media: vidtv: fix some notes at the tone generator
The sheet music used to generate the tones had a few
polyphonic notes. Due to that, its conversion to a
tones sequence had a few errors.
Also, due to a bug at the tone generator, it was missing
the pause at the initial compass.
Fix them.
While here, reduce the compass to 100bpm.
The music was converted from a Music XML file using
this small script:
<snip>
my $count = 0;
my $silent = 0;
my $note;
my $octave;
print "\t";
while (<>) {
$note = $1 if (m,\<step\>(.*)\</step\>,);
$octave = "_$1" if (m,\<octave\>(.*)\</octave\>,);
if (m,\<alter\>1\</alter\>,) {
$note .= "S";
$sharp = 1;
}
if (m,\<rest/\>,) {
$note = "SILENT";
$silent = 1;
}
if (m,\<duration\>(.*)\</duration\>,) {
printf "{ NOTE_${note}${octave}, %d},", $1 * 128 / 480;
$count++;
if ($silent || $count >= 3) {
print "\n\t";
$count = 0;
$silent = 0;
} else {
print " ";
print " " if (!$sharp);
}
$sharp = 0;
$note = "";
$octave = "";
};
};
print "\n";
</snip>
