I was thinking the same. Though Karplus-Strong generally starts out with a triangle, pulse or white noise, if I am not mistaken?

  The vanilla algorithm starts with buffer full of white noise. However it originated as modification to a wavetable synthesizer that modified the waveform samples as it played them: http://www.youtube.com/watch?v=dUcNzPhZdwk&t=28m34s http://www.youtube.com/watch?v=dUcNzPhZdwk&t=28m34s

    Nice video. Need to learn more DSP.

      Depending on what your current background is (need to know a bit of math, very basic complex numbers, etc), when I started out to learn DSP, this tutorial helped me loads: Yehar's DSP Tutorial for the Braindead http://yehar.com/blog/?p=121 http://yehar.com/blog/?p=121 It was an ASCII textfile when I read it, back in 1999, doing demoscene stuff, someone had coded a speech synthesizer in a 4k demo. So I had to email that guy to ask them "WAT??" and he answered explaining me basics like how to set up the Soundblaster with a streaming circular buffer, then sent me to read this tutorial, and explained loads of other stuff. I also dug a lot of interesting things from the music-dsp mailinglist and many articles on Harmony-Central.com. That site still exists, but I can't find any of the old articles and tutorials related to digital synthesis any more. That's where I first read about Karplus-Strong physical modelling of stringed instruments. I think they were in a section called "Music & Computers" or something, but nowadays that place seems like a weird sort of blog/forum combo. I always had the feeling that the DSP section of Harmony-Central was only a small part of the site's intended purpose, does anyone have an idea where those articles went? (come to think of it, I don't think I've simply tried old versions on archive.org yet)
