Rack with in a Rack within a Rack selection – Custom Code

I have an issue, I am trying to get CSS to select the 3rd Rack within Device 1. (see Ableton Screen Shot)

I know you can so this with the Device Parameter mapping – you are able to add multiple chains to a device (see screen shot 1) but when it comes to the ‘Song>Device Select Mapping you can only choose one chain. (screen shot 2a+b)

I would like the script to function how it does for the device parameter setting. With the first chain set to m1 and the second chain set by m2.

I have inspected the code as best I can and have tried adding a second chain selector via custom code for it but I got syntax error:

self.song().view.select_device(self.song().tracks[0].devices[0].chains[self.get_modifier_value(“m1”)].devices[0]).chains[self.get_modifier_value(“m2”)].devices[0])

Do you think there is some sort of custom code available for this type of mapping?

The script is attached 🙂
