[sdiy] Weird data patch question

[Tim Ressel]

Yo,

True, this is a very small effect. But keep in mind
that the ear is most sensitive to frequency. I've
always been fascinated by why synths sound so, well
not different, but separate, than their natural
counterparts. I suspect this is one of those subtle
effects that contributes.
