Looping over a group of tracks

Hi,

How can i loop over a group of tracks?

I have identified the group id and it has been stored into the m1 modifier.

Now i’m trying to loop over the tracks in this group:

self.song().tracks[self.get_modifier_value("m1")].tracks

This does not seem to work.

What is the proper way to do this?

Thanks!
