Connecting to MIDI Devices
Cautions when Connecting
an External MIDI Device
Here we will explain the “Local On/Off” and “Omni On/
Off” settings that you need to be aware of when connecting
the pt-2700 to an external MIDI device.
■ Disconnecting the pt-2700’s
keyboard and internal sound
generator—Local On/Off
When the pt-2700 is connected to a MIDI sequencer or the
like, set it to Local Off.
As shown in the diagram, the data that is produced when
you play the keyboard will reach the sound generator by two
routes, (1)and (2), causing each note to be played in
duplicate. To prevent this, select the Local Off setting to cut
route (1).

NOTE
Be aware that if you set your instrument to Local Off when no
external MIDI device is connected, there will be no sound.
■ Switching Local On/Off
Local On is set when the power is switched on.
While holding down the [GRAND PIANO]
button, [UPRIGHT PIANO] button, and
[STRINGS] button, the “B4” note to turn the
setting On, or press the “C5” note to turn
the setting Off.
fig.8-07.e
If the pt-2700 is connected to a Roland MT series (except MT-
90s), it is not necessary to make the Local Off setting. When
the power is turned on, the MT series will transmit a Local
Off message. If you turn the power on in the order of first the
pt-2700 and then the MT series, the pt-2700 will
automatically be set to Local Off.
