Frescobaldi is not in the pclos repos, sorry.

I did just install 'abc2midi' which has some two way scripts in it, but I
haven't run it yet.

I expect it is copyrighted, its somebodies 'moused into Ultimuse-III'
version of Brian Wilson's California Girls. If Cher has her way, it will
never go out of copyright. :(

I just tried midi2abc on it, and get either an "unexpected byte = 0x22" or
a segfault. So either it has problems, or there is a bad byte(s) in this
archive. If that is so, then likely I have several dozen other .ume's that
I can load and re-export as .mid that will have the same set of symptoms.

Thanks Brendan.
