There will be a free reed musical instrument session, with talks and
performances, at this year's meeting by the Acoustical Society of
America (part of the American Institute of Physics, http://asa.aip.org/),
next week at the Sheridan Hilton, San Antonio. I'll be delivering a
paper on reed vibration and cavity resonance, with application to
pitch bending, at 2:30 PM, and there will be a demonstration
afterward, by Kenny Kotwitz (BluesBox), Don Mopsick (bass), and Kyle
Keening (drums). There are, of course, many other very interesting
presentations about free reed instruments scheduled.
Hi Tom,
I guess the question is: how close are you to getting this to
production? Good luck with your talk.

Hi Bob,
The talk/demo went very well, with relatively high interest.
Afterwords, Kenny and our party went nightclubbing, and Kenny sat in
with Jim Cullen's Dixiland band, playing the BluesBox, as well as
piano.
In answer to your question, my day job still seriously impedes my
aspirations for production. Thanks for the interest.
Tom

Apropos pitch bending: I am retouching a repair job with some external
advice, and in the context of reed responsiveness, I had overdone valves
pointed out to me: for one thing, the outer full-length mylar "spring"
over the vileda valve had been given a crease for pre-tensioning, for
another, the glued length of the valves to the reed blocks been
excessive. As a result, they opened with some resistance. The
recommendation was to cut down the length of the mylar spring, and to
reglue the valves with less glue after removing the old glue.
While I found that responsiveness was significantly affected only in the
worst cases (with reed closure adjustment being more important for that
purpose), the stronger valves apparently caused the pitch to bend at low
volume, making the reed pitch pressure-sensitive. Which in my preferred
musical styles is a no-no.
