Study the Buchla triangle-core oscillators of choice.

The lack of square wave can be remedied by setting up a differentiating 
circuit (integrator with R and C interchanged) and then put a comparator 
(against 0V) on that output to form a proper square. Then just continue 
as the general plan, i.e. a CMOS-switch controlled by the square to 
provide +1/-2 switched gain. Not too complex.

Have fun.
