hi,
i have the following problem: when i use multiple midi-in ports, the midiin object only receives messages from the first port. output works fine to the other ports though..
i found this line in s_linux_midi_io.c in function int midi_instat(MIDIPort *mp)
FD_SET(mproot->devhandle,&midi_rfds);
which i thought was the problem, since mproot is the first port and the function doesnt use the *mp argument supplied, so i changed it to
FD_SET(mp->devhandle,&midi_rfds);
of course, the next line has to be corrected too, so
FD_SET(mproot->devhandle,&midi_rfds); return select(mproot->devhandle+1,&midi_rfds,NULL,NULL,&null_tv);
becomes
FD_SET(mp->devhandle,&midi_rfds); return select(mp->devhandle+1,&midi_rfds,NULL,NULL,&null_tv);
and then it works fine!
