A-800 Pro: anyone know if it can be configured for use with Music Creator 6 - and how?

I recently bought a Roland A-800 Pro, and am generally pleased with it apart from 

(a) the really resistant aftertouch, which I note has been mentioned elsewhere in this forum (my old Roland JX-8P also needed to be almost stood on to respond to aftertouch - eventually, aftertouch stopped working altogether) and 

(b) the horribly baffling and vague instructions on configuring the A-Pro's controller maps.
I have seen that there's one post dealing with setting up the A-Pro with Sonar but I'm not using Sonar and uncertain how far it applies to my situation.

I'm using Cakewalk Music Creator 6, mainly because I wanted something that was really simple to work with. In the past I have struggled too much with software, Sonar included, and just felt I wanted to be able to write and record music without needing to study for a degree in understanding how to run the software. I'm the wrong side of 60 years old now, and don't find technology anywhere near as easy to understand as I used to!

I am assuming there's every likelihood the A-Pro will work with Music Creator 6, since it is basically from the same Cakewalk 'stable'.

Principally, I'd be very happy even if I was only able to get Music Creator's transport controls to respond to the L1 - L8 buttons on the A-Pro, but I presume once I can grasp how to do that, I will probably be OK to assign the other controls too.

So - are there any kind souls out there who can walk me through the set-up procedure for the control maps? 

I am confused by the A-Pro Editor's interface, which seems to really limit the options of what can be assigned to which control (unless you know exactly what hexadecimal codes to enter, maybe) and further confused by a similar but seemingly functional 'mock-up' of the controller that also appears onscreen with functions attached to the various controls that somehow seem as though they were chosen from some different lists! Is the functional software representation of the A-Pro intended for testing all the functions work as expected before transmitting the data to the A-Pro itself?

Likewise, I am confused by the plethora of ACT buttons on the hardware and both software representations (and on my Standalone / VST soft synths as well). If I need to activate ACT, do I activate just the hardware one, or the software ones, or both, or what? 

Any help will be gratefully received!

Cheers!

Many thanks, Jlien,

Step 3 helped. I'd already got A-Pro in there as a control surface but had not realised that I needed to select the In and Out options from drop-downs.

The ACT button didn't light up, but the transport controls on the A-800 Pro now start, stop and pause playback and initiate recording. That makes me very happy. The L1-L9 sliders appear to be doing what they should for volume of individual tracks, too. I've not tried anything else yet, but will become somewhat more adventurous now I can see they two items are talking to each other with more than just notes!

Thanks again!
