User Drum Kit Parameters
You can edit the following parameters.
Common parameters
These parameters applied to the entire drum kit.
The Common parameters appear when you press the [F1] (Common)
button in the User Drum Kit Edit screen.
Wave parameters
These parameters can be edited for each individual element of
sound (wave). Some of the parameters are common to the entire
drum instrument.
The list of Wave parameters appears when you press the [F2] (Wave)
button in the User Drum Kit Edit screen.

wave
INT: Waveforms of internal sounds

No.R
OFF, (wave
number)
Species the waveform. The wave name is also
displayed at the bottom of the screen together with
the wave number (in the case of INT, the name is not
displayed).
If you’re using mono, specify only the left (L). If you’re
using stereo, specify the right (R) as well.
* If you’re using a sample or multisample in stereo, specify the
same number for L and R.

An increase of 6 dB (decibels) doubles the gain.

VELOCITY RANGE
These settings let you play dierent waves according to your playing strength
(velocity) on the keyboard.
Velocity
Range
Lower
1–UPPER
Species the lowest playing strength that will sound
the wave.
Set this if you want to play dierent waves according
to your playing strength.
Velocity
Range
Upper
LOW-
ER–127
Species the highest playing strength that will sound
the wave.
Set this if you want to play dierent waves according
to your playing strength.
The following parameters are for the entire drum instrument, not for individual
waves
PITCH
These parameters adjust the pitch.

Tune
C-1–G9
Selects the pitch of the note that plays the drum
instrument.
* The default is 60 (C4). Edit this value if you have selected a
sample or multisample, and want it to sound at a dierent
key.

-50–+50
Pitch of the drum instrument (one cent = 1/100th of
a semitone)
TVF
The lter cuts a specic frequency region, modifying the brightness or thick-
ness of the sound.

Value Explanation
TVF Filter
Type
OFF, LPF,
BPF, HPF,
PKG, LPF2,
LPF3
Type of lter
OFF: Filter is not used
LPF: Low Pass Filter. Cuts the frequency region above
the cuto, making the sound more mellow.
BPF: Band Pass Filter. Cuts the sound, leaving only
the region near the cuto. This is useful for creating
sounds with a distinctive character.
HPF: High Pass Filter. Cuts the frequency region
below the cuto. This is useful for creating percussion
instrument sounds whose character lies in the high
frequency region.
PKG: Peaking Filter. Boosts the region of the cuto.
Using the LFO to cyclically modulate the cuto fre-
quency produces a wah eect.
LPF2: Low Pass Filter 2. This cuts the frequency region
above the cuto, but the lter sensitivity is half that
of LPF. This is useful when simulating instrumental
sounds such as acoustic piano.
LPF3: Low Pass Filter 3. This cuts the frequency region
above the cuto, but the lter sensitivity changes
depending on the cuto frequency. This is useful
when simulating acoustic instruments, but produces
a dierent nuance than LPF2 even with the same TVF
Envelope settings.
* If “LPF2” or “LPF3” are selected, the Resonance setting is
ignored.
TVF
Cuto
Frequen-
cy
0–127 Frequency at which the lter starts to apply
TVF Reso-
nance
0–127
Amount by which the sound in the region of the cuto
frequency is boosted, applying a distinctive character
to the sound
* Raising this excessively may produce oscillation, causing the
sound to distort.

TVF envelope depth
Increasing this value increases the change produced
by the TVF envelope. Negative “-” values invert the
shape of the envelope.

Increasing this value lengthens the time it takes to
reach the next cuto frequency.
