Sometimes people are way too quick to call things dead. There is a thing
called bitrot where changing lib versions kill older code. This is very
true with code that uses a system GUI like QT or GTK (GCDMaster is a good
example). However, in the case of very basic c utilities that really use
an API that hasn't changed for years, just looking at the git repo and
calling something dead because that last entry is a few years old doesn't
mean anything.
That being said, there are two ways to run a2jmidid, from
the command line as a2jmidid -e and through dbus with a2j_control. I would
advise against using a2j_control as I have found it sometimes "jams" (I am
sure there is a better word) and creates a disk filling log file in short
order.
Do remember MIDI notes come at about 1khz (31k/10bits/3events) chords are
groups of notes... depending on the keyboard scan direction your chord
will always be top to bottom or bottem to top with the last delayed a few
ms from the first. Beside that jitter has to be pretty low frequency to be
an issue. Not that jitter is ok, but that MIDI itself is an issue already
before it gets to the computer.
