Legato and Polyphonic Voices

[Emir D.]

Hello everyone,

I've got a slight problem. In measure #1, I've got the non-polyphonic melody. In measure #2, I've got some polyphonic going on. However, I'm having problem telling Lilypond to put a legato from the last note in measure #1 with the first voice in measure #2.

Can you help me, please? I've provided an example .ly file, so you can see what I've been trying.

p.s. Also, in the example given, in the first measure, the flags of the last four eight notes are connected. How can I tell Lilypond not to connect them, e.g. instead of connecting the four eights into one group of notes, to rather group them in two group of two eights?

Thanks in advance,
Emir
