object~ is so common that Pd has it's own naming mechanism built-in.
it is not generic at all, that is why there is a need for the hexloader.

probably, because you have not been able to load the object?
i think it makes an object quite unusable if you either have to upgrade
to the newest bleeding-edge version of Pd or use another external to use it.
i personally prefer to be able to work with any version of Pd (working
on several machines i don't want to spend my time keeping all of them in
synch; i haven't found the time to automate the synching (via etherboot
or whatever)), and with almost no externals.
zexy i know well and use it so much, that i don't care for having a
number of externals available all at once; but loading
(+installing+compiling) yet another external just to be able to use the
one i can already use anyhow, seems to me like an overhead.

what i meant to say is, that i put some effort into being able to
compile zexy as single externals (after all i have added this option to
the configure and have written the hexloader...), but the way i use it
in everyday life is as a single library.
that is why this has the official support.

i am not sure i understand that.

yes there is a point.
i think ypatios has posted an example patch on how to use it.
what you can do with [tabread4~~] out of the box is have one signal act
as an offset (large numbers), and the other one as the relative movement
to this offset (small numbers), e.g. for a granular engine that works on
big soundfiles (which was the trigger to write this object).
what you cannot do is to have one very long ramp (e.g. a [line~] going
from 0 to 1e10 in 50e13 ms) that smoothly reads the array with
[tabread4~~] without a special object like [line~~].
however, thomas (iem) has now implemented a number of objects for
"double-precision signals", including [vline~~] (though it is not fully
working yet)
i don't know yet, when we will release this library.
