Can’t chain targeting

Hi there,
first time using CCS; but newbie problems…

I want to fast select a device inside a rack. But not sure if I’m configuring everything in the right way.

My goal:

– Have an audio effect rack inside a track with n repeated effects inside chained.
– Having the ability to select one of the n fx fast (with pressing the related pad to that device)
– Having the ability to manipulate the 10 parameters of that selected effect (with 10 knobs mapped to the selected device).

I guess that the way to do that with CSS is:
1: Create a select devide:
Script Name > Model 1 > Track 1 (if I want to control track one’s devices) [type track; number 1; other no; led no] > Device 1 [ Device 1; Chain 1: number 1; in order to select the first device chained) AND > Device 2 [Device 1; Chain 2; Number 2; in order to select the second device inside the rack]
BUT this doesn’t work for me. Always selects the first device of the chain, even I played with every mathematical combination of numbers in Device, Chain and number, going wild crazy, but anything changes.

2: Adding a new device after the last n device; with parameter Bank. But, until I didn’t have succes in the first step I’m not considering the second.

What I’m doing wrong?; it seems to me that targeting which device I want to select is one of the main features of CSS and It should be an easy to configure thing; but I’m not lucky….

Maybe there is a very stupid solution ahead, but I can’t find it from my own.

Thanks in advance to anyone who will try to help me.
