iirc, bang~ uses pd's timer callbacks, which are only executed once every 
dsp tick, i.e. each 64 samples.
while pd has a notion of `logical time', timers for the interval of 64 
samples are executed at the same time. if the same timer callback is 
scheduled twice during this interval, it is only executed once ...

Nothing exists until or unless it is observed. An artist is making
something exist by observing it. And his hope for other people is that
they will also make it exist by observing it. I call it 'creative
observation.' Creative viewing.
