Plonk Manual
v1.01
In
AR
mode
the
envelope
simply
goes
through
the
attack
and
release
stages.
This
is
suitable
for
most
percussive
sounds.
In
AHR
mode
an
additional
hold
stage
is
added
which
keeps
the
envelope
high
for
as
long
a
gate
is
applied
at
the
TRIG
input.
This
is
useful
for
articulated
sounds
such
as
sustained
basses,
effects,
or
dynamic
percussion
sounds
such
as
open
high
hats
where
you
want
to
vary
the
length
of
the
sound.
Object
Parameters
The
resonator
parameters
menu
is
accessed
by
pushing
the
OBJECT
button.
In
Plonk,
sounds
are
produced
by
feeding
the
output
of
the
Exciter
into
an
acoustic
object
model
called
a
resonator.
Mathematically,
a
complex
sound
can
be
decomposed
into
elementary
components
called
partials
.
The
relative
frequencies
of
the
partials
are
specific
to
the
type
of
object:
the
partials
of
a
string
will
follow
the
ideal
harmonic
series,
while
those
of
a
drumhead
will
be
bunched
closer
together.
The
material
of
the
resonator
will
have
an
effect
on
the
relative
decay
of
the
partials,
while
the
position
at
which
it
is
excited
will
have
an
effect
on
the
relative
amplitude
of
the
partials.
The
resonator
section
also
includes
an
embedded
envelope
generator
that
can
be
used
to
change
the
pitch
during
sound
playback.
The
envelope
is
a
simple
linear
envelope
triggered
each
time
the
exciter
is
triggered.
Resonator
Type
Selects
from
one
of
the
six
resonator
types:
●
String
–
a
plain
string.
Good
for
plucked
or
bowed
sounds.
●
Beam
–
a
rectangular
beam
with
constant
cross-section.
Good
for
bells,
chimes,
claves,
woodblocks
and
other
small
percussions.
●
Marimba
–
a
beam
with
variable
cross-section,
producing
more
harmonic
overtones.
Good
for
chromatic
percussions
like
marimbas
and
vibraphones.
●
Drumhead
–
circular
membrane.
Good
for
various
drum
sounds.
●
Membrane
–
rectangular
membrane.
Good
for
various
drum
sounds.
More
dissonant
than
the
drumhead
resonator.
●
Plate
–
rectangular
plate.
Good
for
cymbals,
gongs,
bells
and
other
metallic
or
wooden
percussions.
