Which Edition of Hauptwerk should I choose?

 You can find Hauptwerk's own explanation of the features for each edition here.

Other considerations:

• Do you plan to play organs with over 20 stops?
• Do you want to use more than stereo speakers and a subwoofer?
• Do you want to be able to adjust the sound of ranks or individual pipes?

If you answered "yes' to any of the above questions, you should purchase the Advanced Edition. Otherwise you can use the Basic Edition.
