The special channels
The Global channel
The Global is a special channel that allows you to sim-
ulate a keyboard integrated into the i40M. When the
i40M is connected to a keyboard, the keyboard should
transmit over the Global channel of the i40M.
According to the factory settings, the Global is pro-
grammed over channel 1 when the instrument is
turned on. Since most of the MIDI controllers transmit
over channel 1 when turned on, if no modifications
have been made, a MIDI controller and the i40M are
immediately connected over the Global channel.
The Global channel has the priority over the other
channels. For example, if the Global is programmed
over channel 1 and a track is programmed over chan-
nel 1 as well, the Global (with its settings and charac-
teristics) will control the track, not the standard
channel 1.
The MIDI messages received over the Global and not
over a standard channel are affected by the buttons of
the KEYBOARD MODE section (such as the split
point). Therefore, if the SPLIT button led is lit up, the
notes that arrive to the i40M over this channel will be
divided by the split point into the Upper (above the
split point) and Lower (below the split point) parts.
The notes that arrive to the Global channel are used for
the chord detection of the automatic accompaniment.
If the KEYBOARD MODE is SPLIT, only the notes
below the split point will be used. These notes will be
combined with the ones of the special Chord 1 and
Chord 2 channels.
The Global channel does not work in Song Play, Song
Edit, and Backing Sequence when the Extra Tracks are
selected. The reason is that in these operative mode the
information need to be channeled separately.
The Global channel works in Arrangement Play and
Backing Sequence when the arrangement tracks are
selected. It also works in Program mode, where all the
other channels are deactivated.
For information on the programming of the Global
channel, see "GLB (Global)" on page 139.
with the i40M. For more information, refer to special-
ized books and magazines.
The Chord 1 and Chord 2
channels
The notes that go through the Chord 1 and 2 channels
are used for the chord detection of the automatic
accompaniment. The notes will be combined with the
notes that go through the Global channel (under the
split point if the SPLIT led is lit up).
The Chord channels are not affected by the split point
and the KEYBOARD MODE section of the control
panel. All the notes – both above and below the split
point – will be sent to the chord detection.
The buttons of the CHORD SCANNING section have
a particular effect on the Chord channels:
• if you have selected LOWER, the chord detection
mode will be set by the "ChordRecog (Chord rec-
ognition mode)" parameter in the Global mode (see
page 147);
• if you have selected UPPER or FULL, the chord
detection mode will always be Fingered 2 (you
need to play at least three notes in order for the
chord to be detected).
These two channels are especially useful for accordion
players to assign a different Chord channel to the
chords and the bass played with the left hand. In this
way, chords and bass will participate to the creation of
chords for the chord detection of the automatic accom-
paniment.
For information on the programming of the Chord
channels, see "CHORD 1" and "CHORD 2" on
page 140.
The Keyboard Set channel
The Keyboard Set channel is used to receive the pro-
gram change messages for the Keyboard Sets. The
reception of a program change message over this chan-
nel will cause the selection of a Keyboard Set.
For information on the programming of the Keyboard
Set channel, see "KBSET (Keyboard Set)" on page 140.
