Re: trillSpan question:

[Kenneth Wolcott]

So, it appears that \stopTrillSpan being placed on the following note
does not include the following note in the trill; I guess that  was
not obvious to me.

The third question is that the trill does not appear in the midi
output, but articulation.ly would implement it?

Thanks again,
Ken Wolcott
