I've having real problems getting midi support working reliably
between machines and would like to hear some other
input before I log a bug....
it seems to me that if you copy a patch that uses midi to another
computer and connect the exact same midi
controller, the midi support will not work at all until you go back
into the patch, go to the settings for the midi
controller then select the observed sources and select the
controller again....
It does not really surprise me: QC ask Core MIDI for a "universal
identifier" of the MIDI source to save into the compositon, and this
might be a combination of the computer ID, interface ID and device
ID. Changing any of them breaks the link.
There are likely other solutions we could investigate. Please submit
a bug report on the issue.
