Mastering Tools
The BK-5 contains an effects processor that applies to
all real-time, rhythm and SMF song parts.
This processor is called “Mastering Tools”, because it
allows you to perfect the signal mix to adapt it to the
sound system you are using.
The parameters discussed here can be selected using
[MENU] button ‰ “Mastering Tools”.
Compressor
This multi-band compressor/limiter allows you to pro-
cess three frequency ranges separately. A compressor
reduces high levels (peaks) and boosts low levels,
smoothing out fluctuations in volume.
To edit the Compressor parameters, use [MENU] button
‰ “Mastering Tools” ‰ “Compressor”.
1.
Select a keyboard part, an SMF song or a
rhythm and start playback.
2.
Set the “Switch” parameter to “On” to acti-
vate the compressor.
The compressor is now active. (Select “Off” to switch
the compressor back off.)
3.
Use the [CURSOR÷VALUE] dial to select the
“Preset” parameter, then press the [ENTER/
SELECT] button.
4.
Rotate the [CURSOR÷VALUE] dial to select
one of the available presets.
The available presets are:
5.
If none of the preset memories contains the
settings you need, press the [ENTER/SELECT]
button to select and set the following
parameters:
1. Hard Comp
2. Soft Comp
3. Low Boost
4. Mid Boost
5. High Boost
6. Standard
7. User
Parameter Setting Explanation
Level 0~127 Use this parameter to set
the compressor’s input level.
The higher the value, the
stronger the three frequency
bands are compressed.
The value you set here is
added to the “Level” settings
of the three bands. Do not
set this parameter to “0” if
the compressor is switched
on, because doing so means
that the keyboard parts, the
SMF song or Rhythm parts
are no longer audible.
Gain –12~0~
12dB
Use this parameter to cor-
rect the level at the com-
pressor’s outputs. If the
settings of the remaining
parameters lead to a signifi-
cantly lower level, select a
positive value. If your set-
tings lead to a significantly
higher level, select a nega-
tive value. “0” means that
the level is neither boosted
nor attenuated.
High/Mid/Low: Because “Attack”, “Release”, “Threshold”,
“Ratio” and “Level” are the same for each band, we will
only discuss them once. As you see, each of the three fre-
quency ranges has its own set of parameters that allow
you to specify their behavior.
Attack 0~100ms Use this parameter to spec-
ify how fast the compressor
of the band in question
should start processing the
signal once the level of that
band exceeds the “Thresh-
old” level. Choose a smaller
value if you prefer a com-
pression similar to that of
FM radio stations. Higher
values may yield a “snap-
pier” or “funkier” sound.
Release 50~
5000ms
This parameter allows you to
specify how fast the com-
pressor of the corresponding
band should stop working
when the signal level drops
below the “Threshold” value.
