If you enter a value and click OK, that value is applied. That is
what I want to do. I first try without the OK button, but the result
was erratic and uncontrollable.

Strange, it run fine here, both with the alsasink and the
jackaudiosink. I will compare the 2 versions.

Just because I didn't know it before.

OK, I will change that. With the actual code, the precision of the
frequency changes with the buttons is not as great than the ones I get
with bc into a shell script (used to control alsaplayer and mplayer
speed). I am sure using a float will improve that.

You made huge change to the menu. I will take a look at it later.

I know. Gambas is not that hard, but it is complex. This is the same
issue with fvwm, which is not only a wm but also a tool-kit for the
Xlib at the same time. And I think that like with fvwm, each piece of
Gambas have its place, and it will take me some time to get the big
picture.

Thank you for the review,
Dominique
