About MIDI
MIDI stands for Musical Instrument Digital Interface, and is
a global standard that allows electronic musical instru-
ments and computers to exchange performance data.
"MIDI Implementation Chart" (p. 48) is a chart that provides
an easy way of checking which MIDI messages the
SP-404SX is able to receive. By comparing the MIDI
implementation charts of the SP-404SX and some other
MIDI device, you can see which messages are compatible
between the two devices.

to play the SP-404SX's patterns later at the desired

of your external MIDI sequencer, so that the two
performances do not begin at the same time.
MIDI clock and start/stop/continue messages will
not be received. Select this mode of operation

Synchronizing the pattern tempo and playback
start/stop with an external sequencer
With the factory settings, the SP-404SX (whose MIDI
synchronization mode will be set to "A U t") can be con-
nected to your external MIDI sequencer, and the external
MIDI sequencer can control the start/stop and tempo of
the pattern playback.
1. Use a MIDI cable to connect your external MIDI
sequencer's MIDI OUT to the SP-404SX's MIDI IN
connector .
2. Press the [PATTERN SELECT] button so the button
is lit .
3. While holding down the [HOLD] pad, press the
pad of the pattern you want to play .
If you simply press the pad without pressing the [HOLD]
pad, the pattern will begin playing immediately.
4. When you stop your external MIDI sequencer, the
pattern will stop playing .
If the pattern playback does not start when you start
your external MIDI sequencer, or if the tempo does not
synchronize to your external MIDI sequencer, it is possible
that your external MIDI sequencer is not transmitting
MIDI clock or start/continue/stop messages. Refer to the
owner's manual of your external MIDI sequencer and check
its settings.
