  Hello Ralf and everyone else on the list,

thanks a lot for your help so far!

Ok. I wrote a small script and it's going nicely. I think, I don't really need
a session manager.

My problem is a little different.
Here's a list of the MIDI Outputs:

neptun% aconnect -o
client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 129: 'Hydrogen' [type=user]
    0 'Hydrogen Midi-In'
client 131: 'yoshimi' [type=user]
    0 'input '

These are the ports I can choose from in seq24. The problem is that the
numbering may change when hydrogen and yoshimi are restarted. Therefore some
patterns in seq24 may get played via the wrong MIDI port.
Is there a way to attach hydrogen and yoshimi to a port with a fixed number?

  Best regards,
  Hendrik
