Problem with the midi output on my bcr2000

Problem with the midi output on my bcr2000

Hi bros!
Im trying to map this on my bcr, one knob is the filter and when I push the knob y goes back to the middle value. I want to send an out message to the bcr2000 so when I push the knob I will see the knob in the middle value on the bcr2000 too.

The problem is when I try to configure the outs and I move the knob its constantly going back to the value it had before I moved the knob.

How can I configure it well?

Thanks
