Virtual Virtuoso - Organ is a user friendly application that allows you to play the organ on your computer.
With 2 sets of designated organ sounds, you can play notes using the letters and numbers on your computer's keyboard or play sustained notes using the mouse.
There is also a button to switch from fullscreen to windowed mode to allow the user to change programs while leaving the organ running in the background. This will allow the user to record and edit their playing with Audacity or any recording software installed on their computer.
For optimal recording, you will need to set the stereo mix as your default recording device in the control panel.
