My understanding is that the -b option restores PMX's beam groupings.
This is much more complicated than simply "beaming on 8ths."

Does this mean that Christian could simply force the paired 8ths
wherever he wants them?
The "beam-grouping" algorithms in PMX are rather complex. I won't try
to explain them here. In some earlier versions, I included an option
to specify alternate or additional beaming rules. Describing how this
worked took up several pages in the manual, and to the best of my
knowledge no one ever used it, and it made the code more complicated,
so I eliminated it. Neither before nor since can I recall anyone
suggesting any change in the defaults. Again to the best of my
recollection, this is the first time anyone has suggested
(re-)introducing an option to globally alter the grouping rules. At
this point it would be a significant programming task to make this an
option. It would be quite a bit easier to change the default, but of
course I am not going to do that. As I explained in my "Future of
PMX" posting, my attention even toward high-priority additions and
bug-fixes has been deflected recently, so even if I were to add this
to the "to-do" list it would not receive attention for quite some
time. If Christian feels that he cannot accomplish what he wants
using forced beams, and if he has or is willing to seek out the
ability to compile the FORTRAN, then he should contact me directly and
I will explain what needs to be done to the source to change the
default beaming rules, so he can make a private version that suits his
needs.
