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 ep-97/77 to an external MIDI device.
Disconnecting the ep-97/77's keyboard and inter-
nal sound generator—Local On/Off
When the ep-97/77 is connected to a MIDI sequencer
or the like, set it to Local Off. As shown in the dia-
gram, 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.
Note: Local On is set when the power is switched on.
While holding down the (Piano 1) button, (Piano 2]
button, and [Harpsichord] button, press the “B4”
note to turn the setting On, or press the “C5” note to
turn the setting Off.
Note: Refer to “Functions assigned to the keyboard” on
page 22 for the exact keys to press.

If the ep-97/77 is connected to a Roland MT series
(except MT-80S), it is not necessary to make the Local
Off setting. When the power is turned on, the MT will
transmit a Local Off message. If you first switch on
the ep-97/77 and then the MT, the ep-97/77 will auto-
matically be set to Local Off.
Receiving on all MIDI channels—Omni
MIDI features sixteen MIDI channels, numbered
1~16. The connected devices must be set to use the
same MIDI channel as the ep-97/77, otherwise no
sound will be produced.
When set to Omni On, the ep-97/77 receives on all
MIDI channels, so that you do not need to set a spe-
cific one. This may be practical for playing back
sequences containing piano music on different chan-
nels for the left and right hands. It should not be used,
however for playing back commercial Standard MIDI
Files as that will cause the ep-97/77 to produce so
many notes that you hardly recognize the piece in
question.
Omni Off is automatically set when the power is
switched on.
Hold down the [Piano 1] button, the [Piano 2] but-
ton, and the [Harpsichord] button, and press the
“F4” note to turn the setting On, or the “G4” note to
turn the setting Off.
Note: Refer to “Functions assigned to the keyboard” on
page 22 for the exact keys to press.
