Midi cc with different midi chanel

Hey guys
I use ableton live to control my ambika ( note and midi cc)
To control my ambika i use a multi mapper cc on max for live But when i change a value on live it change the value on all part on the ambika, all my part are on different midi chanel. How can i change a midi cc just on one midi chanel
Thanks

Did you take a look at what max for live sends out? Take a midi monitor and verify that your mapping is correct.
