its right input decreases in value (as a phasor~ does each period \,
for example.) Both inputs are audio signals.;

#X text 14 82 The "set" message sets the output value (which continues
to be updated as normal afterward.) The "reset" message causes samphold~
to act as if the specified value were the most recent value of the
control input. Use this \, for example \, if you reset the incoming
phasor but don't want the jump reflected in the output. Plain "reset"
is equivalent to "reset infinity" which forces the next input to be
sampled.;
