Xpantastic!

Hi,

Doepfer used to have a quite interesting controller with rotary (I suppose) encoders, but it is 
not anymore available. See: http://www.doepfer.de/home_e.htm

I have got the Bitsream 3 controller:

But, I don't yet have experience on using it with Xpander. Its back and forth rotating 
potentimeters are not as good as true rotary encoders would be, however.

An other product I would consider is the Novation Remote:
