Hello Ingo,

If you simply combine the original saw and a suboctave square, you get a wave 
that's not really saw-shaped, isn't that correct?  Isn't it more like a 
sawtooth superimposed on a square?  Or am I not clear on the method you're using?  
I would love to be able to get a very pure sawtooth suboctave by some simple 
method.

Best regards,
