hello,

you'd also need:

another xtreme filter (you need two to replicate the ms20)
another vca (for example the lowcost dual vca)
a slew limiter for portamento (if you take the a170 maybe
you can omit one adsr envelope, as the lower half of the a170
can be used as a simple envelope too.)

best wishes

ingo
