I'd vote for 1ms, because some folks use simple differentiators to
do some functions and 50us might not whack them hard enough...

1ms is long enough for probably any electronic circuit to respond, but
short enough to be a single click to a human (we would not hear both
the rising AND falling edge).

I've done some playing with this recently with my guitar synth... some of
my 20us pulses did NOT work with all my EGs...  So I made them longer
