mapping out and dysfunction with modifiers

Hello everyone , sorry for the translation with google , start by doing a critique on the mapping file and led away on little documentation .
I Got a problem with various versions of Cross - DJ and I can not find solved :
1 ) when an active modifiers ( holder or toggler ) LEDs on the MIDI device is locked , if you enable + a modifier you go into confusion .
2 ) I am trying to map a DJ-tech mixer-one and I can not operate the LEDs of the VU- meter ( I lost a lot of time reading around and try )
3 ) always as an example , the mixer-one , if an active modifier on channel A and then step C , the buttons do not work neither led nor , I must return to deactivate the modifier A return to C and then it works .
I would like to know if there are solutions to the above, thanks .
