Hello,

I've tried this. It seems to work, but it is awfully programmed...
First, i use \ibbu (as using \ibbl and \tbb* seems to keep the lowest 
beam). I change the starting pitch of the beam. I put the note at pitch p 
with lower stem (with no spacing). I shift it to get it a the right place 
and I increase the length of its stem so that its stem reaches the beam. 
Then I put a phantom note to simulate the first note of the upper beam.
  It requires some work but it works...

\notes\ibbu0{`d}6\stemlength{8}\roff{\zql{'p}}\stemlength{4.66}\sk\sk%
\hqsk\islurd1K\qb0{^K}\tslur1L\tbbu0\qb0L\nbbu0%
\qb0b\qb0d\tqh0g\en

regards
