SUMMARY: The 30-stop English romantic organ recorded from St. Anne's, Moseley in Birmingham, England shows the many features that Hauptwerk Virtual Pipe Organ is capable of, including expression, tremulants, crescendo, bass and melody couplers as well as a fully working combination system identical to the original organ. This virtual instrument is included and installed automatically with Hauptwerk; you can download a demo version and try it for 30 days: https://www.hauptwerk.com .
THE LAYOUT: the layout is aimed to control the organ console from MD; the midi-learn function of the Hauptwerk organ makes the setup very easy and quick.
The layout's "stop" buttons (the round buttons) receive midi messages from the organ, so if you connect the midi-out of your computer to the MD's midi-in, when you push a "combination" button (hexagonal buttons) the layout is immediately updated with the organ interface.
I have done also a layout for the iPhone (only combinations' buttons).
