Description
Turns the Local Control on/off.
This is required when you want to trigger sounds in an external sound module and/or record
your performance on an external MIDI sequencer, and NOT use the TD-9's internal sounds.
If that is your need, then turn Local Control to "OFF." When recording/using TD-9 perfor-
mances on an external sequencer, turn Local Control to "OFF" and be sure the sequence's
MIDI OUT is connected to the TD-9's MIDI In.
The trigger signals from the pads go directly to the MIDI OUT/THRU connector.
The TD-9's default mode is with Local Control "ON."
If you make connections and record as shown, with a setting of Local Control "ON," dupli-
cate notes will be re-transmitted to the TD-9 and will not be played correctly.

Turns the Soft Thru function on/off.
This explains how you can use the Roland SPD-20 (a MIDI controller) together with the TD-
9's pads to play internal sounds and an external sound module.
When Soft Thru is set to "ON," the messages received at MIDI IN will also be transmitted
from the MIDI OUT/THRU connector.
