You can do a lot with Maths. You can do a lot with other DUSG-inspired modules as well. Some of the things you can do with modules are "Yes, that's clever, but it ties the whole module up and doesn't let me use it for more fundamental things".
Pam's is not a sequencer, as far as I'm concerned. It provides clock division and multiplication, synchronized LFOs of various shapes, Euclidean rhythms, some basic logic, clocked random CV that can be quantized (so random notes in a musical scale, but not a fixed sequence unless you dive in and use the LOOP function to repeat a random chunk – you can't write your own), and smooth random CV. It is not the most tweakable in the moment, but the menus are not too deep, and for set-and-forget it is terrific.
