NOTE
Local Control Off is lifted and Local Control On restored the next time the power is turned on.
Regardless of the Local Control setting, messages received at MIDI IN will play the internal sound
MEMO
generator, and the pads and pedals will transmit messages from MIDI OUT.

If you have connected the SPD-20 to a MIDI sequencer (or a personal computer running MIDI
MEMO
sequencing software) that has a "soft(ware) thru" function, set the SPD-20 to Local Off.
Soft Thru
"Soft thru" is a function (provided in most MIDI sequencers) by which the messages received at
MIDI IN of the sequencer are re-transmitted from MIDI OUT. (For details, refer to the manual of
your sequencer or sequencer software.)
When the sequencer's soft thru is turned on, messages it receives at its MIDI IN will be re-trans-
mitted from its MIDI OUT. If the connected SPD-20 is set to Local On, it would sound each note
twice: once in response to the message from the pad section, and once again in response to the
MIDI message sent via the software thru function of the sequencer.
It is also useful to set Local Off when using the SPD-20 as a pad controller to play only external sound
MEMO
modules.
Turn off the power switch.
While pressing [PATCH CHAIN], turn the power switch back on.
The following message will scroll across the display, and Local Control will be turned off.
When Local Control is set to "Off," the internal sound generator does not sound, even
when the Pad is struck, and in PLAY mode, the MIDI Indicator lights.
