How can I start adding an external rawmidi plugin? As you said, there is no
framework ready yet. So, first a framework has to be created so that
external plugins can be added the same way one would add PCM or control type
plugins. It might sound a little naive but I am not familiar with the
framework part of it, but it looks interesting.

1. I think for finding out what the plugin framework would consists of I
need to have a look at alsa-lib and modify it too, is it correct?. If such a
framework is created then
will the control flow look like this:

amidi/aplaymidi ->alsa-lib with midi plugin framework->my_midi_plugin

Can you point me to some code/doc etc which might serve as start point,
basically how do I go about adding such a framework and finally, how user is
going to use
it with newly added plugin? (i.e. for pcm io type plugin we use #aplay -D
my_plugin test.wav, will it be similar for midi plugin also?)
