Eml synthesizers

I posted here a little while ago about this, but I have since figured out more of what it's doing 
wrong.

Long story short is that the Saw, Negative Saw and Square wave do not work as they should. 
The triangle and pulse work fine. The three waveforms do not  work in either LFO mode or in 
audio mode.

Now the really strange thing is if I have OSC 1 controlling OSC 2 as an LFO what happens is if 
I have lets say SAW selected and I switch it from high to LFO mode is will ramp up once and 
just give me a high pitched sound once ramped up. Basically, it doesn't start a cycle again. 
Same with NEG SAW. If I switch if from high to LFO it just ramps down to really low tone but 
does not repeat it's cycle. Any idea what the culprit could be? My initial guess is a capacitor.

I can tell from the schematics that there is a section where the saws and square seem to be 
off on their own which would explain why the three don't work, but the other two do.
