Same Midi Ccs From Two Midi Controllers

I have two midi controllers sending the same MIDI CCs (CC7…) so if I map one of them to control for example a filter cutoff, when I tweak the other controller’s knob which sends the same CC, the filter cutoff value changes unexpectedly…I would like to “discriminate” between the two controllers, it is possible?
Thank you!

Ok, I solved the problem. One of the controllers is a Doepfer Pocket Electronics, so I changed the CCs from 7 (the classic midi volume) to other values thanks to the doepfer software editor!

Changing MIDI Channel may be a more suitable solution.
