Midi learn: distinguish channels

[decrecementofeliz]

Hi, I'd like to map the same midi CC number but on different midi channel to different parameters in Helm.

CC 64 Channel 1 > assign it to one parameter (i.e. filter-cutoff)
CC 64 Channel 2 > assign it to another parameter (i.e. filter-depth)

In qtractor, the plugin properties window do learn and specify the channel of the assigned midi CC, but Helm still responds on both parameters at the same time when receiving any of the CC messages. Is this something related to Helm only or maybe it could be solved with any other plugin in the DAW (midi filters, etc.), or messing around with ports and connections in jack-midithrouhg-a2j??

I've tried different things but no luck. Any help? Thanks!
