I’ve had those two only a couple of weeks (which translates to just a few sessions of patching) but I’m pleased with them. Although m0 is straightforward enough in terms of function, it’s easy when zoomed out to e.g. make the envelope disappear and remain hidden for some time (still the zoom ranges are part of what makes Mungoes so interesting). I like that you can assign the envelope internally to either of the first two inputs, and if it goes to the first one you can send a second envelope (or whatever signal) into it as well, attenuverted as desired. Could envelope and ring modulate a signal at once, for instance. At the same time the envelope has its own output to go wherever else. I bought m0 mainly with d0 in mind, and they do work well together.
I think f0 is a super filter! I had no idea what I was in for and just hoped that because it was Mungo it would offer something cool, and it does. It’s initially very clean and seems partly intended for controlling distortion with FM, but there are lots of possibilities. Like m0 it patches internally, on one setting allowing two (separately attenuverted) signals to control cutoff. Aside from ordinary filter functions, I’ve got some gorgeous bitcrush-like sounds out of it that I liked a lot.
