MULTI MODE
EQ High Gain
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.
Range: –64 — +63
EG Attack
Range: –64 — +63 (XG mode),
000 — 127 (TG300B or C/M 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 52 for more in-
formation about the EG function; also see illustration below.)
EG Decay 1
Range: –64 — +63 (XG mode),
000 — 127 (TG300B or C/M mode)
This determines the Decay 1 time of the EG, or how rapidly the
sound dies down to the Decay 2 level. (See illustration below.)
Higher values result in a longer Decay time.
EG Decay 2
Range: –64 — +63 (XG mode),
000 — 127 (TG300B or C/M mode)
This determines the Decay 2 time of the EG, or how rapidly the
sound dies out completely. (See illustration below.) Higher values
result in a longer Decay time.

Time
Alternate Group
Settings: off, 001 — 127
This determines the group assignment of the selected drum sound.
Drums assigned to the same group cannot be sounded simultane-
ously. In other words, if one drum in a group is sounding while a
second in the same group is played, the first drum sound will be cut
off and the second will sound.
