Hello,

I don't have access to the schematics of the DE's, but it should be 
possible basically.

You have to pick the voltage from the slider contact of the tuning 
potentiometer of DE1 and feed it to an additional socket on the DE1

In the DE2 you have to add a socket and a resistor. The resistor is a 
duplicate of the existing resistor that is connected already to the 
existing tune potentiometer (there is a tune range Jumper too, which may 
hav to be obeyed). The socket feeds this additional resistor.

Now you have to connect the two sockets with an patch cable. DE1 will be 
the master tune. On DE2 you still can adjust the offset tuning.


To get an idea of it, have a look at the schematic of the A-110 
http://www.doepfer.de/a110_s.gif
On the left you find the existing tune-potentiometer (P1). R5 (right to 
it) is the existing resistor.
The additional socket and resistor will look like BU2 and R6 (don't obey 
the given values and the connection to "int.cv" !).


For the exact values of the resistors and for the places on the pcb 
access to the schematics would be required. (Dieter?)

Florian
