SAMPLE AND HOLD
The sample and
hold mixet (5/H mixei) selects
and
Mmbines sign^s to be fed to the
sample and hold carcuii.
These signals c^n
also he routed to control VCO
2
and the
VCF. Under each of
these two
funcTtions is a switch
labeled
"S/H
miKer ot pedal."
When
the foot pedal is
plugged into the
Odyssey, the
lower position of
these
switches
selects control by the pedal ;
if
the
foot
pedal is
disconnected
from the hack
of the Odyssey, the
sgine
switch
position s&lects control by the
output
of the Bfti
mixer.
The
sample
and
hoJd circuit is a controller; it is
used
only
to control MCO I, VCO
2,
andVorthe VCF. in order to
hear
what
it does listen first to VCO 2
as you
have done
before and
then
experiment with the controls

Figure W,
By "sampling" at a given
itistant
the signal voltage
from
the
S/H
nuicer, the sample and hold
cjrcuiE
produces a
series of voltage levels.
If these in
turn are used to control
a VCO, the result is a series of
pitches. The
switch under
tha sample and hold citcutt selects either the LFO
or the
keyboard
as a
triggering source.
If the keyboard is
selected
{Figure X), then a new sample
will be
talten every time
you press a key,
