LOW FREQUENCY OSCILLATOR PITCH BEND CONTROL
The LFOon yoijt ODYSSEY^ as^ycti have alfead/ seen,
is used to
Cfeate voltages which
produc*
vibrato,
tfiJl,
tremolo, and
other effects
when these voltages
are
applied
to the VCO or VCF. The LFO produces both a -sinew^ve
output
^nd a ^uare wave outpLit, Ths ^inewave output ts
used to create vibrato and tremolo effects and the
square
wave is used to cieate trills. The LFO is also hooked up to
the ADSR
ENVELOPE
GENERATOR, via
the REPEAT
SWITCHES.

The
Pitch
Bend
knob
is a live performance control for
bending notes, It also e-xtends ths tuning irange up
to
art
e^rtrai octave beyond
rtOfmaL This control permits
you to
realisticaltiT "bend" pitches in order to recreate the kinds
of effects and create sounds th^t are not imitative of
traditional instruments.
When recreating
the effect
of
the
pitch
bend of traditional
instruments, however, limit the
pitch deviation
to
approximately
one half-step, This is the most useful and
oonamon
effect employed
by
guitarists,
including those
who work with rock groups. Notice that the
normal
position
tot the
pitch
bend knob is in the center of a
"dead zone" where turning the
knob
stightly either way
results in Lttle or
no
pitch
change. This
feature lets
you
"feel" the normal position while playing, without
having
to
ICNok,
at
the
panel.
By taking
advantage of the
fact that the range of this now
is exactly up or dovm an octave^ you
can use
the PITCH
BEND
CONTROL as an auxiliary TRANSPOSE switch, or
you
can
u^
it
as a
guitar "string
pull" effect with a haid
5top wrfien the instrument is exactly in
tune
by
turning [he
switch aU the way to the left and playing an octave higher.
This
is
very
similar
to
a 'Tremolo Bar" on a guitar, although
on both instrun>ents
actual
change
is
in frequency,
