I have experienced this too.  One time I was working at 48000 (Audigy + ASIO on my desktop) and then I broke my foot, after which I used my laptop exclusively, which has no preference for 48000.  I attempted to just change everything to 44100, and it sounded distinctly different.  I don't recall what I ended up doing, and my work files for that piece were one of the casualties of the Great Linux Csound Installing Hard Drive Massacre of 2007.  I salvaged the finished mp3, but the work files are gone.

<br>I don&#39;t understand why changing control rate and sampling rate I&#39;ve<br>differences in timbre and amplitude values.<br>I&#39;m working with an instrument that has white noise filtered by a bank of<br>resonant filters and a waveguide reverb with a lot of delay lines (with
<br>delay opcode because I don&#39;t need to change the delay at kr).<br>Using kr 441 sr 44100 I obtain a sound I like (this is the strangest<br>thing!), but with kr equal to sr (44100/44100), I have some resonance peaks,
<br>a slightly different timbre, and greater amplitude values...I don&#39;t<br>understand why! I DON&#39;T use modulating delay lines! And I don&#39;t use any<br>krate variables! Why changing kr influences timbre and amplitude? Same thing
<br>if i try with sr 96000, timbre changes (and it&#39;s natural because there are<br>more high frequencies and a cleaner timbre), but amplitudes are about TWICE<br>great!<br>Thanks for your help and sorry for this newbie question.
