Yep, the 'Durian' concert hall in Singapore, for instance, has an organ with an additional wireless console, which can be moved to wherever is most convenient.

Yep, the 'Durian' concert hall in Singapore, for instance, has an organ with an additional wireless console, which can be moved to wherever is most convenient. I was there as the German organ builders responsible for it were putting on the finishing touches. What interests me about the organ in the clip is that the music, "putting on the ritz", has been slowed down. That implies that the mechanical pipe switching system must be a bit slow. Given that this guy did the whole thing largely from first principles, neither of the above are meant as a criticism; it's a brilliant project!
