recevive from pc but not send to pc with faders

[icl7805]

hello
im trying to use the b2.961rc1 with a bcf2000
i have configured midi in and out.
i have tested with the pantilt window.
when i move the pan tilt inside the freestyler, the bcf2000 faders are moving correctly.
but when im moving the bcf2000 faders, there is no reaction inside freestyler.
then, i have tried to assign a fader to a dimmer wheel.
i have the same problem and its worse because when im moving the dimmer inside freestyler, the bcf2000 fader only goes to 0 all the time.
buttons like black out or freeze are reacting from the bcf2000 to freestyler.
i have tried with bcf2000 in u2 and u3 config connected directly with usb cable

have you tried u1? u2 u3 are used for the midi outputs.
have you got a fixture selected when you move the faders.
is there any other options you nhave changed?
