PLAN B analog blog

My mind tends to wonder during the drudgery of soldering Plan 
Bs and I got to thinking about a thing called a wavemaker, which 
would take an external AC signal and shape it into a sine, tri, 
saw , square and morph with separate outputs for each.  

Not sure how many would agree with me that I think this is a 
useful thing - but for instance, it would be the perfact companion 
to a freq divider when used as a sub ovtave generator because 
you wouldn't have to settle with the square wave output if you 
didn't care to.

It's going to be a bit of a task to set it up so that the input signal is 
'just right ' for the waveshapers to fire up, but with the help of a 
window comparator, attenuation knob and LED at the input stage 
it would sail.

Any thioughts on this?
