This web site describes a digital organ based on a PC. It is a very cheap way to put together an organ that will sound better (in the software author's opinion!) than any analog organ, and as good as many of the cheaper digitals. If you enjoy tinkering with things, this is for you. It provides a completely satisfactory practice instrument. When this idea was developed, there was very little else around. Now there are several programs, with nicely designed interfaces etc. The main advantage of this project is that you can do almost anything you want, without the need for programming skills.

It sounds like a program with possibilities, however I have not tinkered with it at all.

There are several pipe organ soundfonts. The best one to start with is Jeux1.4 by John McCoy. This is available at the Hammersound website. www.hammersound.net.

There is also "Pfeifenorgel", by Andreas Sims Andreas.Sims@t-online.de This sound font costs about thirty-five dollars. There is Bruce Miles English Church Organ sound font. There are also  other soundfonts available for the theater/cinema organ. Many of these soundfonts are available at Hammersound.

Jeux d'orgues 2.1 by Joseph Basquin is another great Sound Font (Have fun, the site is in French)!
