I have just used Polyphone to create a new .sf2 soundfont for the Barton 3-7 organ. This is a proper fully featured theatre organ and is designed to be played using my organ which is eplayOrgan. Just google it to find my website where you can download and use the organ completely free. This sound font sounds pretty much exactly the same as the real Barton organ (Available for Grande Orgue).
The sound font is free but is too large to be stored in my free account on this site. However if you contact me by email I will arrange for you to download it.
