I can see 2 probable causes for that: a change in frequency means a change in
the delay size and if the code does not take account fractional delay
interpolation it changes at integer sample positions. I also would suggest you
to try kr = sr. ksmps >1 can cause very annoying transients when dealing with
delay lines.
