115
controlling automatically selects the desired stereo
position. “0” corresponds to hard left, “64” to dead
center, and “127” to hard right. Note that the FR-7x
does not execute this message if it is returned to the
FR-7x via the external device’s “Soft Thru” function.
Select “Off” if the register should not transmit this
message.
■
Reverb
(Off, 0~127, Default setting: 40)
This parameter allows you to specify the Reverb Send
Level value (CC91) the register should send to an
external device when you press it. Selecting “0” will
set the receiving MIDI instrument to “dry” (no reverb),
while “127” represents the maximum Reverb Send
level. Select “Off” if the register should not transmit
this message.
Note: If there is no audible change, you may have to check
the reverb effect settings on the receiving MIDI instrument.
Note: Not all MIDI instruments have a reverb effect, and
even if they do, they may not support this control change
number.
■
Chorus
(Off, 0~127, Default setting: 0)
This parameter allows you to specify the Chorus Send
Level value (CC93) the register should send to an
external device whenever you press it. “0” will set the
receiving MIDI instrument to “dry” (no chorus), while
“127” represents the maximum Chorus Send level.
Select “Off” if the register should not transmit this
message.
Note: If there is no audible change, you may have to check
the chorus effect settings on the receiving MIDI instru-
ment.
Note: Not all MIDI instruments have a chorus effect, and
even if they do, they may not support this control change
number.
■
Velocity
(On, 1~127)
Your FR-7x is velocity sensitive. The volume and
brightness of the notes you play on the treble or bass
keyboard therefore depend on how hard (or fast) you
press the keys/buttons. The accordion sounds do not
respond to these playing dynamics, but the Orchestra
(Treble, Bass, Chord, Free Bass) sounds do and so do
most MIDI-compatible sound modules.
Even though the MIDI standard recognizes 128 dif-
ferent velocity values, only 127 can actually be used
for expression purposes. That explains why the set-
ting range is 1~127. Value “0” is usually used to sig-
nal the end of a note (i.e. when you release a key or
button).
This parameter allows you to specify whether the
velocity values corresponding to the strength with
which you press a key/button should be transmitted
(“On”) or whether your playing dynamics should not
be translated as such.
In the latter case, you need to select a value (1~127)
that will be applied to all notes that are transmitted
via MIDI. “64” is still relatively soft. Even lower values
are probably not what you want in most cases. Fixed
velocity values can be useful for playing organ
sounds on an external module.
Note that the setting you select here has no effect
when the “Note Tx” parameter is set to “Off”, because
note numbers are always transmitted along with a
velocity value (any value different from “0” also
means “start playing this note”).
■
Expression
(Off, Bellows, Pedal)
You probably noticed that the strength/speed with
which the bellows is pressed or pulled influences the
sound – which corresponds to an acoustic accor-
dion’s response.
This effect can be translated into a MIDI message
most external instruments understand. The MIDI
standard provides a message (“control change”) for
remotely controlling the volume of an external
instrument: CC11. It is chiefly used for expression
purposes (similar to the way in which a guitarist or
organ player uses a volume pedal).
If you want to use the bellows for expressive pur-
poses, set this parameter to “Bellows”.
If you don’t (because the external instrument is too
sensitive and therefore changes its volume too
often), select “Off”.
If you purchased an optional EV-series expression
pedal, which you connected to the FBC-7’s EXPRES-
SION PEDAL socket, you can also control the relative
volume by foot. In that case, set this parameter to
“Pedal”.
■
After Touch (only for the Treble and Orchestra
sections)
The treble keyboard of the piano-type model also
generates aftertouch messages (on the button-type
model, aftertouch can be generated with the Master
bar). Aftertouch is usually used for temporary
changes to a sound’s volume, timbre or pitch (this
needs to be set on the receiving instrument). Used
right, it can be a very powerful expressive tool.
Select “Off” if this message type should not be trans-
mitted. Select “On” if you want to transmit after-
touch messages.
