MIDI

stands for Musical Instrument Digital Interface. It is a universal
standard that allows electronic musical instruments and computers
to exchange performance data. The SP-404 supports the MIDI
standard, and provides a MIDI IN connector. You can connect this
connector to another MIDI device to do a variety of things.
The SP-404’s

MIDI IN

connector receives MIDI messages from
another connected MIDI device.

The “MIDI Implementation Chart” (p. 51) provides an easy way
to check which MIDI messages the SP-404 is able to receive. You
can compare this chart to the MIDI implementation chart of
your other MIDI device to see which messages can actually be
sent by your other device and received by the SP-404.
To play the SP-404’s pads using an external MIDI device, transmit
the following note numbers.

You can change the MIDI channel by changing the

Pad Base
Ch
.
Here’s how to specify the channel (Pad Base Channel) on which you
can play the SP-404’s pads from an external MIDI device.
1.
Refer to the following table, and turn on the power while
holding down the pad that corresponds to the channel you
want to use.

This setting is remembered even after you turn off the power.

1.

While holding down [TIME/BPM], turn on the power.

The MIDI synchronization mode will appear in the display. The
MIDI synchronization mode determines how the SP-404
operates in synchronization with another device.

2.

Turn the CTRL 1 (TIME) knob to select the MIDI
synchronization mode.

With the factory settings, “Aut” is selected.

Explanation

“

Aut

”
(Auto Sync)
When MIDI Clock messages are received,
the SP-404 will automatically detect them
and synchronize to their tempo. MIDI
Start/Stop/Continue messages can be re-
ceived to start/stop pattern playback.
*
MIDI Start/Stop/Continue messages will
not be received during pattern recording.
“
tMp
”
(Tempo Sync)
When MIDI Clock messages are received,
the SP-404 will automatically detect them
and synchronize to their tempo. MIDI
Start/Stop/Continue messages will not be
received.
*
Choose this setting if you want to play the
SP-404’s patterns at the timing you choose
but in synchronization with a perfor-
mance sent from an external MIDI se-
quencer.
“
oFF
”
(Sync OFF)
MIDI Clock and Start/Stop/Continue mes-
sages will not be received.
