic musical instruments sold today are MIDI compatible.
MIDI compatible devices have MIDI connectors which are used to physically link in-
struments (using special cables). MIDI does not transmit the sound of an instrument, but
rather messages in digital form that tell the receiving instrument to do something. These
are known as MIDI messages.
e Another MIDI keyboard or MIDI sequencer can be used to play the sounds
in the HP-3800/2800.
¢ The HP-3800/2800 can be played and used to trigger other instruments or
sound modules equipped with MIDI.
e What you play on the HP-3800/2800 can be recorded into a sequencer.
Three MIDI connectors are provided on the instrument's rear panel: IN, OUT, and
THRU.
MIDI
MIDI IN
MIDI data is received through this connector. To have the HP-
3800/2800 played by a sequencer or other MIDI device, con-
nect a MIDI cable so it runs from here to the MIDI OUT or
MIDI THRU connector on the external device.
MIDI OUT
MIDI data is transmitted from this connector. To play the sounds of an
external MIDI instrument or sound module, or record what you play into
a sequencer, connect a MIDI cable between here and the MIDI IN con-
nector on the external device.
MIDI THRU
An exact copy of MIDI signals arriving at this instrument's MIDI IN connector are
retransmitted from this connector.
Connections between MIDI connectors should be made using a MIDI cable as shown
in the figure below (option: MSC-15/25/50).
