[sdiy] My first schematic, me too

Usually the glitch is from the triangle that feeds the sine shaper.
Its usually generated from the sawtooth, which causes a discontinuity
where the reset occurs. Best way around it is to use a triangle wave core...
which usually has its own problems to solve... 

I did a little study on how to eliminate the glitch from the triangle... 
I'd predict
the reset time (perhaps with a comparator that is set just below the normal
reset point, then use a track-hold circuit to ride out the glitch.  Woah 
its pretty
complex but looks workable. Don't know if the distortion would be worse than
a small cap to cover the glitch... at least this method would keep the 
effects of the
glitch reasonable constant with frequency
