[CM] midi-received functions

[Taube, Heinrich K]

its not clear to me what the issue is. does it not work.
BTW no need to use send() and just call the function directly so

> send("mp:midi", key: key, vel: vel, chan: chan)

can be written

mp:midi(key: key, vel: vel, chan: chan)

i thought I got rid of all that in the documentation and help files.
