aaaccch yeah - just been messing about with dfm1 on sc, and, yeah, all you get 
is a sine wave when it's just beyond self-osc, so, the filter's character is 
only apparent at something beyond that.

monotron filter - in case anyone was wondering ;)

maybe a bit better than (first version) MS20, primarily cos the PCB and 
components haven't been subjected to temperature cycling and humidity.... :)
