Oscillator
Synchronization
In
the
Sync
Mode
Oscillator
2's
sawtooth
wave
can
be
reset
by
itself
or
by
the
reset
pulse
from
Oscillator
1.
This
locks
the
fundamental
frequency
of
Oscillator
2
to
Oscillator
1,
generating
a
complex
waveform.
In
the
"Contoured"
sync
mode,
control
voltage
from
the
contour
generator
is
routed
only
to
Oscillator
2.

Mixer
When

are
set
at
5 or
higher,
the
Oscillators
over
drive
the
filter
input,
producing
a
small
amount
of
intermodulation
distortion
-
the
