Elby Designs is working on a nice eurorack hz/volt to volt/oct and the
other way around convertor so you can interface your ms-20 and other
hz/volt gear with your doepfer system anyway you want:

give them an email, I think they are ready to get it going, they jsut
need a little push :)

I have an ms-20 too so really hoping they finish it soon.
