Just send 60, 62, 64, 65, 67, 69, 71, 72 to [mtof]. Or better yet,
send 0,2,4,5,7,9,11,12 to [+ 60]. You may want to search Google for
Peter Elsea's Max tutorials on pitch (and rhythm and chords later, too)

[>] and so on work by sending either 0 for false and 1 for true
comparisons. [> 10] compares to 10. You can overwrite the stored "10"
through the second inlet.
Select converts selected messages to bang-messages. [select 0 1] can
be used to convert a 0-message to a bang at the first outlet and a 1
to a bang at the second outlet.
[select] and a comparison together form a kind of if-else-conditional:
if (x > 10) then do bang1 else do bang2 end
in Pd would be:
[select 1 0]
