Impossible to control faders with Akai midimix

[fedjai]

Hi there !
I just purchased a DVC fun, registered it, installed daslight 4. I would like to control faders in a Scene in the Univers panel.
Akai midimix is perfectly recognised in midi preferences and I would activate control for a scene with midimix button.
I can also control Dimmer general in live view with fader from midimix.
Issue comes when I want to operate faders when editing a scene in the Universe panel, I right click on the daslight fader, click edit MIDI mapping, move a midimix fader - daslight recognise the number/channel and I could see numbers increasing/decreasing - but in the end fader is not operated.
Can someone help ?

Hello,

Only channel faders that are attached to a fixture can work with MIDI.
Have you patched a fixture before trying to control your faders ?

Best regards,
