in my application i simply read the raw midi device. then you
just have to parse the bytes as they come in. for a note, the first byte
is the msg type, second (for note on) will be the note-number, and the
third is the velocity. note-offs are either seperate msgs or faked as
note-on's with a zero velocity.
example code can be found out
http://www.bright.net/~dlphilp/dp_devseq.html at least for midi
out. midi in with the raw /dev/midi is the same but uses reads instead of
writes. make sure you do a search and replace for < to < as this
renderes improperly in my browser.
www.harmony-central.com has a link with the midi spec docs you'll
need to read msgs.
this is a short example which creates a loop in and echos it out
for a midi through.
