Analogue Systems, Analogue Solutions, Blacet etc modules are all
compatible in terms of interfacing with each other.
However, if you want to put them in the same case you will need
something to convert the power connectors.
I have Analogue Solutions modules in my doepfer case which only
required a different ribbon cable, easy. I have Doepfer modules in
my Analogue Systems case which required an additional circiut board
to convert plugs.
