Hi developers,
We’ve been having a discussion about midi. I could say a lot about this, but
I’m sure some developers have thought a great deal about this, and probably for
many years, so I don’t want to second-guess.
As I report in the following thread, I’m a software developer, mostly
experienced in C++, and have thought maybe I could assist in such a project,
but naturally I would first want to know if a) there’s any interest in outside
developers contributing to the midi output quality and b) what has gone before.
Thanks, and I’m a grateful lilypond user.
