You could write the times to a file(foutk) but if the tones are being
generated very quickly this could lead to performance problems. In
which case you could write the times to an array and then dump them to
the file at larger intervals. If you could provide some simplified
code it would be easier to assist you.

>From your description and other questions, it also sounds as if you
require high precision both the the tone generation timing and for the
buttons that you want to register as input. Are you contructing some
kind of audio perception/reaction test? In such a case, I would
suggest using kr=sr (set ksmps=1 in the header). As far as I know
(even though we can do sample-accurate event scheduling also with
higher ksmps) the interfacing with the external controls (button) will
happen at k-rate.
