Digital Controlled Amplifiers
(DCA
1,
DCA
2)
The Digital Controlled Amplifiers
correspond
to
the
VCA
(Voltage
Controlled Amplifier)
in an
analog
synthesizer. As parameters,
the DCAs use
Key Follow
and Envelope
Generator
parameters.
Key Follow
controls the
duration of
the envelope's effect
according to
the pitch
of the keys
be-
ing played,
while the Envelope
parameters
control the change
in volume
over time
when
a
key
is being
pressed.
The
Key
Follow
parameter
has the function of shortening
the
duration of the envelope
the higher
the pitch of the key being
played. This is very
practical when
you want
to
create
the sounds
of instruments
such
as
piano
or guitar (where strings are hit
or plucked) since
the
duration
of their
sounds decreases the higher
the pitch.
(See Fig.
1.)

The change of volume (amplitude)
over time is controlled
by the envelope
generator.
This
means that the volume
changes according
to
the rate (slope) and
level (final level in
a
step)
that have been set.

Detune
This function detunes (alters)
the pitch
of Line
H]
or Line!2], outputting their sounds as
Line
DC
and Line
[2]
respectively. The detuning amount can
be
set
freely
in
the range between
1.7 cents
(1/60
of
a
half-tone) and about 4 octaves both upward and downward.
