[sdiy] comparators vs. clamping diodes as gate inputs to microprocessor?

[Danjel van Tijn]

I have been exploring lot's of different options for interfacing
gates/clocks  and CV to microprocessors.

Several people on this list have been very helpful and offered some
good examples.

However I am split as to whether to use a comparator or a pair of
clamping diodes for the gate/clock inputs. The clamping diodes simply
ensure that the gate voltage falls into a strict voltage range but the
comparator would at least allow weak clock sources (i.e. low voltage)
to be boosted...not sure if that is really relevant.

Anyone have thoughts on this? Most of the solutions I have seen
involve using comparators but Seb's clamp diode inputs (on his
website) look like a  nice and simple solution (and cheap).
