Doepfer

I have a quick question. Using Doepfer modules, is there a way to get the MS-20 mini’s (Hz / Volt) output to scale correctly in order to control Doepfer oscillators? I had a Harvestman English Tear but it was a nightmare to set up properly. In my head this should be possible as it’s a question of scaling but whatever I try it doesn’t quite work.

Any help would be awesome :)
