[sdiy] Seeking for help, building a bass synthesizer.

[Rouslan Placella]

Hi everybody,
my name is Rouslan.
I'm trying to build a bass synth. And I found out that to generate a suitable

wave for this I need 3 VCO. The first one should do a regular sin wave, but
the other two should do something like the figure B(at twice the frequency).

I still didn't come up with anything...
Can anybody help me out?



  _     _     _
 / \   / \   / \         (let's say this is a sin wave)
A.  \_/   \_/   \_/


  _           _
 / \___   ___/ \___   
B.     \_/         \_/

Thanks to everyone in advance, Rouslan.
