HPF Cutoff Frequency (HPF Cutoff)
Range: –64 — +63
This determines the cutoff frequency of
the high pass filter (HPF) for the selected
drum sound. The HPF filters out frequen-
cies lower than the cutoff point and
“passes” the higher frequencies. Lower
cutoff values preserve the fundamental
and lower overtones of the sound, while
higher values create a thinner, brighter
tone. (For more information, see HPF
Cutoff Frequency on page 112.)
EQ Parameters
EQ Low Frequency (Low Freq)
Range: 32 Hz — 2.0 kHz
This determines the frequency which is
boosted or cut (in the Low Gain param-
eter below) for the selected drum sound.
EQ Low Gain
Range: –64 — +63
This determines the level of the selected
frequency (in Low Freq above). Positive
values boost the level of the selected fre-
quency and negative values attenuate it
for the selected drum sound.
EQ High Frequency (High Freq)
Range: 500 Hz — 16 kHz
This determines the frequency which is
boosted or cut (in the High Gain param-
eter below) for the selected drum sound.
EQ High Gain
Range: –64 — +63
This determines the level of the selected
frequency (in High Freq above) for the
selected drum sound. Positive values
boost the level of the selected frequency
and negative values attenuate it.
EG Parameters
EG Attack
Range: –64 — +63 (XG mode),
000 — 127 (TG300B mode)
This determines the Attack Time of the
EG (Envelope Generator), or how long it
takes for the sound of the selected drum
sound to reach full volume when a note
is played. (See page 113 for more infor-
mation about the EG function; also see
illustration below.)
EG Decay 1
Range: –64 — +63 (XG mode), 000 —
127 (TG300B mode)
This determines the Decay 1 time of the
EG, or how rapidly the sound dies down
to the Decay 2 level. (See illustration be-
low.) Higher values result in a longer
Decay time.
EG Decay 2
Range: –64 — +63 (XG mode), 000 —
127 (TG300B mode)
This determines the Decay 2 time of the EG,
or how rapidly the sound dies out com-
pletely. (See illustration below.) Higher val-
ues result in a longer Decay time.
