Operating the SL-20

Synchronizing Performances with External

MIDI Devices

MIDI (Musical Instrument Digital Interface) is a universal standard that allows for the
exchange of performance data and other information among electronic musical instruments
and computers. Once MIDI cables are used to connect together devices equipped with MIDI
connectors, each device can send data to, or receive data from any of the others. You can
synchronize the SL-20 with performances played on an external MIDI device.

Data Synchronized with the SL-20

The following MIDI messages are handled during synchronization with the SL-20.
• Timing Clock
• Start
• Continue
Timing Clock corresponding to the tempo is transmitted from the master device
(external MIDI device). The slave device (SL-20) synchronizes its performance to the
transmitted Timing Clock. Start and Continue MIDI messages are also transmitted
when these operations are carried out with the master device (external MIDI device).
Upon receiving the Start message from the external MIDI device, the SL-20 starts its
slice pattern from the top. Upon receiving the Continue message, the SL-20 continues
to playback from the current position in sync with the external MIDI device.

* For more information on the MIDI messages handled by the devices you are connecting, refer to the
owner’s manual for each device.

1.

Connect the external device to the MIDI IN connector.

2.

Transmit the MIDI messages from the external MIDI device.

The SL-20’s performance is synchronized according to the MIDI messages from the
external MIDI device.

* You cannot set the tempo with the SL-20 while MIDI clock is being received.
* In some cases, when the SL-20 receives the MIDI Clock and synchronization of the performance begins,
the SL-20 may pause for several seconds. Afterwards, the performance is synchronized to the
transmitted Timing Clock.

* If the MIDI cable is disconnected during a synchronized performance, the SL-20’s performance stops playing.
Approximately one second after that, the slice pattern begins playing at the SL-20’s internal tempo setting.
