that is, to put it simply, to make a volume control
I tried to do this

begin
  MusicObj.SetVolume(VolTrackbar.GetValue);
end;

Inno says... not right
thank you in advance.

procedure Trackbar1OnChange(Sender: TObject);
begin
  MusicObj.SetVolume(Round(Trackbar_Regular.GetValue));
end;

but why?

IXBass :
procedure SetVolume(Const Vol: Integer);


FTrackBar :
function GetValue: Single;
