don't ask me, ask miller (imho, this is one of the big design faults of pd). i can only guess, that it is done due to performance reasons ... it saves one pointer dereferencing. this is of course not a real explanation, as it is perfectly possible to keep track of the pointers in the dsp chain ... neither is it that expensive to do an additional pointer dereferencing ... > It seems it does not even recompute it when you send a > [set ...( message to > a tabread~ (at least I get no dropouts)... why do it when you resize > a > table? that is the other direction ... when objects are bound to the table, then they can just call garray_getfloatarray ... if tables change, garray_getfloatarray has to be called from all objects, that are bound to this table ... cheers, tim -- [EMAIL PROTECTED] ICQ: 96771783 http://tim.klingt.org I had nothing to offer anybody except my own confusion Jack Kerouac
