jOrgan- runs in Java on your Windows or Linux PC!

With jOrgan you can use your computer as a virtual organ. I haven't spent much time with this program yet, but have had the classical and theatre organs running. It looks like a great program. What I really like is the versatility of design. It looks like the sky is the limit as to organs you can build. It is definitely worth a good long look at!

Did I mention that it is freeware?

The hardware-requirements are:

• a computer running one of the major Operation Systems: Windows, Linux or Mac,
• external MIDI keyboard(s) and/or controller(s) such as Digital Piano, Synthesizer, MIDI-control-box, MIDI-ficated acoustic piano/keyboard/pedals.
• MIDI cable and MIDI adapter
• MIDI input device for your computer like a PC soundcard or a USB-MIDI interface).
• MIDI output device(s) (PC Soundcard, Expander, Hardware/Software Sampler).

Here is a screenshot of jOrgan showing how an organ can be constructed. This is the "classical" skin. Also available are the "theatre" and "Hammond" skins.

With jOrgan you can construct any keyboard based instrument (as long as you have the required hardware to play and control it) - pipe organs, theatre organs or harpsichords. Note that jOrgan does not produce sounds itself, it's depending on other sound producers (software or hardware) which can be controlled via MIDI.
