That's what I thought too, as it seemed logical. but it doesn't work.
Let's say I don't have any alsa-midi apps running. in qjackctl, I only
have "Midi Through" (in and out)
% chuck-jack test.ck:0
this will create a new MidiIn and connect it to "Midi Through (out)".
% chuck-jack test.ck:1
this won't work, with this message :
> [chuck]: MidiIn: couldn't open MIDI port 1...
my conclusion: the port parameter to the MidiIn.open() function is not
the number of the port you open, but the port number of the source or
the target to which it is supposed to be connected.
... which isn't that useful, in my opinion.
