Connecting a MIDI Device
By connecting an external MIDI device and exchanging
performance data, you can control one device from another. For
instance, you can output sound from other instruments, switch
sounds or receive MIDI data from an external sequencer that cause
your FR-4x to play. See p. 82 for MIDI parameters.
What is MIDI?
MIDI, short for “Musical Instrument Digital Interface,”
was developed as a universal standard for the exchange of
performance data among electronic musical instruments and
computers.
The FR-4x is equipped with MIDI connectors to let it exchange
performance data with external devices. These connectors can be
used to connect the unit to an external device for even greater
versatility.
Connecting an external MIDI device to the FR-4x
The FR-4x has one MIDI connector that can be used to either
transmit (OUT) or receive (IN) MIDI data.
1. Turn the volume all the way down on the FR-4x and
the MIDI device you are about to connect.
2. Use a MIDI cable (sold separately) to connect the
MIDI connector to each other.
Connection to transmit MIDI data to an external device:
MIDI IN

cable
MIDI sound module
NOTE
If you connect or disconnect the AC adaptor while an
external device is connected to the MIDI OUT/IN connector,
unexpected data might be transmitted from MIDI OUT.
Don’t connect or disconnect the AC adaptor while an external
device that you’re using is connected to MIDI OUT.
