Two simple questions

[Jeremy Cowgar]

I have been typesetting simple (single note melodies) music, adding lyrics 
and chords.

I am curious: #1. How I can skip a chord on a pickup measure? i.e. 3/4 time 
and the first measure has only one beat, while the last has the other two. 
I know in the notes area to use \skip 4*2 in that instance, but in the 
chords, the first chord is not played until the first full measure. How can 
I do that?

#2. When outputting the midi file, the tie on notes seems to be ignored. 
For instance g'2.() g'2. is tied in my PS file but in the midi file, two g 
notes are played.

Thanks,

Jeremy
