You could check out s_looptable in the rc-patches which wraps [loop~] and [tabread4~] https://github.com/danomatika/rc-patches/tree/master/rc

I am trying to play back a table in varispeed and am getting artefacts. I looked into vanilla's 'onset* message for tabread4~ but since I want to play tables backwards as well a solution with an audio signal as offset message seems simpler to me. Now iem_dp (double precision) has tabread4~~ which features exactly that. The only thing that is missing is me understanding how to build a wrapper around tabread4~~ so that in can be a drop-in replacement abstraction for tabread4~. How can I derive the offset signal in the first hand place? For messages I would devide the index by a certain numer, for example 100000, truncate the result and use this as the offset. Then I would use [modulo 100000] to get the left input for tabread4~~. Am I correct to go this way?

How would I truncate an audio signal in Pd?

How would I calculate the modulo of an audio signal in Pd?

Is there a more elegant way to do this?

Thank you for all ideas! best, Peter
