Chapter 7. Using the SP-303 With Other MIDI Devices
Note On Operating With MIDI
If you are using a MIDI device to play samples from the SP-
303, you must change the way the external MIDI device’s
note messages are sent when playing samples using Trigger
Playback and Gate Playback.
When Using Gate Playback
fig.r07-03
When using Gate Playback, where the sound plays only
as long as the pad is held down, send a Note On message
at the point you want the sound to start playing, and
send Note Off at the point you want the sound to stop.
When Using Trigger Playback
When set to One Shot Playback ([LOOP] not lit):
fig.r07-10
Send a note message at the point you want the sound to
begin. When the note message is received, the sample is
played back, starting from the beginning of the sample.
In this case, the interval from the Note On message to the
Note Off message can be as short as you want.
The sample stops playing when the end of the sample is
reached.
When set to Loop Playback ([LOOP] lit):
fig.r07-02
Send a note message at the point you want the sound to
begin and when you want it to stop. In this case, the
interval from the Note On message to the Note Off
message can be as short as you want.
* You can change the playback volume on the SP-303 by
receiving Note On Velocity.
* The last pad to play becomes the current pad.
* When continuously playing a sample of a looped phrase along
with a MIDI sequencer performance, the rhythm between them
may diverge as time passes. In such instances, rather than
using Loop Playback, use One Shot Playback and send a Note
On message from the MIDI sequencer to the SP-303 at the
beginning of each measure (or sampling measure).
* You cannot change the BPM settings for the SP-303’s samples
with MIDI clock.
Using the SP-303 With a
MIDI Sequencer (Tempo Sync)
Here is an explanation of how to connect a MIDI sequencer
to the SP-303 and synchronize the SP-303’s patterns with the
MIDI sequencer.
Synchronizing the Pattern’s Tempo
and Start/Stop to the MIDI Sequencer
At the factory settings, you can simply connect a MIDI
sequencer to the SP-303, and you use the sequencer to control
the start and stop of patterns, as well as the tempo.
fig.r07-04
1. Connect the MIDI sequencer’s MIDI OUT connector to
the SP-303’s MIDI IN connector with a MIDI cable.
2. Press [PATTERN SELECT], and confirm that the
button has lit.
3. Press one of BANK [A]–[D] to select the bank holding
the pattern you want to play.
* If there is no memory card inserted in the slot, you will be
unable to select Pattern Bank C or D.
4. Hold down [REMAIN] and press the pad for the
pattern you want to play (specify the pattern).
The pad for the specified pattern lights up.
* Take care to note that the pattern will suddenly start playing if
you only press the pad without holding down [REMAIN].
