Does anyone know of Pd implemenation (or external) of a non- transposing variable delay?

what about vd~ ?? Is it not what you are looking for ? Or is "non-transposing-delay" any kind of special term i dont know of ??
I guess what Jamie meant is that during delay-time ramps, the signal in the buffer is being played at a speed!=1 which produces a temporary pitch shift.
If what you want is to change the delay time every once in a while, I once implemented it by using 2 delay lines and switching among them: while delay line A is being used, you change the delay time of delay line B and then, once the critical zone is passed away, cross-fade to delay line B and leave delay line A idle.... and then viceversa again and again ..... something like that. I also used feedback.
If you need to _continuously_ change the delay time without shifting pitch, I guess you need to apply the same techniques that are used for "non-transposing" time-stretching....
