Page 2: Echo Back / MIDI IN Octave
The Echo Back function allows you to connect a digital
piano and create a “muted” keyboard area for the
chord composition for the automatic accompaniment.
In order to use this function, you need to connect the
MIDI OUT connector of the i40M to the MIDI IN con-
nector of the piano, and the MIDI IN 1 or 2 connector
of the i40M to the MIDI OUT connector of the piano.
When you activate the function, the i40M will send a
Local Off message through the MIDI OUT, while dis-
connecting the internal sounds of the piano from the
piano keyboard.
If the function is active when you turn the i40M off,
the Local Off message will be sent to the piano when
turning the instrument on. Therefore you need to turn
on the digital piano first, and then the i40M.
When the Echo Back function is active, when playing
on the piano keyboard, the MIDI messages will be sent
to the MIDI IN connector of the i40M, which will send
them back to the piano.
The Echo Back function is used by the MIDI “Digital
piano 1” and “Digital piano 2” setups (see “Connect-
ing the i40M to a digital piano” on page 48).
Echo Back
[DISABLE, IN 1, IN 2]
Select the MIDI IN port used for connecting the piano
to the i40M. “Disable” means that the function is des-
activated.
Note: When the Echo Back function is active, the i40M
will send a Local Off message over the MIDI OUT connec-
tor when you turn the i40M on. Turn on the piano before
turning the i40M on.
Oct (MIDI IN Octave)
[-2…0…+2]
This function will transpose the incoming MIDI notes
by one or more octaves. It is particularly useful to
accordion players to modify the octave in which the
right hand (Upper 1/Upper 2) and left hand (Lower)
notes are received.
L Lower track transposition.
U1/U2 Upper 1 and Upper 2 track transpo-
sition.
Echo Back: DISABLED
