i had a look at my test-patch again and: there definetely _is_ a drift
over time. i am very confused, cause i tested it several times and i was
really sure, that behaviour of [tabwrite~] must have changed. i even
tested with older versions of pd to make sure, that behaviour was
different before. anyway, when i tested again with my actual pd, i
noticed a drift over time again. i can't recall exactly, where i got
that pd-version from (from miller's site or from cvs), that didn't show
any timedrift, but it is very likely, that i recompiled pd in the
am i a victim of a strange fata morgana kind of thing, or is there
effectively a version of pd around with different [tabwrite~]-behaviour?
