Depending what you want to do with the LFO.... a very slowly stepped LFO 
is very noticeable indeed. This is just about the only thing I wouldn't
want to do with a micro, but I'd like to hear more opinions.
The 3080 is good, but the range is (in practice) only about 1000 to 1.
(was there a work-around for that? Transistor as timing resistor?)
