A 555 timer (poss. the CMOS ver ICM7555) set up as a _monostable_
with a very narrow pulse width (this can be programmed with
a resistor). This would be triggered by the LFO's square output.
This is one of the very things this chip is designed for. The
basic setup for this is in the app notes for the 555, possibly
also the spec sheets for it (all available on the net). This
will give one pulse per full square cycle.
