Please try this code: ClearAll["Global`*"] notes=Table[N[(440/64)*2^((n+3)/12)],{n,60,72,1}]; Play[Sin[# 2 Pi t]&/@notes ,{t,0,.5}] Sound::ssnm: A good PlayRange could not be found since most of the samples are not evaluating to machine-size real numbers. >> I cannot understand why this er... 13 Dec 2009 05:38

unreadable text in Demonstration projects
I'm not a Mathematica user (so far), but wanted to have a look at it, so I tried to look at the Demonstration Project examples. I downloaded a random sample (EulerProductForTheZetaFunction.nbp) and installed Mathematica Player 7. Trouble is, the font in the display is far too small to read all the notation, esp... 14 Dec 2009 00:09

How to combine Dynamic graphics
From: "John Fultz" <jfultz at wolfram.com> "Show doesn't know how to deal with something that has the head Dynamic.".... Let me give a counter-example. In what follows I show a piece of code from one of my presentations, and I am much too lazy to shorten it for the purposes of demonstrating within this discus... 9 Dec 2009 06:37

SetOptions[Plot,.Z..] vs using Plot[,.Z..] behaves
This worked: VerticalSlider[Dynamic[maxy], {0.1, 4}, Appearance -> "LeftArrow"]; SetOptions["Plot", PlotRange -> {{-Pi, Pi}, {-maxy, maxy}}]; p = Dynamic[Plot[Cos[x], {x, -Pi, Pi}]]; Row[{ver, p}] On Sat, Dec 5, 2009 at 6:35 AM, Nasser M.

SetOptions[Plot, .Z..] vs using Plot[, .Z..] behaves differently when Z is Dynamics
This isn't a problem with Dynamic at all. If you cleared maxy beforehand, it would have worked. Take a look at the SetOptions command. You're not using RuleDelayed! Any previous assignment of maxy is going to be dropped literally into the option, rather than the symbol 'maxy'. Your attempted explanation wou... 6 Dec 2009 02:01
