Yamaha EX5 FDSP demo, turning noise into a string sound

video by Floyd Steinberg

"Just a quick improvisation. This patch is made from noise and a piano sample (in part 2). You can download my EX5 patch set for free, no registration needed, from This patch is I1-041 (C09). If you want to know how to create this sound, I already did a video on that: [posted here]
Put the FDSP 'Water' effect on a burst of noise. Tweaking the parameters a bit turns the white noise into a guitar string sound, this is called karplus-strong synthesis. As FDSP can manipulate individual notes, this results in a polyphonic karplus strong track. I set the encoders up to control the decay time of the string sound and the volume of the piano sample, and the mod wheel controls the loudness of the FDSP effect."
