Random voltages can produce interesting effects in a synthesizer.
Traditionally, this is created by a circuit called “sample and
hold” or “S&H”. In a sample and hold circuit, a voltage is sampled
from noise and sent to affect another circuit. There is no telling
which voltage will be sampled!

You can recreate this with
your voice. Try making an
“Ah” sound and then slowly
shift to an “Ooh” sound.
Your mouth creates a filter
that changes the timbre of
the sound much like the filter.
• The filter is known as a low-pass filter.
This means that frequencies higher than a
certain point will be reduced or filtered out.
• When the peak is increased and the cutoff is
adjusted, the timbral effect can sound like a
person making vowel like sounds.

The filter is based on
KORG’s famous MS-20 design.
