The handling of all incoming MIDI events is equal, but it sounds like your keyboard (or controller) sends CC over a different channel, is this correct? In this case you have to change the channel setup on your keyboard/controller
How do you mean this? i thought i send it independent through 176.
“176” is 0xB0, that´s Midi channel 1. So if your note information is on another channel, your answer to TKs question will be “yes”
So if you change the channel of the notes to e.g. ch 5 and only route or filter stuff on ch 5, of course the CCs don´t get through because they are still on ch 1. If you want to send CCs on other channels: use (175 + channel number).
