Today I did some tests with feedback delay lines and found that they do in fact behave very nicely. The handbook says that for audio feedback lines a send~ -> receive~ or a throw~ -> catch construction can be used. Seems like there is a third (and even a fourth) option: a delwrite~ -> delread~ or a delwrite~ -> vd~ will do the job as well. I was very pleased to find that the delay line even provides an inbuilt compensation for the block size delay. The only difference to a regular non circular delay line is that the minimum delay time is equal to the blocksize because the delread~ is executed before the delwrite~. Question: I did not find any mention of this use of delay lines. Is it safe to use delay lines this way? Or is there a chance that this feature will be removed in a future version of pd.?

best regards
