Like it - even if beep don't give sound on my system Very Happy

If you would like to consider it, I have rearranged your code. Just to give an example of another coding structure. Thomas-Virtual-Piano.sh has gone from 224 to 68 codelines, and the gui is more compact. - Narrower, but with the same key-size.

Code:
#!/bin/bash
WHEREAMI="$(cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd && echo)"
cd $WHEREAMI

build_key (){
   SOUND=$(cut -d_ -f1 <<< "$1")
   COLOR=$(cut -d_ -f2 <<< "$1")
   echo '<vbox>
     <pixmap><input file>'$2'.png</input></pixmap>
      <button relief="2">
        <action>"beep -f '$SOUND'"</action>
        <input file>"key'$COLOR'.png"</input>
      </button>
   </vbox>'
}
export -f build_key

export DIALOG='
<window resizable="false" title="Thomas Virtual Piano" image-name="Thomas-Virtual-Piano.png">
  <vbox>
    <hbox>
      <pixmap>
        <input file>speaker.png</input>
      </pixmap>
      <button ok></button>
      <button>
        <label>"About"</label>
        <action>"'$WHEREAMI'/about.sh"</action>
      </button>
      <hbox scrollable="true" width-request="10" height="30" >
        <pixmap>
          <input file>bar.png</input>
        </pixmap>
      </hbox>
      <button>
        <action>"beep -f 300 -l 40 -n -f 400 -l 5 -n -f 250 -l 15 -n -f 100 -l 10"</action>
        <input file>"cymbal.png"</input>
      </button>
      <button>
        <action>"beep -f 300 -l 40 -n -f 400 -l 5 -n -f 300 -l 10"</action>
        <input file>"hithat.png"</input>
      </button>

This would be a nice musical app for a touch-screen PC. Would be nice if it came with distro's Menu>Games folder, as, say "20key Piano" I will try it, later.

Question
As it currently is 20keys, is the number of keys selectable; say, 44keys or 88keys for large touch screens?

There are other ways to generate a beep noise like the command speaker-test
Code:
speaker-test -c2 -t sine

Quote:


You might look at speaker-test, which (on an Arch machine) I find in alsa-utils package.

speaker-test -c2 -t sine run from an xterm, gave me a 440 Hz sine wave for about 6 seconds each, alternating left and right speakers. In the xterm, it gave some information about which speaker it thought it was using.

According to the man page, it can do sine waves of arbitrary frequency and pink noise.
