Cool patch, Frank. Note though that by converting the click signal
from samm~ into a bang, you are rounding it to the nearest vector. As
I showed in my demo at LAC, I can make metro perform poorly in a
subpatch with a very large blocksize (say 4096), but samm~ will
perform the same irrespective of blocksize.

It is true that samm~ and friends were originally written for MaxMSP
to deal with its problematic event-level timing. OTOH as my paper
points out, Pd's audio thread is more susceptible to interruption from
GUI events than MaxMSP. In addition to convenience, The benefits of
samm~ come from its integration into a system of signal-level
triggering, particularly with the soundfile player called player~
which I think has some nice features.

Best,

Eric
