[sdiy] DCO Question

[Mike HEQX]

Very interesting. Looking at this from the perspective of a TOG synth. 
You can determine which harmonics you will allow in your series by the 
divisions you choose and relative amplitudes that you set. So you can 
artificially allow harmonics that may be suppressed to now be heard / 
felt. If there is truth to the psycho- acoustic phenomenon, then is it a 
good idea to have supersonic and sub-sonic harmonics in your signal?
