I think the best solution for me is to use 4 [zl.compare] with [expr].
But it's all not so good... None of the algorythms is working with my setup, because of some bug, or i don't know.
[zl.compare] somehow is not comparing complex lists even if they are equal.
But with simple lists everything is ok.
Here is example.
@ivnos it should work both in 32 or 64 bits. At least that's what I'm seeing here using the latest versions of Max, Live and zsa.descriptors. Feel free to contact me if you're still experiencing some problems.
