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-90 to an external MIDI device.

■Disconnecting the F-90’s keyboard and internal sound

generator (Local On/Off)

When the F-90 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).

If the F-90 is connected to a Roland MT series (except MT- 80s/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-90 and then the MT series, the F-90 will automatically be set to Local Off.

■Receiving on all MIDI channels

(Omni On/Off)

When set to Omni On, the F-90 will sound as a result of received MIDI messages, no matter which channel the messages arrive on.

When set to Omni Off, the F-90 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 [Demo] button, and press the “A7” note to turn the setting On, or the “G7” note to turn the setting Off.
