Hi all,<br><br>In the attached patch, Iīd like to have a vibrato that is the same (in pitch) both above and below the carrier frequency.<br>I donīt know how to do it in pd.<br>So far I found a solution at the csound mailing list.
<br>in csound a solution is to use&nbsp; &quot;cent&quot; that calculates a factor to raise/lower a frequency by a given amount of cents.<br><br>---- csound example -----<br>kvib&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; oscil&nbsp;&nbsp;&nbsp;&nbsp; 1200, 1, 1<br>&nbsp; a1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; oscili&nbsp;&nbsp;&nbsp; 30000, 440 * cent(kvib), 1 
<br>----- end csound example ----<br>here is the link from the csound mailing list.<br><br><a href="http://www.nabble.com/Simple-vibrato-question-%28was%3A-Not-a-Number-ierror-in-pow-operator%29-tf21490.html#a58740">http://www.nabble.com/Simple-vibrato-question-%28was%3A-Not-a-Number-ierror-in-pow-operator%29-tf21490.html#a58740
