this leads me to question, that is coming up to my mind again and again, but i still didn't come to a satisfying conclusion. there is another method of getting clickfree loops, that hasn't been discussed yet: detect zerocrosses and loop only from zero-cross to a zero-cross. but how are such things implemented in pd? the only way i can imagine to detect zero-crosses is to convert each audio-block to list of floats using [pack~] from zexy. this approach actually means, doing all the detection stuff in the 'message-domain', which is very cpu-consuming. how does one overcome this problem? this problem arises always, when an event (message) should be triggered on certain conditions in an audio-stream. i know a lot of such cases and it's always difficult, when not impossible to do it in pd. it can be quite frustrating to know the solution for certain problem, but at the same time being unable to implement it. i have the feeling, that these kinds of tasks are often delegated to externals, which is a pitty, since pd is an AUDIO-programming language.
There is an external that detects zero-crossings. ;)
Now seriously: I think, one building block that is missing is Pd is the opposite of [vline~], that is and object that could schedule a message with sample-accuracy according to incoming samples, and not only with the accuracy of a block.
