Configuring the AX-7
12
Select LL if all note messages of the section in
question are to be transmitted with more or less the
same velocity value. Extreme differences in dynam-
ics (hitting very hard and very soft) will, however,
allow you to trigger velocity switches if the receiv-
ing MIDI instrument supports that feature. This set-
ting is thus not the same as “off” on other instru-
ments – but it is very similar.

oct
(Octave)
Upper, Lower
This parameter is especially useful in Split mode (see
p. 9), when you wish to use your left hand for a
chord backing whose register is close to the part you
play with your right hand. Of course, you can also
transpose (or “shift”) the Upper part in octave steps,
which may be useful in Layer mode.
The setting range is –2, –1, 0, 1, 2 octaves (down or
up). Note that the AX-7’s keyboard can also be
transposed in semitone steps. See page 17.

dbm
(D Beam)
Upper, Lower
The D Beam Controller allows you to control various
aspects of your performance, or to add something
to the music, by moving your hand, head, etc., in the
air. You only need to make sure that you do so over
the two “eyes” and within a 40cm (±16”) range. Your
movements are translated into musical expression.
(1) Press the D BEAM [ON/OFF] button (indicator
must light).
(2) Move your hand towards and away from the
D Beam’s “eyes”.
The active section now transmits the assigned mes-
sages. Here are the functions that can be assigned
to the D Beam controller (after selecting the dbm
parameter):
Ar1, Ar2, Ar3: The D Beam can be used for playing
arpeggios on the external MIDI instrument. The
number (1, 2, 3) refers to the number of octaves that
are covered by the arpeggio function. See also “Get-
ting the D Beam to play the notes you want” (p. 13).
The tempo depends on the speed of your move-
ments towards the D Beam.
Crd: The D Beam can be used for playing chords (i.e.
transmitting several note messages simultaneously).
See also “Getting the D Beam to play the notes you
want”.
nte: The D Beam transmits one note-on message.
See [7] on page 13 for how to specify the note num-
ber. This can be useful for triggering “noises” of an
XV synthesizer or module, loops, hits, or other sam-
ples.
11u/11d: With these options, you assign the Con-
trol Change CC11 (Expression) to the D Beam con-
troller (for the selected section). The u means that
the D Beam can be used for transmitting values
between “0” (volume effectively set to zero) and
“127” (volume corresponding to the value set for
CC07 on the receiving MIDI instrument), while d
refers to the value range “127”~“0”.
What’s the difference? If you select 11u, the receiv-
ing MIDI instrument can be faded in – i.e. it is only
audible when the D Beam senses your hand. 11d
allows you to produce fade-outs. Assigning one to
the Upper and the other to the Lower section after
selecting Layer mode (see p. 9) thus allows you to
produce cross-fades in Realtime.
16u/16d~19u/19d, 71u/71d~78u/78d: With
these options, you assign the corresponding Control
Change number (CC16~19 or CC71~78) to the D
Beam controller (again for the selected section). The
u means that the D Beam allows you to transmit
values between “64” and “127”, while d refers to the
value range “64”~“0”. This is mainly intended for rel-
ative changes to value of the external MIDI instru-
ment’s parameter that responds to the CC number
in question. CC71~78 are meaningful for GM2 com-
patible tone generators, though other MIDI instru-
ments may receive them and control another
parameter – which can be as interesting.
As long as the D Beam does not sense any move-
ment, the value will be “64”, which is the relative
neutral position (no change to the parameter value).
CC16~19 are “General Purpose” Control Changes,
which is a learned way of saying that they have no
standardized function yet and can thus be used at
will by each manufacturer. If your MIDI instrument
(usually a programmable synthesizer) allows you to
use these messages for controlling certain parame-
ters, the D Beam can perform the same function as
an “assignable controller”. (See your MIDI instru-
ment’s manual for details.)
