For a key group, some sections can be set as
retriggerable and some as non-retriggerable. When a
retriggerablesectionofakeygroupisplaying,anykey
can be triggered to interrupt its playing. If it is a
non-retriggerable section playing, any key interrupt is
invalid.
Group
The EasyVoice
TM
plays groups according to the key in-
put. A group can be made up of one or more sections.
When a key is triggered, the corresponding group is
played. 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 multi-
ple groups when it is optioned as a sequential key.
Otherwise, each key is composed by one group only.
Key Function Table
The voice ROM sections are played according to the in-
structions of the key function table. The function table
contains group information and the playing order of the
sections in the groups. Notice that the total amount of
sections included in the groups should be less than 256
which is the space limitation of the function 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. The following is an example of the
function table:
Group 1
sec.1 + sec.2 + sec.3 + sec.4
Group 2
sec.3
Asillustratedinthetable,voiceROMiscomposedof4
sections, and 5 sections for the function table. If KEY1
is momentarily triggered, section 1, section 2, section
3 and section 4 are played in sequence and then
stopped. Triggering KEY2 plays section 3.
KEY1 as a sequential key
When KEY1 is optioned as a sequential key, it can in-
clude multiple groups (sub-groups) in the function ta-
ble. However, KEY2 is used as a direct key exclusively
and comprise of 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
:
:
:
:
Group 1-N
sec.2 + sec.3
Group 2
sec.2 + sec.3
Asindicatedintheabovetable,KEY1canbemadeup
of sub-groups. The corresponding sub-groups is
played in sequence each time KEY1 is triggered.
The playing sequence of sequential KEY1 is:
Group 1-1
Group 1-2
Group 1-3 .....
Group
1-N (the last group)
Group 1-1 .....
Reset of KEY1 playing sequence
If a sub-group of KEY1 group is being played and
KEY2 is triggered, the playing sub-group will be ter-
minated,andthenewlytriggeredkeygroupisplayed
in stead. The first sub-group will start playing by
retriggering KEY1. In other words, the KEY1 playing
sequence is reset whenever a key other than KEY1
is triggered (see Figure 1).
Sub-group selection
When KEY1 is triggered with pulses, a desired
sub-group can be selected by controlling its corre-
sponding pulse number. However, the features of
KEY1 have to be set in the following ways:
Sequential
Retriggerable
Minimumkeydebouncetime( 1.2ms,f
OSC
=2MHz)
For instance, if sub-group 1-3 is the previous playing
group, sub-group 1-5 will start playing after 2 pulses
are applied to KEY1, and so on.
To make a selection of KEY1 sub-groups more easy,
KEY2shouldbeprogrammedassilence.Thenthissi-
lencekeyhastobetriggeredtoresetKEY1.Bysodo-
ing, the playing sub-group of KEY1 is directly
specified by the pulse number applied to KEY1 (see
Figure 2).
