I agree - I have used this same setup, infact running number of Macs
running Director from a single control Mac running MAX. I simply looped
the Serial data back out the printer port on the MAC and chained that onto
the next machine. This solution does away with needing a MIDI interface
for ech machine, and passes much less data. I used a character (ie. A, B,C
etc) to indicate which machine should accept the message followed by a 3
digit number for the cue. I used the first character of the string to
initiate reading the port, and cleared the port after reading the 3
following characters so that the port didn't fill up with junk. This
approach worked really well, was reliable and trouble free, and of course
you can run a serial cable over a fair lenght of space.
