How do I remotely change the arpegiator for a given instrument?

Ok, I found what the problem is with arp (in my case). I use small USB keyboards with almost only keys. But it's great keyboard and very useful for bass/strings section (with arp). There are no any additional encoders/keys which could be used to change arp parameters, so I would to control it from different device (another controller). ARP config is assigned to port, where notes comes on. Even on arturia keystep pro there are no good controllers to assign arp config, so it makes sense to allow control by different device. Now - arp function is usable only if it's predefined in MRCC config. In jam it's necessary to do quick changes and one controller (for example MIDI Fighter Twister) is perfect to control all of them. I'll would request this feature, buf please let me know if it's possible to do that somehow (virtual cable?).

In summary:
USB Port 1 CH1 - controller - only for notes, to set bassline or accord. Assigned to ARP#1
USB Port 2 CH16 - controller to change ARP parameters in ARP#1

Above example is for USB, but i would be able to use DIN-5 too.
