De D9-X van Crumar is een compacte drawbar controller die via USB communiceert met onder andere de elektrische orgels

Crumar D9-X Drawbar ControllerThe D9X is designed to work with the GSi VB3-II, but not ALL functions are working (strange), probably is this solvable using the software you can download. When you use it on another organ (e.g. UA Waterfall B3) there are many more functions not working.
So the this is no 'solve all soluition' for all virtual organs.
