Hello Paul, I had a try with the slider, but it bugs and blocks. This is due to a misuse of get() in slider_update() and in play(): get() is built to get the value of a given property from a given (or current) object. It does not aim to get the handle of an object according the value of one of its properties. This is the findobj() role. When in both functions findobj() is properly used instead of get(), all becomes OK: function y = slider_update(x) //sl = get("slider"); // NOK sl = findobj("tag","slider"); value = get(sl, "value"); // OK ... function play(y, rate) updateStatusBar(" Playing the sound..."); //sl = get("slider"); // NOK sl = findobj("tag", "slider"); I guess the same fix shall be applied to other scripts. Regards Samuel

I tried with 6.0.0 and 6.0.x NB 64 bits on Win7, since you specify "Requires Scilab 6.0.0 or above". It works for a short series of updates, and then blocks, and even sometimes crashes (mainly when dragging the slider instead of clicking on a side). Then, just after closing the slider widget, the following error message is displayed, apparently as many times as there were uneffective updates (clicks) before closing: get : Type erroné de l'argument n°1 : Un réel attendu. à la ligne 3 de la fonction slider_update ( C:\Users\Samuel\Desktop\Musical_demos6\demo_slider.sce ligne 62 ) A very strange message, since no syntax with argin#1 as a real is documented for get(). Moreover, the syntax h = get("handlePath") is not documented. But after some additional tests to go on the discussion http://mailinglists.scilab.org/Users-fr-findobj-tt4036787.html, it actually works. I have reported the lack of doc: http://bugzilla.scilab.org/15226. Regards Samuel

The only accepted number is 0, to target the console.
