The oscillator is turned on when triggered by a
key input. After playing, it is turned off and the
chip goes into the standby state.
Voice ROM
The voice ROM is originally designed to continu-
ously record the 8.4-second voice data at a 6kHz
samplingrate.Ahighersamplingratewillgener-
ate voices of better playback quality, but will
shorten the total recording time. On the other
hand, a lower sampling rate will result in longer
recording time but sacrifice voice quality.
The playback time can be significantly extended
by making use of coding efficiency, silence play-
ing, section repeating, section cascade.
Section
Section is the basic element constituting the
contents of voice ROM. During programming,
the customer s voice sources can be divided into
as many sections as required. A section can be
composed of a voice or an interval of silence.
However, the silence length is not counted in
the voice ROM. The total number of sections in-
cluded should be less than 508 due to the space
limitation of the function table ROM. The total
length of the included sections is limited by the
voice ROM.
Asection, when triggered by a key input, can be
played once, repeatedly or cascaded with other
sections, depending on the key function table
instructions.
The following are examples of section division:
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 stop 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 triggered to interrupt
its playing. On the other hand, if a
non-retriggerablesectionisplaying,anykeyin-
terrupt is invalid.
