Have a look at
  http://www.doepfer.de/a110_tec.htm
though there is no description in the text, you can see the features and 
how to connect them in the schematic.

The main advantage of the linear-FM on the A110 is the possibility to 
bypass the input capacitor -  i.o.w.: DC-coupled FM. This is very(!) 
useful with the theremin controller, but also with other continuous sources.
