Reply to light settings for launchpad (help please)

Hi,

I'm making a mapping for my launchpad and the lights are driving me mad!!!

I have seven buttons all set up for 'loop set + size' each with a different loop size, the lights are set up so that they are green and then turn red when loop is active, the problem is if any of the loop buttons are activated all the lights turn red.

What I'd like to happen is, when a loop is turned on for 1/4 loop only that button turns red (so it would be easier to know which loop button is on).

Can this be done??? if so how please??

Thanks M.P
