Re: wrong beamlet direction in 6/8 and 3/4 measure for dotted quaver and semiquavers

[Martin Straeten]

i found further examples with less different rhythms
Bach English Suite 1:

page 15, 5th system

page 1, last system

This kind of beaming within 6/8 seems to be quite common (at least in
former centuries). In the last edition this is used as well als the c8~c16
d e f so it seems to be an intended solution.

I havn't found a real life example, where the beamlet is sticking out to
the dotted quaver.

Your idea regarding a "no beamlet sticking out" property seems to be a
practicable solution; the workaround described in the issue is fine for the
simple example, but is quite inconvenient in real life.

kind regards,
Martin
