[sdiy] Karplus-Strong overblowing?

[Mike Bryant]

You should be able change the response of the filter in the feedback loop by using more taps into the delay line with some gain to perform this.  However the filter would stay peaking on one frequency so you'd need to have a separate K-S element for each note of the instrument.

Note you'll also be nearer the point of instability so have to use it carefully.

Subject: [sdiy] Karplus-Strong overblowing?

Does Karplus-Strong synthesis allow for overblowing? Are there any
modifications to it that allow it?

Overblowing is when you blow into a reed instrument too hard and
essentially the fundamental becomes much weaker and the higher
partials become much stronger, kind of "overdriven".

Thanks
