Yes, apparently, the issue that bites me is that partcombine detects even a 
single note played by only one instrument as a "solo". So partcombine will 
(almost) never print out a rest in parallel with a note in the other 
instrument. In real scores, there is a de-facto threshold before a rest in 
one instrument is regarded as a solo in the other instrument. If partcombine 
allowed such a (ideally user-settable) threshold property, it would fit my 
needs just fine....

I would actually work on it to fix my problems. But looking at the code, I'm 
absolutely lost, mainly because (a) I don't know how lilypond works 
internally (and there is no documentation about this, only the API 
documentation, which does not help with understanding how lilypond works), 
(b) I'm new to scheme, so reading scheme code takes a bit longer than other 
languages like C++, java or python, and (c) I don't really understand the 
data structures used, and (d) the scm<=>c bindings and the interaction of the 
two languages is also not so clear to me...

So, basically, I would need at least some pointers on where I should start 
looking (I suppose in part-combiner.scm, in the determine-split-list 
function...? But then, here my problems start, as I don't know anything about 
the data structures and the way the part combination really works...).

Cheers,
Reinhold
