Drum Rack question

Hi. I spent a bit of time reading the old posts regarding drum racks, but I can't seem to get an answer that works for me (yet). Judging by what I have been reading, it looks like maybe drum racks aren't 'a thing' here (yet), but I don't know if things have changed with CSS.

Anyway, I assume that a drum rack is like any other rack, comprised of chains (as an example, for a simple 4x4 drum rack, there would be a total of sixteen chains) with each chain corresponding to a different 'pad'. For my 4x4 drum rack, I have sounds that all each have utilized all eight of their own macros to manipulate various aspect of that particular 'pad' (frequency, reso, etc.) - that is to say, each of the sixteen pads has it's unique eight macros that control that sound only, and I want access to each of those! Also, the drum rack itself has 8 macros.

What I am attempting to do is use my sixteen MFT buttons to select the corresponding "chain" from the drum rack, and I assumed that the chain numbering would be 1-16 (I think I am wrong on that assumption). My Drum Rack is on Track 1, and I am using the Chain Targeting command that I have set to Device 1(the drum rack) and for each button, I am incrementing the value of the chain (device 1; Chan 1 for C2; Device 1; Chain 2 for C#2, etc.). Now for each button of the MFT, I am using the Select Device command using the above Chain Targeting strategy - for example the bottom left most button is set to Select Device for the Device 1, Chain 1 all the way up to the top right button being Select Device command for Device 1, Chain 16. I am attempting this approach because I don't want to trigger a sound when pressing the button, I only want to 'open' to that sound with it's delicious corresponding macros. I haven't gotten there yet, but I also want to be able to use the bottom 8 encoders of the MFT to manipulate the 8 macros for that pad I am trying to select, and the top eight encoders to control the eight drum rack macros. I will want to work on figuring this out for myself, so try not to spoil that part for me! With respect to the buttons, of course, it hasn't really worked, but it kind of has. Two of the buttons worked: the bottom left button (1st pad or C2) and the forth row left-most 'pad' (13th pad or C3) both trigger a change, but none of the other buttons do. Interestingly, the 13th button activates the 5th pad and not the 13th pad, like I would assume. It leads me to believe that I am more or less on the right track, but that the numbering assignments for the chains is not right. Does anyone have any insight into this?

Thank you,

Greg
