In addition, a section can be set as retriggerable
or non-retriggerable depending on the code op-
tion.
Retriggerable
When the currently playing section is set as
retriggerable, it will be stopped immediately
upon receipt of other key inputs.
Non-retriggerable
When the currently playing section is selected
as non-retriggerable, it will go on playing till
the whole section is completed, whether or not
there is a key input in the process of playing.
For a key group, some sections can be set as
retriggerable and some as non-retriggerable.
When a retriggerable section of a key group is
playing, any key can be input to interrupt its
playing.
On
the
non-retriggerable section is playing, any key

Group
The HT818D0 plays according to the basis of
the key input. Agroup can be made up of one or
more sections. When a key is triggered, the cor-
responding group is played immediately. For
example, triggering KEY2 plays group 2, and so
on. The same section is allowed to appear in dif-
ferent groups. However, KEY1 can be made up
of multiple groups when it is optioned as a se-
quential or random key. Otherwise, each key is
composed of one group only.
Key function table
The sections included in the voice ROM are
played according to the instructions of the key
function table. The function table contains
group information and the playing order of sec-
tions in the groups. Notice that the total num-
ber of sections included in the groups should be
less than 508 the space limitation of the func-
tion table ROM.
KEY1 as a direct key
Each key is mapped to a group in the
function table. If a key is not used, the group
mapped to that key is a piece of silence.
Thefollowingisanexampleofthefunctionta-
ble:
Group 1
sec.1 + sec.2 + sec.3 + sec.5
Group 2
sec.3
Group 3
sec.2 + sec.2 + sec.3 + sec.4
Group 4
sec.5 + sec.3
As illustrated in the above table, the voice
ROM is composed of 5 sections and the func-
tion table of 11 sections. If KEY1 is momen-
tarily triggered, section 1, section 2, section 3
and section 5 are played in sequence and then
stops. Triggering KEY2 plays section 3, and
so on.
KEY1 as a sequential or random key
WhenKEY1isoptionedasasequentialorran-
dom key, it can include multiple groups
(sub-groups) in the function table. However,
the remaining 11 keys (KEY2~KEY12) are used
as direct keys exclusively and comprise only
one group in the function table.
An example is shown below:
Group 1-1 sec.4 + sec.2
Group 1-2 sec.1 + sec.3
:
:
:
:
Group1-N sec.2 + sec.3
Group 2
sec.2 + sec.3
Group 3
sec.3 + sec.5
Group 4
sec.1 + sec.5 + sec.2
As indicated in the above table, KEY1 can be
made up of sub-groups. Each time KEY1 is
triggered, the corresponding sub-groups are
played in sequence.
The playing sequence of sequential KEY1 is:
Group 1-1
Group 1-2
Group 1-N (the last group)
The playing sequence of random KEY1 is:
Group 1-3
Group 1-5
Group 1-3
Group 1-5 .....
Group 1-3 .....
Group 1-1 .....
Group 1-N
