[PD] realtime chopping of a sound file

[PF]

hi
i want to play a long sound file and while it is playing, be able to
cut it in several parts that i later can load/play on tables.
the way i would do it is to arbitrarily record stuff onto tables
whenever i want to "cut" one of these sections. but i need an
effective, smart and modular approach to the many tables situation (ie
i dont know how many of these cuts i wanna make, so i should be able
to create tables on the fly), i reckon using variables in the tables
names. i bet there is a good example somewhere, but i could not find
it.
help?
