Why not ? (Didn't get the point here ...)

Yes. I had certain doubts when I replaced A-type CMOS
with B-types in my (still unfinished) sequencer around
the ARP Sequencer core. Fortunately it didn't cause
problems (which speaks for ARP's design). The only
problem was from a HC device I got from some distributor
as a CMOS "replacement". No "74" before the "HC", then
a 4000 number. Not this one showed strange behaviour at
15V ! (It didn't explode, though.)
