Here's a little tool I have in my bag of tricks may
be of some interest, especially to 'precision'
players who want to play fast staccato passages,
or add some 'punch' in a jazz section.  Of late, I
have been using it more with the
G-snap filter to
get percussive cutoffs, emulating a "blown"
enbrochure.  It sounds more like the striking and
'roll-off' of a fingered wind instrument.

Combining the cut-off effect with exact transitions
in the 'pitch modulator' filter has some interesting
and beautiful results.  Theremin purists who
abhor the complexity of these results might
secretly try this.  Don't tell anyone that you like
what you hear!  
This is heresy.

Just tap the surface of the capacitor when it is
placed in the right spot and the volume is instantly
quenched.  Tapping the edge is "sharper" as you
contact the plates directly.
Touching the insulated
face has a  softer response.

There is no noise.  It is a simple way to abruptly add a
specific quantity to your personal capacitance.

Interestingly, this becomes part of
your contribution to
the symbiotic instrument that is a Theremin.

Placement in proximity to the expression arm
is predictably very important, but easy to
Setting the cap. on edge
makes it easier to 'tap'
the plates for fastest cut-off,

or -on, if the antenna function
is reversed.  (This is possible
with many instruments,
I believe.)

Works fine, but
might be better
if I embed a
metal stud to
link the
plates together!
Heavy-duty aluminum foil is sandwiched between insulating
plexiglas plates.  This one is glued with very thin layers of
silicone adhesive. The wood makes it more inviting to
With proper adjustments it can be a soft on,
or 'sharper' on, but not  'clicky'.  It has a
"bounce," rather than a "sudden" quality,
as you can hear.
Some discussion about employing a hand-held mute switch has come
up from time to time in the
LEVNET group, and that may be just the thing
for some.  But this elegant little gadget just might be even better.
