Hi Lee S

It�s one of the old CD line Wersi cabinets with all the Wersi innards and panels removed.

The lower keyboard is a cannibalized M Audio which he has adapted to suit the casing. (The buttons and Slider are a standard fit on the M Audio Controller)

He is very active on the Tastenpoint Forum http://www.tastenpoint.at/forum/ which if you use Google Translate you will get by fine. (Reply in English as he also uses Translation Software)

There is also a link to a video on the site that actually shows you the innards and how it is made up.

Hope this helps

Bill
