E ach time KE Y1 is triggered, the corre-
sponding group is played in sequence. When
the last group is finished the K E Y1 group
sequence will be repeated by successive trig-
ger inputs.
K E Y1 as a two-group key (TWIN mode).
K E Y1 can play two groups, if K E Y1 is held
down, the group 1 can be played repeatedly
till KE Y1 is released, and immediately then
the group 2 will be played one cycle by the
rising edge of K E Y1. (see Figure 1)
Key operation functions
KE Y1~KE Y8 all function as trigger keys. By
mask option, the HT812L0 provides three trig-
ger functions for the 8 keys , namely: “one shot”,
“l(fā)evel hold” and “l(fā)evel trigger”. All of the three
trigger functions can be optioned as retrigger-
able or non-retriggerable.
Trigger function
One shot
When one of the 8 keys (KE Y1~K E Y8) is
pressed and held down, or pressed momen-
tarily, the group corresponding to that held
or pressed key will play once.
Level hold
When one of the 8 keys is triggered, the
group corresponding to the triggered key
will keep playing till that key is released.
Level trigger
When one of the 8 keys is pressed and held
down, the corresponding group will keep
playing. Once the pressed key is released,
the group will not stop till the included sec-
tions are all completed.
