Thanks for your enthusiasm, we hope you enjoy the new edition of Hauptwerk.
One of the things which put me off was the lack of fairly basic information on the site. The only instructions were about downloading and installing, with nothing about midi connections, sound cards, and other similar issues.
The same information contained within Hauptwerk is also listed on the website and in the evaluation versions of Hauptwerk.
There are many pages in the Hauptwerk user guide about sound cards and other recommendations for how to use Hauptwerk. Please see the support section of the site as listed here:

Also on the requirements page are 2 extractions from the user guide which list many of the technical details about computers and other hardware.
