Backing Keyboard BK-5
The following parameters are available:
4.
Press the [EXIT] button to leave the “Eq Part
Edit” page.
Mfx
The BK-5 contains one multi-effects processor
(“Mfx”) that can be used to process the desired key-
board part(s). Select “Off” for parts that don’t need to
be processed by this Mfx.
Expression Pedal
Select “Off” if you don’t need pedal expression for the
selected part. This means that the keyboard part in
question no longer responds to an expression pedal
you may have connected to the SWITCH/EXPRESSION
socket.
Pedal Exp Down/Up
The expression pedal allows you to control the vol-
ume of all parts by foot.
“Up” and “Down” refer to the volume that is used
when the expression pedal is pressed (“Up”, highest
volume) or in the upright position (“Down”, lowest
volume).
You do not need to specify “0” for the “Down” posi-
tion. Selecting any other values will reduce the vol-
ume of the selected part up to the “Down” value.
Likewise, you do not need to specify “127” as maxi-
mum value for “Up”.
NOTE
The expression pedal sends MIDI Expression commands
(CC11).
It is perfectly possible to set the “Down” value to
“127” and the “Up” value to “0”, so that the selected
part only sounds when the expression pedal is in the
upright position. This can be used for some clever
effects: instead of alternating between the Upper1
and Upper2 parts by varying your velocity (which
requires a considerable amount of “striking preci-
sion”, see “Min Value” and “Max Value” on p. 57), you
could invert UP2’s response to the expression pedal,
so that UP1 doesn’t sound when UP2 does, and vice
versa.
Hold Pedal
This parameter allows you to specify whether and
how a hold/damper pedal you connect to the PEDAL
HOLD socket should respond to Hold messages
(CC64).
“Auto” means that the part in question only responds
to Hold messages if it is assigned to the right half
(Split) or the entire keyboard.
“On” means that the part in question always responds
to Hold messages, even if it is assigned to the left half
of the keyboard.
“Off”, finally, means that the part does not respond to
Hold messages.
Parameter Setting range Explanation
Switch Off, On This parameter allows
you to switch the
equalizer on and off.
High Freq 1500Hz, 2000Hz,
3000Hz, 4000Hz,
6000Hz, 8000Hz,
12000Hz Allows you to set the
cutoff frequency of
the high band (this is
a shelving filter).
High Gain –15~+15dB Use this parameter to
set the level of the
selected “High” fre-
quency. Positive val-
ues boost (increase
the volume of) that
frequency band, neg-
ative values cut
(attenuate) it.
Mid Freq 200~8000Hz Allows you to set the
cutoff frequency of
the middle band (this
is a peaking filter).
Mid Gain –15~+15dB Use this parameter to
set the level of the
selected “Mid” fre-
quency.
Mid Q 0.5, 1.0, 2.0, 4.0,
8.0 Use this parameter to
specify the width of
the “Mid Frequency”
band that you want to
boost or cut. Smaller
values mean that
neighboring frequen-
cies above/below that
value are also
affected.
Low Freq 90, 150, 180, 300,
360, 600Hz Allows you to set the
cutoff frequency of
the low band (this is a
shelving filter).
Low Gain –15~+15dB Use this parameter to
set the level of the
selected “Low” fre-
quency.
