Hey folks!

I continue doing some reverse engineering of virtual analog synths.
Here is the the picture of how the whole range of sawtooth waves is produced
for some generator.
The upper signal is the basis prototype (C-1 or ~8 Hz). The bottom is some
higher freq.
The 0 point remains at the same position, the left and the right parts are
shortened, not equally (!). 
Also some amplification takes place. 

Does anybody know something about such technique?
Any suggestions on best implementation? 

My thought is to obtain the best fitting function, code it using appropriate
GEN table, 
then adjust phasor range using limiter.
