I tried to run MidiGraph but I get an error:

Traceback (most recent call last):
  File "./MidiGraph.py", line 7, in <module>

    for btn in self.conn_type_btngroup.buttons():

Apparently, the length is not written:

        elif isinstance(event, SysexEvent):
            ret += chr(0xF0)
            ret += str.join('', map(chr, event.data))
            ret += chr(0xF7)

(And the length includes the F7 bytes.  And I don't know if the data includes
the F0 and F7 in both the Jack and ALSA interfaces.)

Clemens
