VCV CV>MIDI vs RackCore CV>MIDI

Good evening,

I’m trying to use MM usb midi input/output.
I have a generic usb midi interface cable attached to usb c on MM.

I’m using XOX drum machine v2 for midi input on ch10 - no problem - working fine.
I also want to send midi channels 11, 12, and 13 through MM from my keystep pro to go midi out via same usb interface. I want to add a midi skip like a chances or bernoulli gate for each of those midi channels (neutron, k2 and model d all live in my rack). For a test - I tried using vcv midi>cv with chances and cv>midi for ch 12. It didn’t work.
Digging a little it looks like I have to use rackcore modules inside mm, which I tried and does work… but is a pita to edit.
Are rackcore modules available for VCV rack?
Should I be able to accomplish this in VCV rack?
Thanks

I’m interested in this as well, but have an added question.

I looked on the website and it appears there are various rack core modules built-in, but I wasn’t seeing some of them on my Meta. Which are supposed to be there, is there a list, and if they’re missing, how do we get them onto the meta?
