Hi John,
 
	Thank you very much for your repply, 
	In mean time I found out what was going on that nothing worked. The related hvar file was missing on Community folder.
 
	I will remove the specific profile as you suggested. 
	The way I fist programed (following the example os this post above)  the knobs didn't work well. The increments were not stable. I foud it more effective to program only  "U" (pulse on release) to get one by one incremets. 
	4=UB,4,CPFNX320_FCU_ALTITUDE_KNOB_DEC,0     -{Preset Control}- 
	6=UB,5,CPFNX320_FCU_ALTITUDE_KNOB_INC,1     -{Preset Control}-
 
	Is that really the best way to get stable 1 by 1 increments or you have a suggestion to improve this?
 
	Again, thanks for your support and congratulations for your very good sofwate tool.
