These guys are describing a manifestation of the famous embarrassing
three-patch-cord-sorting bug that was fixed in the beta 3.5.9-7
available at

or the Cycling '74 FTP site mirrors.

Coming soon will be a new version that fixes even more fun bugs
we haven't even discussed here.

Thanks to David Z. for confirming the following:

I certainly agree. If the Max manual is updated sometime, maybe this could
documented? Thanks also to Stephen Kay for a neat little trick of the trade:

>Add 1 to the output of active.  So front becomes "2", back becomes "1".
>Then add a closebang which sends "0" to the same destination.  Now

I'll edit this and forward to Unauthorized Max FAQ.

We've done banks of same model consumer MiniDisc players with Max talking
serial or MIDI to a 3 card AMX rack loaded with a MIDI card, serial card
and IR card, with cable run from the IR outputs to an IR LED that mounts
directly on the front of the unit (there are several types of these as
they are standard fare for high end home AV installs). AMX catalogs IR
codesets and provideds a librarian, or you can purchase their capture
device.  In any case, the implementation took a couple dozen lines of
code.  Max would send a unit ID and then a command ID, and the AMX box
outputs solely to that unit.

Works great...  Not as cheap as the Infra MIDI, but works I use Max and AMX together as often as possible...I'm a
sucker for anagrams
