Thats odd. They were referring to 0.8.6 but I tried configuring 0.8.6
with --enable-alsa and I get:

configure: WARNING: unrecognized options: --enable-alsa

libasound was not a dependency of 0.8.6. I think they had their
versions confused or mixed up.

ok. I think everything has been removed. It compiles fine and the
plugin directory has been removed from git.

I don't think there is any more that you need to know about JACK MIDI
to do what we need to do. All you need to do is take the info in which
Alex gives you, look up the actual midi code (in the table link I sent)
and send it over the interface we created in the fashion in which he
recommends. Maybe I am can help on that but I am not sure how. Perhaps
I will have to talk to you in IRC or something if you think that I can
be of help. If your run the program kmidimon it will give you an idea
of how the midi controler messages work. The table alone would not be
enough for me. In kmidimon I moved the pitch bend wheel (without
pressing the note) and there was about 30 similar midi messages sent
out from the controller. Each message was just the message type and
bend amount. If held in the bent position then a note is pressed. I see
the note on. I release and see note off. Then note sound sharper than
normal. Then I release the wheel and another 30 similar messages
giving controller type and wheel position. The wheel can be released
before noteoff also. This would create a portameno. Alternatively I can
hit note and then bend wheel. I would have to look up if this is what
is used by midi to use different tunning systems or not. So I don't
think attaching this as a directive to a note is a good idea or not.
Unless it can be triggered before or after the note. Perhaps standalone
would work. Can we control precise timing of standalones? Prices timming
would be required. Is this what you are looking for? I don't mean to
frustrate you but I am confused on how yo help. I am at most I am
getting 3 hours of sleep a night and I am constantly surrounded by
distraction. This is certainly effecting cognition.
