Using MIDI clocks to synchronize with an external MIDI device
When the SL-2 receives a timing clock (F8H), a start message (FAH), a continue message (FBH) or a stop message (FCH), this device
synchronizes its tempo to the external device.
●You can’t use the following operations to set the tempo of the SL-2 while it is synchronized to MIDI clocks.
-Tempo settings (tap tempo) using the pedal switch of the SL-2 or a footswitch connected to the SL-2
-Tempo settings by receiving control change messages (CC#81)
●Tempo settings made via MIDI clocks are not stored in this device.
●MIDI clocks are part of the MIDI system common information (system real-time messages). As such, they don’t have
MIDI channel settings.
