MS-20 --+-> VCO 1 CV1 | +-> VCO 2 CV1 Ribbon ---> VCO 2 CV2 Then I think the answer is here: http://www.doepfer.de/a150.htm MS-20 --+-> VCO 1 CV1 | +-> A150(1) --+ |--> VCO2 CV1 RBN CV ---> A150(2) --+ RBN GATE -> A150(CV) Basically you're using the voltage from the GATE of the ribbon controller to select between either the MS-20 or Ribbon CV controlling VCO2. If the GATE is off, then you'll get the MS-20. If the gate is ON then you'll get the Ribbon.
