Reply to akai apc40 - controlling the led's

help.
can someone please explain to me(in detail)
how u can midi map ur lights to turn whatever color u want them, i got the apc40 so i can control cue points, loop rolls, and more in scratch.

i wanna be able to have 10 buttons turned to the color green and stay on untill i hit the buttons, as soon as i do.. they flash, indicating that they are turned on, and in use.(loop roll)

and then i wanna another row to be playing cue points and another row for setting cue points, of course these would be a different color as well..
possibly orange and then turn red when hit?. not sure yet

i heard that maybe Bome might be the way for this, considering that that scratch cant send a midi signal back?

please... anyone ?

thnx in advance
