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
 
“

”
(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.

(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.
“

”
(Sync OFF)
MIDI Clock and Start/Stop/Continue mes-
sages will not be received.

 Choose this setting if you only want the 
SP-404’s samples to play in response to 
Note messages received from your exter-
nal MIDI sequencer.
