to “dry” (no Reverb), while “127” represents the maxi-
mum 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 
(this is especially true of older instruments).
Chorus
(Off, 0~127, Default: 0) This parameter allows you to 
specify the Chorus Send Level value (CC93) to be 
transmitted by the register whenever you select 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 instrument.
Note: Not all MIDI instruments have a chorus effect and even 
if they do, they may not support this control change number 
(this is especially true of older instruments).
Velocity
(On, 1~127) Your FR-7/FR-5 is velocity sensitive. That 
is a very learned term for the fact that the volume 
and brightness of the notes you play on the Treble or 
button keyboard 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 and 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, so even lower values are probably not what you 
want in most cases. Fixed velocity values can be use-
ful for playing organ sounds on an external module.
Note that the setting you select here has no effect 
when the “Note” 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”). Sending only a 
velocity value without specifying the note to which it 
applies doesn’t make sense.
Expression
(Off, Bellows, Pedal) You probably know that the 
strength/speed with which the bellows is pressed or 
pulled influences the sound – which corresponds to 
an acoustic accordion’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-5 expression pedal, 
which you connected to the FBC-7’s EXPRESSION 
PEDAL socket, you can also control the relative vol-
ume by foot. In that case, set this parameter to 
“Pedal”.
AfterT (only for the Treble and Orchestra sec-
tions)
The Treble keyboard also generates aftertouch mes-
sages. 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. 
The downside is, however, that aftertouch messages 
usually represent a massive amount of data, which 
makes it a lot harder to find the MIDI messages you 
want to edit on an external sequencer, not to men-
tion the fact that your song files become a lot 
heavier than they need to be.
Besides, many sounds/parts on external MIDI instru-
ments are set to ignore these messages by default, so 
that you would end up sending a lot of information 
for nothing. That is why we recommend setting this 
parameter to “Off” and only select “On” if you really 
mean to take advantage of the Treble keyboard’s 
aftertouch capability.
