11. If you don’t need to edit some parameters that
characterize the sound of a single drum instrument,
proceed from the step 15.
Editing a Single Drum Instrument
12. Press the [QUICK MENU] button, that is ashing.
The BK-9 shows the following page:
Left Display
13. Use the dial to select the “Rhythm Tone Edit function.
The following page is shown:
Right Display
The rst row shows the name of selected Drum instrument.
14. Press a note in the keyboard or use the dial to select the
Drum instrument to edit.
The name of the Drum instrument corresponding to the played
note is shown in the rst row.
15. Use the dial to edit the following parameters:
Parameter Value Explanation
Pitch Fine -50~0~+50
This parameter allows you to set the ne tune of the
selected Drum Instrument.
Pitch Coarse 0~127
This parameter allows you to set the coarse tune of
the selected Drum Instrument.
Chorus Send 0~127
Use this parameter to set the chorus send level of
the selected Drum Instrument.
Reverb Send 0~127
Use this parameter to set the chorus send level of
the selected Drum Instrument.

Selects the type of lter. A lter modies the
brightness or thickness of the sound by cutting a
specic frequency range:
OFF”: No lter used
LPF”: Low Pass Filter. This reduces the volume
of all frequencies above the cuto frequency
(Cuto Freq) in order to round o, or un-brighten
the sound. This is the most common lter used in
synthesizers.
BPF”: Band Pass Filter. This leaves only the
frequencies in the region of the cuto frequency
(Cuto Freq), and cuts the rest. This can be useful
when creating distinctive sounds.
HPF”: High Pass Filter. This cuts the frequencies
in the region below the cuto frequency (Cuto
Freq). This is suitable for creating percussive
sounds emphasizing their higher tones.
PKG”: Peaking Filter. This emphasizes the
frequencies in the region of the cuto frequency
(Cuto Freq). You can use this to create wah-wah
eects by employing an LFO to change the cuto
frequency cyclically.
LPF2”: Low Pass Filter 2. Although frequency
components above the Cuto frequency (Cuto
Freq) are cut, the sensitivity of this lter is half
that of the LPF. This makes it a comparatively
warmer low pass lter. This lter is good for use
with simulated instrument sounds such as the
acoustic piano.
LPF3”: Low Pass Filter 3. Although frequency
components above the Cuto frequency (Cuto
Freq) are cut, the sensitivity of this lter changes
according to the Cuto frequency. While this
lter is also good for use with simulated acoustic
instrument sounds, the nuance it exhibits diers
from that of the LPF2, even with the same TVF
Envelope settings
TVF Cuto 0~127
Selects the point at which the lter begins to have
an eect on the waveforms frequency components.
TVF Resonance 0~127
Emphasizes the portion of the sound in the region
of the cuto frequency, adding character to the
sound. Excessively high settings can produce
oscillation, causing the sound to distort.
TVF Env Depth -63~0~+63
Species the depth of the TVF envelope. Higher
settings will cause the TVF envelope to produce
greater change. Negative (-) settings will invert the
shape of the envelope.
TVF Env A
0~127
Specify the TVF envelope times (Time A–Time R).
Higher settings will lengthen the time until the next
cuto frequency level is reached

TVA Level 0~127
Sets the volume of the tone. This setting is useful
primarily for adjusting the volume balance between
tones.
TVA A
0~127
Specify the TVA envelope levels (Level A–Level R).
These settings specify how the volume will change
at each point, relative to the standard volume (the
Tone Level value specied in the TVA screen).
