The basic system 2 comes with an A190 midi/cv interface, which is a
single-channel interface. You can use the A190 to trigger either the
A100 or the Roland, but not on two different midi channels at the same
time. If you want to do that, you should get an additional midi/cv
converter.

As far as I'm aware, you can patch the System 100 VCO right into the
Doepfer mixer, vcf, or whatever you'd like.

Hoper this helps.
