I am working on a new drone project and need to create a mixer with 12 feed through outputs, so I created a vol.main.mix and a vol.aux.mix file with 6 outputs each. I also changed the rcS and interface code to call them up, but doing this I have received some error messages, but not sure why.

The error that bugs me the most is the one about the update rate, because I checked and the variable PWM_RATE is 400, but it still gives out this error. A reason for this to happen might be that I commented out the SYS_AUTOSTART feature, because it always set the variables with wrong information.
I also thought about using the IO_pass mixer, since that one is already a passthrough mixer, but I am not sure how to access 12 different outputs. I need 6 outputs for motors and 6 for servos.
I would be happy if anybody might now a elegant why to do this. I think my approach creating all new mixers might be to complicated for the easy mixer I need.
