To encourage: this connection should be simple.
Use a Midi Monitor programme to connect up with the BCR2000 and see incoming Midi as buttons are pressed etc.
This will give you confidence in the Midi device name/port name and the BCR2000.
Also tell on the forum which OS you are working on and what drivers you have intalled and then others who have that OS can also help with confidence.
If using OSX this may help:
https://feelyoursound.com/setup-midi-os-x/ since it is the port name that should be matched not the device name.
If still not working, include a screen print of how the OS lists the ports / devices?
