Reply to APC40 CC to MIDI notes?

Hey folks,

After 2 days of research, I'm now just about ready to give up. What I'm trying to do really doesn't seem complex, although I can't seem to find a definite answer on how to do it, or even where I should start. All I'm trying to do is this:

On my APC40, where the 8 Activator buttons are, I want them to send 8 different midi notes, ie, C0, C#0 D0, D#0 and so on, but only just 8 of them. Optional bonus extra would be that shift+those 8 would do 8 different ones, but that's an optional bonus extra.

That's all the customisation I need. No VU Meters or any of that kind of stuff, just that.

I know it can be done with things like Bome's, or M4L, but I'd like to do this without having to fork out more money. I did find an LUA script that I could work with, but I don't know if/how to use it with ableton.

HELP PLEASE!!!

Cheers,
T
