Thanks, Mark.  If the proposal gets approved, I'll be in touch.

  Barbara, Bill,

  Sorry Bill, I'm not a big fan of the carts either.=20

  They are removed from the piano at precisely the time I don't want =
"anything" changing around the piano.=20

  We do use them in Banff, but only in the Rolston Recital Hall, and =
only (I believe) because this is one hall where ambient conditions are =
indeed monitored and controlled.=20

  I've encountered mold in only one instance Bill (sorry to hear of your =
experiences); a new-to-me client with an 1970's L: the tank was plugged =
directly into the wall... as in bypass the humidistat!  (need I say =
more?)=20

  I'm not sure of the material Bill refers to Barbara, but the cloth =
Dampp-Chaser's under-covers are made from will not absorb sound, they're =
acoustic grille cloth. For all practical purposes: acoustic impact =3D =
zero.

  So I will vote for an installed system with undercover.=20

  The first benefit being to buffer the piano's climate from changes and =
high air-movement within the hall. =20
    =20
  The second really, is to nicely hide the installation. Even if there =
is the odd wrinkle or bulge in the cloth, from the front row the =
underside of the piano looks like a "sea of black."

  We've installed a few Barbara, so if I can provide any install tips; =
cramer@brandonu.ca

  Meanwhile, something the two of you (and others?) may be interested in =
as well:

  I've just installed an "un-plug" alarm in one of our ensemble rooms.

  Un-plug the piano, and a concealed beeper sounds until the piano is =
plugged back in.=20

  So far so good. I've posted instructions (that even music students can =
read), the piano has been moved, and the "movee" figured out the =
"prompt" immediately.

  Sorry I cannot provide mechanical details, as one of our engineers =
devised it. Basically it's a relay with a 9v batter and a pulse beeper.=20

  best regards to you both,
  Mark Cramer,
  Brandon University

    Hi, Barbara,=20

    My experience with buckets tight up to the soundboard is that the =
board discolors, mold develops, and condensation causes hardwood floors =
to betray water overhead.....Don't ask me how I know...but shortly after =
that nasty experience several years ago Damppchaser extended the hanger =
length considerably. =20

    A cover under the piano will certainly affect the reflection of =
sound...but there are probably folks on the list who could tell you how =
much, in their own experience....I'm interested too!  =20

    Just to go with my "cart" idea again....the cart can be kept under =
the piano on stage, and removed just for performances, of course....

    OR....the piano can be equipped with heater bars and humidistat, and =
the cart only with humidifiers, and used as much as possible.  =20

      Thanks, Bill.

      Hmm....my goal was a system that could always be plugged in (there =
are a lot of outlets on that black stage floor), to avoid the syndrome =
of nice-atmosphere-while-in-storage and then all heck breaks out when =
it's moved on stage.  You know what I mean?

          Hi all,

          Does anyone have a picture of, or could direct me to a picture =
of a Steinway D with a full DC system with undercover--preferably on a =
stage?   I have submitted a proposal for the DC system, but a friend =
pointed out to me, that sometimes, because the humidifier buckets hang =
down a bit, the piano looks.........pregnant.   I doubt my technical =
director would be happy with such a look and would like him to see it =
before hand.

          Thanks much.

          Barbara Richmond, RPT
        Barbara, If you could forego the undercover, you could modify =
the Jahn stands which Dampp-chaser is experimenting with.  They are =
single system carts with a leg on each corner, and need to be combined =
into a dual system stand which straddles the truck;   I did this during =
the summer, and will be sending Roger Wheelock the modification drawings =
when I "get it together."  =20
