[sdiy] Karplus-Strong overblowing?

[Tom Wiltshire]

It's worth pointing out that a delay line that resonates at f also resonates at 2f, 3f, 4f, etc. So the filter is very important because it's the only thing that acts as any kind of selection between those different possibilities.

So, if you want a weak fundamental with stronger partials, then you might adjust the wideband noise burst at the input to have a weak fundamental. You could also tune the filter to favor specific upper partials. There really aren't many knobs to tweak in K-S because there are so few elements.
