Creating a Rhythm Set
P-Env Level 0–4 (Pitch Envelope Level 0–4)
Specify the pitch envelope levels (Level 0–Level 4). It determines
how much the pitch changes from the reference pitch (the value set
with Coarse Tune or Fine Tune on the Pitch screen) at each point.
Positive (+) settings will cause the pitch to be higher than the
standard pitch, and negative (-) settings will cause it to be lower.
Value:
-63– +63

TVF
Filter Type
Selects the type of filter. A filter is a function that cuts off a specific
frequency band to change a sounds brightness, thickness, and other
qualities.
Value
OFF:
No filter is used.
LPF:
Low Pass Filter. This reduces the volume of all frequencies
above the cutoff frequency (Cutoff Frequency). in order to
round off, or un-brighten, the sound. This is the most common
filter used in synthesizers.
BPF:
Band Pass Filter. This leaves only the frequencies in the region
of the cutoff frequency (Cutoff Frequency), 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 cutoff frequency (Cutoff Frequency). This is suitable for
creating percussive sounds emphasizing their higher ones.
PKG:
Peaking Filter. This emphasizes the frequencies in the region
of the cutoff frequency (Cutoff Frequency). You can use this to
create wah-wah effects by employing an LFO to change the
cutoff frequency cyclically.
LPF2:
Low Pass Filter 2. Although frequency components above the
Cutoff frequency (Cutoff Frequency) are cut, the sensitivity of
this filter is half that of the LPF. This makes it a comparatively
warmer low pass filter. This filter is good for use with
simulated instrument sounds such as the acoustic piano.
LPF3:
Low Pass Filter 3. Although frequency components above the
Cutoff frequency (Cutoff Frequency) are cut, the sensitivity of
this filter changes according to the Cutoff frequency. While
this filter is also good for use with simulated acoustic
instrument sounds, the nuance it exhibits differs from that of
the LPF2, even with the same TVF Envelope settings.
If you set “LPF2” or “LPF3,” the setting for the Resonance
parameter will be ignored.
Cutoff Frequency
Selects the frequency at which the filter begins to have an effect on
the waveform’s frequency components.
Value:
0–127
With “LPF/LPF2/LPF3” selected for the Filter Type parameter,
lower cutoff frequency settings reduce a tone’s upper harmonics for
a more rounded, warmer sound. Higher settings make it sound
brighter.
If “BPF” is selected, harmonic components will change depending
on the TVF Cutoff Frequency setting. This can be useful when
creating distinctive sounds.
With “HPF” selected, higher Cutoff Frequency settings will reduce
lower harmonics to emphasize just the brighter components of the
sound.
With “PKG” selected, the harmonics to be emphasized will vary
depending on Cutoff Frequency setting.
Resonance
Emphasizes the portion of the sound in the region of the cutoff
frequency, adding character to the sound. Excessively high settings
can produce oscillation, causing the sound to distort.
Value:
0–127
