Thanks, Mats.

That's exactly what I have done yesterday.
Now, the script generates the voices as before, except:
1) Voice 2 has always \voiceTwo command in the beginning.
2) Voice 1 has \voiceOne when some music appears in voice 2, and \oneVoice
command is generated whenever voice 2 disappears (i.e. has s1 rests).

This works fine.

(Now I do not understand the rest of your message: why do I need
"\oneVoiceInStaff" in the second voice?)
