Hi Jakob

I'm not IOhannes, but I'll answer anyway.

Yes, because the mrpeach library doesn't contain a binary named
mrpeach. In case of mrpeach, it is sufficient to just add the path.
Preferably, you add the path with [declare -path mrpeach] in your
patch, rather than in the Pd configuration. This makes your patch more

You don't see a message, because no external is loaded at start up
(only the path is added). This is unlike the zexy library, which comes
with a zexy binary and which prints something to the console when
loaded. However, from what I understand, if a specific external prints
a message at load time is purely optional. So that is not necessarily
an indicator.

I get the same, and I don't yet understand why it doesn't show,
although a midifile-help.pd file is there.
