If you wish to turn the vibrato effect on or
off
by
using the LFO Trigger button(3)set
these switches to OFF. If the patch (whe-
ther
preset
or you own) already contains
the
vibrato effect,
simply
press
the LFO
Trigger
button
(3),
then the vibrato is turn-
ed off and now, with this button, you can
turn
the vibrato effect on or off as you
like. The depth and rate
of
the
vibrato
effect
can be changed with the
LFO
Delay
Time or Rate knob. Also, if the LFO
Depth is set to zero, you cannot obtain
the
vibrato
effect at all by pressing the button.

waveform of
the DCO-2 will be auto-
matically sawtooth

This is the filter
to
change the tone
color
by cutting or emphasizing
harmonics. This
filter, however,
lets
the low frequency
harmonics pass and block
the high frequ-
ency harmonics, and this cutoff
point is
controlled
by voltage.
