CC78 Vibrato Delay
'Freeze' function
If you set [3] bar (see p. 11) to 0ff and assign a
11u~78d option to the D Beam, the EXPRES-
SION BAR can be used for "locking" the last
value generated by your movements over the D
Beam Controller.
That would allow you, for example, to raise (or
lower) the MIDI instrument's Cutoff setting via
74u (or 74d) and to keep using the new value
almost indefinitely. To do so:
• Move your hand inside the D Beam's range.
• While doing so, press the EXPRESSION BAR,
then release it and move your hand outside the
D Beam's range.
• To generate a new value, move your hand again
inside the D Beam's range.
Getting the D Beam to play the notes you
want
The ar and Crd options mean that the D Beam
controller transmits several note-on messages.
Before showing you how to specify those notes,
there is something else you need to know: a
section (Upper or Lower) to which one of the
above D Beam functions is assigned, cannot be
triggered via the keyboard while the D BEAM
[ON/OFF] indicator lights.
The D Beam thus acts as "trigger" for the note
numbers to be assigned. If any combination of
the Ar~Crd options is assigned to both sec-
tions, you won't hear the notes you play on the
AX-7's keyboard while the D BEAM [ON/OFF]
button is on.
To specify the notes the D Beam should use
for its chords or arpeggios, you need to proceed
as follows:
• Select Split or Layer mode.
• Press the D BEAM [ON/OFF] button (indicator
must light).
• Play the notes on the keyboard (using keys that
are assigned to the section that is controlled by
the D Beam).
r AX-7 Owner's Manual
• While holding those notes, press the Sustain
button (on the bottom of the "neck" section).
Release the keys (and possibly also the Sustain
button).
• Move your hand within the D Beam's sensing
range to cause the D Beam to first transform
those notes (in the case of Ar1~Ar3) and then
transmit the result.
[7] dbn (D Beam Note)
This parameter allows you to specify which note
number should be transmitted whenever the D
Beam senses your hand. This is only meaningful if
you assign the nte D Beam function to a section
(see p. 12). The setting range is 0~127 (displayed as
C-~G9).
This function is useful for producing special effects,
like triggering sampled grooves, certain noises that
add to the realism of your performances, or sounds
to impress your audience (orchestra hits, gongs,
explosions, etc.)
[8] bch (Battery Check)
This parameter allows you to check the voltage of
the batteries (0~100). The value "0" means that the
batteries should be dead by now, while "100" repre-
sents the highest value. A flashing dot in the left
part of the display means that the remaining bat-
tery power is less than 30%.
Note: This value is only meaningful if no adaptor is con-
nected to the DC IN socket (if an adaptor is connected, the
value will always be 100).
Note: For important occasions, it may be wiser to work with
an optional ACA adaptor. That way, you can rest assured that
you will not run into problems during the session or gig.
