I meant jack/midiport.h is dated 2004 inside,

perhaps they picked up midiport.h from earlier work then, I don't
suppose that Debian is that frozen.

I can do this bit very easily - I have had a look and it is a
straightforward enough bit of plumbing - leave it to me.

yes, please do this - I will just assume it exists, I will use

    if (event.buffer[0] = (SYS_EXCLUSIVE_MESSAGE1 & NOTE_ON))
        return midi2hz(event.buffer[1]);

where my function will be the dummy:

double midi2hz(gpointer data) {
return 440.0;
}

and where I have put "return" but it will be something else
