Re: Automatic Piano Reduction with > 4 parts

[Mats Bengtsson]

Unfortunately, the part combiner is very buggy in general and it's
also very limited in scope, for example since it only can handle
two voices.

Have you tried to simply let your three lines of music appear in the 
same Voice context? This is far from a perfect solution, but can still 
work surprisingly well in many situations:
\new Staff \new Voice << \sopI \sopII \alto >>
