Hi Jed,
I wouldn't say you need it as you can feed the audio out from MS20
to the doepfer VCF fine, the level isn't very loud but not too
quiet, close to the noise barrier though.
If you're planning on doing it alot then I'd recomend the a119 as it
makes the sound very loud and clean.
CV in and outs are no problem.
Also if you're planning on playing or triggering the a100 from the
MS20 keyboard you'll need the a165 (trigger modifier) module to
invert the signal)


John.
