however, it is not that easy: no loops in my patches (I wouldn't have been able to substitute them by patch cords would I), but nonetheless delays between r~s.
patch cords and audio busses (send~, catch~) are working completely different ... patch cords are compiled into the dsp graph, audio busses aren't ... you can rely on patch cords, you can't rely on busses...
i'd prefer to have the as part of the dsp graph, too and only resulting block delays if necessary (feedback), but this would require some non-trivial changes to pd's dsp core ... this would especially be tricky, if dsp chains would be changed from one monolithic dsp chain to segmented dsp chains...
cheers .... tim
