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 F-100 to an external MIDI device.
■ Disconnecting the F-100’s
keyboard and internal sound
generator (Local On/Off)
When the F-100 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.
1. While holding down the [Variation] button and
[Song] button, the “C8” note to turn the setting
On, or press the “B7” note to turn the setting Off.
fig.8-07.e
If the F-100 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
F-100 and then the MT series, the F-100 will automatically be
set to Local Off.
■ Receiving on all MIDI channels
(Omni On/Off)
When set to Omni On, the F-100 will sound as a result of
received MIDI messages, no matter which channel the
messages arrive on.
When set to Omni Off, the F-100 will recognize only the
messages that arrive on the MIDI channel that has been
selected, as explained under “Set the MIDI Channel.”
■ Switching Omni On/Off
Omni On is automatically set when the power is switched on.
1. Hold down the [Variation] button and [Song]
button, and press the “A7” note to turn the setting
On, or the “G7” note to turn the setting Off.
