Thanks very much Urs -- the tip about moving the \override outside of the \times did the trick.
The
reason I duplicated the entire phrase in each voice is that I want to
see the second group of 16ths in a single-beam group. By limiting the
dual-voice treatment only to the small tuple that really requires it, I
am not able to join the beams the way it appears in the original
Paderewski edition that I am typesetting. My example has the beams I
want, but the slur is much too high. Your suggestion corrects that high
slur, but doesn't join the beam the way I want.
Is there a way to accomplish both? I know that both versions are technically correct, but I would like to mimic the original if possible.
