MIDI with QL1 / conflicts with 2 commands

How can I use faderstarts and ON/OFF on the mixer and remote control the players?
I want to either faderstart the player or start it by using the ON button.
I want that when the ON/OFF is OFF, the player is muted, and the fader volume is inactive and set to “00”.
Is it possible to use both commands that are acting on “same” parameters?

Any hints?

Thank you!
