MixTrack Pro 4Deck Mapping Help!

Okay so I am a mixtrack pro user and recently start to use 4 deck contro.. but I've been doin it by hand with the keyboard and mouse.. when I would much rather be using only my controller! So I need help with using modifiers.. they are completely losing me at this point.. all I want to do is set the key button on each deck.. (left to c and right to d)...but when there leds are off I want to be controlling a and b...and I would have the same functions mapped for each deck. But how do I make sure that if the left led is on it will use the controls to only function with deck c? Etc etc. If anyone could please help me out that would be great. If you have a mapping that works exactly like this and you could just help me map it to the way I like it to function thatwould be greatly appreciated ..as well as any othe help or advice.... you can comment on the thread..PM me or email me at [email protected]
Thank you so much!
