THE
BASIC
CONCEPT
OF
A TONE
A
Tone
consists of
two
Partials (Partials
1
and
2)
and
a
Common
block.

Each
Partial (Partial
1
and
Partial
2)
can have one
of
two sound
generators
(a
Synthesizer
sound
source or
a
PCM
sound
source).
So
you can
think
of
the
D-50
having powerful
synthesizers
built
in.
Each
of
these
hypothetical
synthesizers could behave
like
a
conventional analog synthesizer, or
a
PCM
sampled
synthesizer.
Any
combination
of
two synthesizers can
achieve
some
remarkable
cross
—
modulation
effects,
so characteristic
of today's purely
digital
sounds.
Some Common
parameters apply
to
both
Partials
(Partial
1
and
2),
"Structure"
is
one
of the
Common
parameters.
It
decides
which
of
the
two sound
generators
is
used
for each
Partial.
Other
Common
parameters
are
an
ENV
for pitch, three
LFO
modules,
equalizer,
chorus,
etc.
