[sdiy] Tri-core oscillator sync

[Tim Ressel]

Hi,

I have made a triangle core oscillator that works really well except for 
the sync. I implemented what I thought would be hard and soft sync but 
the results were disappointing. As I understand it my "hard sync" is 
known as "reversing sync" i.e. a rising edge causes the steering flip 
flop to change state and thus the wave reverses. My "soft sync" changes 
the upper set point on the window comparator.

I would like the soft sync to sound like the Doepfer A-110-2 oscillator 
soft sync if possible.  Thoughts?
