Drone
This is a fun setup for modal
jams or morning ragas – it
uses just the sound of the
VCO set to one frequency,
tuned to the key that you’re
playing in. If you’re in A,
just tune the VCO to A with
the Freq control. The drone
sound can be fattened up if
detuned a little bit from a
bass note in the key. Setting
the Mix control is important
for a nice balance between
the instrument sound and
the VCO sound.
Foot Theremin
This is basically the same
as the previous setup with
the addition of an expression
pedal to control the VCO
frequency. It’s difcult to
control the frequency of
the VCO precisely with an
expression pedal, but quite
fun to attempt. Try playing
staccato for synth-like bleeps
and bloops, or play sustained
tones with wild expression
pedal movements for instant
psychedelic freakout sounds
a la the "Whole Lotta Love"
breakdown (just add a little
echo).
