Chapter 12. Using the SP-505 with other MIDI devices
* Do not use a MIDI cable to directly connect the SP-505’s
MIDI IN connector to its own MIDI OUT connector (creating
a loop). The SP-505 may fail to operate correctly if this is done.
About MIDI
MIDI stands for Musical Instrument Digital Interface. It is a
universal standard, designed to provide for the exchange of
performance data among electronic musical instruments,
computers, and other devices. The SP-505 supports the use of
MIDI, and provides two MIDI connectors: MIDI IN and
MIDI OUT. These connectors can be connected to other MIDI
devices, thus greatly expanding your performance
possibilities.
About the MIDI connectors
The SP-505 has the following MIDI connectors.
MIDI IN:
Receives MIDI messages from other MIDI devices.
MIDI OUT:
Transmits MIDI messages from the SP-505.
About the MIDI implementation chart
The MIDI implementation chart (p. 87) provides an easy way
to view the types of MIDI message that the SP-505 can
transmit and receive. Compare the SP-505’s MIDI
implementation chart with the implementation chart of some
other connected MIDI device, and use the MIDI messages
that are recognized by both devices.
For details of the SP-505’s MIDI functionality, refer to “MIDI
implementation.
Changing the MIDI settings
MIDI parameters

Sync Mode: INT, MIDI, REMOTE, AUTO
Specify the mode used when synchronizing the SP-505’s
performance with an external MIDI device.
For details refer to “Synchronizing the performance of
