PARAMETER
TABLE
DCO
(Digitally
Controlled
Osclliator)
DCO
is
the
digitally
controlled
oscillator
that
con-
trols
the
pitch
and generates the
waveforms
that are
the
sound
source of the synthesizers.
Owing
to
its
digitally controlled
system,
this
offers superior
pitch stability
compared
with the
VCO
(Voltage
Controlled
Oscillator).
The
JX-10 has 2 DCO's.
