Chapter 12. Using the SP-505 with other MIDI devices
Never turn off the power while the display indicates
“Keep Power On!”
The SP-505 transmits pad performance data as sets
consisting of “program change message + note
message.” If this performance data is overdubbed on an
external sequencer, some sequencers may automatically
rearrange the overdubbed data, making it impossible for
the performance data to be reproduced correctly.
Synchronizing the
performance of the SP-505
and an external MIDI device
In order for the performance to be synchronized with an
external MIDI device, you must decide which device (the SP-
505 or the external MIDI device) will control start/stop, and
which device will determine the BPM (Sync mode).
Connections for synchronized
performance
Use a MIDI cable to connect the MIDI OUT connector of the
master device to the MIDI IN connector of the SP-505.
